Hi Jack,
my advice: don't do that. Frank Hinde has on numerous occasions explained,
why there should be two fuel pumps very near the wing tanks. Trust me, Frank
is right on the money. You run a high risk of vapor lock or sucking air into
the fuel lines. It might not happen during the test flights, but sooner or
later it will happen.
Keep it safe

Just a quick note to add to this, if you have a low wing plane in Canada
and wanted to have an inspection to get your flight authority you would
not pass with a valve that has a "both" position on it. So if it is
enough of a reason for a whole country to find unacceptable then I would
seriously consider not installing one.

There is a reason that you list for NOT having a both with a single pump.
You will suck air from an empty tank.
Because of unbalanced flow one tank will always empty first creating the air
sucking problem IF you have both on line.
If your solution is fool proof, don't you think low wing certified plane
would have been using it?
The first thing I did with my Bellanca was to run out of fuel because I had
been flying a Cessna. After I switched tanks, the noise resumed but I
learned to check for fullest tank before I enter the traffic pattern so the
engine didn't get quiet due to unporting in a turn.
For What it worth. Not all high wings are approved for both tank operations!

I've thought about the L/R/B switch problem.
I understand the reasons for not running Both while in the air. I'm not flying
yet, but I plan on using the "Left/Right" method.
But I alos plan on getting a Off/Left/Right/Both fuel valve. But I plan on using
Both only when tying down and will replacard "Both" to "Ground."
Why? Because I plan on putting the gascolator on the engine side of the valve.
If you leave the valve on Left, the gascolator will only collect water from
the left tank. In preflight, you'll have to switch the valve to Right and drain
the line again.
On top of this, I don't know how long to wait after switching the valve. How long
does it take water to flow to the lowest point when mixed with gas? The alternative
to waiting is to drain the gascolator several times to make sure you've
got fuel from the right tank in the drain cup.
How does the list feel about this approach?
Regards,
kk

You are right Cy,
The POH of my C172D said to move the fuel selector from Both to Left or
Right when above 10,000 feet. I spent so little time there that I don't
know if it made a difference or prevented a potential problem. My
Mooney doesn't even have a Both position tho.

Here even in humid Mid-America, I have found little water when sumping.
You need to have quick drains on the tanks and they should be exercised
before going to the gascolator. Of course if one finds a lot of water in a
particular tank one should select that tank and do an extra long sump of the
gascolator.
Many water problems are created by leaving the plane in the weather and
having water leak into the tank via defective caps and gaskets.
It is my opinion that having a "BOTH" even if labeled Ground or some such
label is asking for trouble. You might know, but would your friend
understand this non-standard arrangement? What happens when you sell? Will
the buyer understand the liabilities of using the Both position?
Having the gascolator after the valve is rather standard in the certified
world. Other wise you would need one gascolator for each and every tank
tank. Some planes may have 6, even 8 tanks but only one gascolator. But each
tank will have a quick drain sump.

I know we have gone through this many times before but I don't feel that there
can be too much discussion on safety! One thing I don't understand is the statement"
with a both you will suck air from the empty tank". Wouldn't you still
suck air from that empty tank if you had a left/right valve on that tanks position
until you switched? Same thing with a both. When a tank goes empty you will
have to switch from both to which ever has a little fuel left. This brings
up another point. In the last 10 years I have never run my tanks lower that 1/4
and most of the time I fill up after 2hrs fly time. As far as the fuel pumps
on the wings, why do most low wings hang them low on the firewall if there is
such a vapour lock problem? I am absolutely no expert on this subject and am
not trying to justify my setup ( and still may change the whole setup before the
first flight) ,but after flying in both Cessnas and Pipers, I prefer to make
the fuel system as simple as possible. Both valve
, one
elect pump, one gascolator, one engine. Jack

Jack,
I believe you're right -- the "both" position
shouldn't matter, provided that proper fuel management
is used (not running too low). "Both" will also allow
the tanks to equalize, will it not? Obviously, it
makes sense to use the fuller tank, if levels are
different.
IF you're not going to run a tank dry, there's no
problem, using L, R, or Both, using one pump.
But, if you run dry with 2 wing tank pumps running
(TO&L) into a common line , what happens if one pump
does run dry, with valve in "both" position? Does the
airbound pump act like a check valve, forcing fuel on
down the line, maintaining that engine noise? That
would be the only advantage I can see for using 2 wing
pumps, and ONLY if the selector is in Both .
[confused? .. me too. Where are you, Frank Hinde]

2. I can't see vapor lock (different from running
dry)occurring on the suction side of a pump, unless
the supply line is constricted. And I cannot see how
it would occur on the pressure side of the pump,
except for heated fuel lines forward of the
firewall--different problem.
I'm planning to use the simple approach in the plans
for a valve from each tank Tee'ed into the gascolator
and pump. [ Unless I'm convinced otherwise]

Hello list-
Well my THIRD!!! (Don't ask, let's just say I'm happy to do my part to keep a fine
company like Zenith profitable) rudder kit arrives tomorrow, so I thought
I'd ask some of the questions I'm a little fuzzy on to be sure I am on the right
track and actually end up with a rudder I can use, and maybe help future rudder
builders avoid the same problems.
The demise of the second rudder was twist that I didn't find acceptable when all
was said and done. Here's where I think I went wrong, what do you think?
In the photo assembly manual (Revision 2.0) the instruction "To prevent twist,
the trailing edge is along the front side of the beam..." In the photo next to
it, the trailing edge is shown laying on the beam maybe a half inch or so, and
the tip of rudder spar rib #1 almost extends all the way to the bend of the
trailing edge and is also located above the beam. The rib I received in my kit
was about 1 to 1.5" shorter than this. It ended before tapering all the way
to the point seen in the photo. I placed about 1/4 inch of the trailing edge
on my beam and drilled and cleco'd from there. I THINK what might have happened
is the skin bowed downward a little in the inch or so space between the beam
and actual end of my rib. Does this seem like a logical possibility? For
others who have had twist (surely someone other than me must have some twist
at some time), what do you think caused your twist? What I am going to do next
time is place the trailing edge over the beam and be less concerned about being
close to the front of the beam, but rather make sure some of the rib sits
over the beam, and that the same amount of rib sits over the beam when I turn
it over to drill the other side. Any comments appreciated.
Zinc Oxide in a spray can seems to be useless. It clogs in 3 seconds, regardless
of the temperature. I ended up putting a 'spray popcorn ceiling' nozzle on
the can - significantly larger hole- and dumped about 1/3 the can out onto the
rudder in about 20 seconds. It covered it, but it was sure thick. Any solutions
to this?
Just to verify-are these the steps needed to correctly applying corrosion protection-
1) Wash with dish detergent, 2) Alumiprep 33, 3) Alodine 1201, then 4)
Zinc Oxide. Do you need to scuff the entire surface (or any surface) with scothbright
maroon pad before step 1? Can any of these steps be skipped?
Sorry for the long post, but if I don't get this rudder 100% right, my wife will
make me take up woodworking.

Hello, Joe
It's been a while since I built the rudder, but there are others around with fresher
memories that
will surely provide some good input.
I am building from scratch, and I made forming blocks for the rudder ribs (it's
not necessary -
much easier to bend them on a small bending brake).
The fact is that I did have the forming blocks around, and I clamped them inside
the rib during
the drilling process. This helped a lot to avoid flexing.
You could easily cut some wedges out of 3/4" plywood or MDF for this purpose (round
the edges for
a better fit).
As for priming, I recommend a search, both in the archives and on the 'net. Tons
of info and
opinions out there.
Good luck

Joe: I consider myself a foremost authority on the subject of Tempo Zinc Oxide
after spraying over 20 cans of the rascally stuff. It may have been cheaper to
use a gun but the cans were convenient. When the can is new it clogs every time.
I have found that if you pull the tip off the can and gently place it back
in a new position it will spray strong again for quite a while. Sometimes you
have to do it several times to get it to unclog. Don't push but ease the tip
back on the can until you get a strong spray. I also quit spraying the can upside
down to clear the tip. If it is spraying strong when you finish it will spray
again the next day.
As far as the procedure for priming, I scotchbright, clean with safety solvent
or lacquer thinner, and spray with Oxide. Things are sticking really good so far.
Check back with me in 30 years. Jack in Clovis Ca

You're showing the determination of a good scratch builder.
After you've built the 3rd rudder, the next few pieces you might try making
on your own and see if you can recoup the cost. I'm sure you can do it.

I'd be glad to send photos of the flour-port. (Yes, I DO wish I had termed
it such in the original email!) It very simple, and goes in the floor just
forward of the pilot's seat, and will more often serve as a camera port.
Where's the best place to send the photos so whoever is interested can see

For those who have not seen it yet, sportplanes are setting regional

14 set up. That will be great for builders like us, we can get
transitional training or a sport pilot license in a 601XL. It is also
interesting to see what the factory 601's are going for.

I thought you understood the air sucking. If you are sucking fuel from both
tanks, You will suck air from the empty tank REGARDLESS of the amount of gas
in the other tank. You can not suck fuel if one of the tanks is empty not
even if the other tank is full from a both valve setting.
Now with some systems, once you suck air, it takes a while to purge the
system of the air. The momentary loss of power may happen at the most
inopportune time. i.e... at take off when you are over the trees or short of
the runway.
There should be no argument not to build potential safety hazards. Aviation
is not very forgiving when it comes to mistakes. Why build them in?

As always this discussion on fuel setups is interesting. I also have been
evaluating
which way to go. I believe the RV guys use only one pump mounted on the
firewall with left and right only selection.
Is there really a good reasonn to do it differently than how the designer
specifies?
Has ZAC had any vapor lock issues?
Not being an expert in this area, I'm leaning toward a fuel flow layout
as specified
on the drawings.

cy: You miss my point here. The valve has nothing to do with sucking air. If you
have a left/right valve and you run dry in the tank your on you will suck air
just the same. You will still have to switch to the other. My point is that
if you have a both valve and one tank runs dry and "Sucks air" you will still
need to switch to the left or right tank (which ever hopefully has fuel) and
then kick yourself for calling it that close to start with.

I agree,
I hate the single pump idea but it is kinda ok if
1) There are large lines going from the tank (with minimal
bends/restrictions) to the pump
2) You NEVER suck a tank dry unless you are altitude. Its not certain
from my perspective that you will get the pump purged again to pump from
a full tank.
Pumps in the wing roots is so much more elegant.

I thought you understood the air sucking. If you are sucking fuel from
both tanks, You will suck air from the empty tank REGARDLESS of the
amount of gas in the other tank. You can not suck fuel if one of the
tanks is empty not even if the other tank is full from a both valve
setting.
Now with some systems, once you suck air, it takes a while to purge the
system of the air. The momentary loss of power may happen at the most
inopportune time. i.e... at take off when you are over the trees or
short of the runway.
There should be no argument not to build potential safety hazards.
Aviation is not very forgiving when it comes to mistakes. Why build them
in?

there can be too much discussion on safety! One thing I don't understand
is
the statement" with a both you will suck air from the empty tank".
Wouldn't
you still suck air from that empty tank if you had a left/right valve on
that tanks position until you switched? Same thing with a both. When a
tank
goes empty you will have to switch from both to which ever has a little
fuel
left. This brings up another point. In the last 10 years I have never
run my
tanks lower that 1/4 and most of the time I fill up after 2hrs fly time.
As
far as the fuel pumps on the wings, why do most low wings hang them low
on
the firewall if there is such a vapour lock problem? I am absolutely no
expert on this subject and am not trying to justify my setup ( and still
may
change the whole setup before the first flight) ,but after flying in
both
Cessnas and Pipers, I prefer to make the fuel system as simple as
possible.

George many people change the design to meet there personal needs for
the one plane they will build in there lifetime. I'm no exception I have
strayed from the original plans that Chris has laid out but that is due
to using an automotive conversion with high pressure EFI. But if your
looking for a real valued opinion on a fuel system design why not go
with Chris Heinz's design, after all he has built more planes then
everyone on this list combined and you even have a copy of his design in
your set of plans.

As always this discussion on fuel setups is interesting. I also have
been
evaluating
which way to go. I believe the RV guys use only one pump mounted on the
firewall with left and right only selection.
Is there really a good reasonn to do it differently than how the
designer
specifies?
Has ZAC had any vapor lock issues?
Not being an expert in this area, I'm leaning toward a fuel flow
layout
as specified
on the drawings.

Joe,
You're on the right track here. My first rib was also about 1.5" short, but
if you set up as you describe you should be good. Still not sure how you got
off track, though. The trailing edge is automatically set when the front
edge is lined up with the front of the spar. Let the end of the ribs fall
where they will.
Good luck, three's a charm. I admire your perseverance. You should get a
Christmas card from ZAC this year!

If you are running in the "both" position and the engine quits because you
ran one tank dry, will you know immediately which tank just ran dry? You
will with a left-right only selector.

Now that is a good point Bryan. I do have 2 fuel gauges and I would hope that one
would show more fuel than the other in that case. Second if my tanks are that
low I would be running on either the left or right but not on both. Jack

It's a low pressure fuel pump, typical used on carbureted engines or low

Some of those paintball guns fire their ammo at over 300 ft/sec. That's over

Let's try again. You have the valve on both. It sucks air! The engine
quits.The trees are getting closer.
Which tank do you select to restore power?
You life will depend on it. Which one? Select the wrong one and it is all
over. But which one? Gages are notoriously in accurate. Quick! How are you
going to pick the tank that still has gas? Which ever one you pick, there
will still be a moment where the lines are purging and the engine will not
develop power. For that brief moment you could have doubts and then switch
to the dry tank. Could ruin your entire day and your airplane.
This will not happen if you run a tank dry. You know it is dry and so you
select the other tank. The engine will run. Much simpler!
Fuel management problems are statistically the #1 lost of power problem.

Seems to me that Fuel Management will prevent any problems. I don't want to
find out if any of you that say we will suck air on "both" are correct. I
plan on switching to left or right as soon as I reach half full in one tank.
Then I'll start planning my next fuel stop.

Hello List,
Has anyone fitted this Autopilot to their XL?
I will be fitting mine soon and need some tech info/drawing on mounting the servo
to include in my application to have the mod approved by our PFA here in the
UK.
Thank you in advance,
Norman
