Larry,
I have the fuel pumps mounted on the engine side of the firewall.? I have a short
run of the kit-furnished fuel hose from the fuel tank to a fitting inside the
fuselage (at the hole provided for this in the dual stick bracket). The rest
of the fuel lines are braided. I mis-matched some components in this first fitting
and had a leak there, pressured only by the hydraulic head of the fuel
in the half-full tanks.? Once that was corrected, I have had no leaks.?
The fuel selector is in the center of the center console.? I have had no problem
getting fuel to the carburetor.
I absolutely did not want the fuel lines in the cabin to be under pressure.? The
only reason I could justify having fuel pumps at the tanks would be to fill
a header tank that feeds the carburetor by gravity.

I'm using all aluminum and AN fittings inside the cabin.
My reason for the pumps in the wingroot centers around the Fuel selector valve
in the cabin. The valve (per the plans) winds up about 12 inches (give or take)
and is most certainly the high spot in the fuel system
I was (and still am) concerned that low fuel levels in the tanks would lead to
a
low enough head pressure to not get usable fuel past the valve.
In which case the pumps on the firewall have nothing to pump.
Thoughts??

Dave,
Not to worry about ethanol eating aluminum. The trucks delivering the
stuff are using aluminum to convey and transfer
the ethanol as well as lots of vehicles burning the stuff with aluminum
in them. I'm running aluminum tanks and lines
and burn 87-octane with 10% ethanol. Do replace the fuel filter and
short rubber hoses each side of the filter every year though.

I'll be replacing the kit supplied rubber fuel lines which the
previous builder put in the wings. I plan to use stainless steel
tubing which is sold in coils for brake and fuel lines with AN
hardware and braided line with earls fittings where there may be
flexing or routine service. I had rubber fuel line (for vapor
recovery at the tank) fail on a 2003 model U.S. made vehicle in 2005.
We used copper fuel lines in older cars for many years but don't know
how it would last with today's mogas. My fuel pumps will be on the
engine side of the firewall.

All-
With the HD/HDS you have no choice but to use some of the rubber
fuel line. If not, you'd have a hell of a time getting the wings on and
off. Also, you will be under pressure (Suction, actually) in the cabin
for a short period of time while you fill the header from aux tanks. No
problems reported from either Larry Mac or Jeff Small.
As far as ethanol is concerned, I'd be more worried about it
dissolving the carb gaskets than the fuel line. Someone mentioned an
alcohol testing kit. Testing might be a necessary addtion to your
preflight procedure in this day and age.
Reports from HD/HDS people with headers encouraged.

Larry,
My plan is to run the braided line through grommets to the selector valve. I
am using the center stick and following WW's "Corvair/601 Engine Installation
Manual".
Once the wings go on the plane and everything is plumbed and wired I hope to never
have to detach them. If I do need to detach them though I will just disconnect
at the tank and remove the wings.

| Subject: | Re: Fuel Lines and Fuel Pump |
Gentlemen,
I agree with Jeff's opinion on the aluminum tubing.
I have plumbed my fuel system entirely with aluminum tubing thus far and will do
so to the firewall.
The only flexible line is from the firewall to the engine and that is the braided
line like the one pictured in Ron's post.
Rubber fuel Lines:
If the rubber fuel line was supplied with the pump and the pump was purchased from
an automotive parts supplier, it is safe to assume that the lines are for
that application and therefore probably will not be affected by the ethanol.
Any fuel line purchased for the automotive application should be ethanol safe.
Hose clamps:
Standard practice in the Marine Industry is to double clamp all hose fittings below
the waterline for safety. Obviously that would increase weight in the aircraft
application and that would be undesirable.
There are always spring clamps available.
Spring clamps are very common in fuel systems and you can get the clamps at any
auto parts store.
AN fittings are in my opinion the best way to go with either hose or tubing.
Fuel pump Placement:
Fuel pumps are designed to provide pressure, not draw a vacuum.
Obviously they will draw some vacuum but this is not their intended purpose nor
their strong suite.
The fuel pumps should be placed as low in the system as possible but not lower
than the gascolator. They should be placed after the Gascolator to avoid as much
debris going through the pump as possible. Pre-pump filters are common on many
fuel systems. As long as the pumps are below the tanks outlet and are gravity
fed they will pump. I would prefer the pumps be as close to the engine as
possible. I think the firewall is the best place for them.
That being said, the pumps are sufficiently strong to supply the pressure as far
away as the wing roots.
So I think that option should work as well.

MY fuel wing tank selector lever on the 601HDS is actually on the floor
between the seats. I actually stepped on it once and broke the line up to
the main tank. Then when I switched on the transfer pump it pumped fuel all
over the cabin floor (fortunately, I was still on the ground) Important
safety tip, until your fuel system is proofed out, don't install carpet or
anything that might hold fuel after a leak into the cabin..

Hello, all
Despite a nasty cold, I managed to be ready to store the left wing next to
the right wing in the garage as planned: before year end.
All I need to do is to carry it to the garage, attach the wing tip (it is
very hard to go up the basement stairs with it - lesson learned when the
right wing was moved) and place it on a shelf built for that purpose.
So I thought some planning was in order: I visited a few web sites and
stared at a number of pictures of CH601-HD(S) centre wings, refreshed my
memory on the different components, etc.
So far so good.
Then a mandatory stop at Larry C. McFarland's web site - and a cold shower.
Larry's building narrative is covered in journal sections 1 through 7.
He was done with the wings by the end of section 2, and was already working
on the fuselage.
If the relation holds, I need another 25 years to finish my plane...
Sigh...

Welcome to the family Anthony.
They need to be offset. Not by much but a little. I seem to remember there was
a spot on the Rudder that was the same way. You will run into some more places
like that as you build.

Anthony.
My flap skins were not pre-drilled, so I just offset the holes enough to allow
both rivets to be set.? If yours are pre-drilled, the best answer is to find some
Avex rivets that are long enough to clinch the joint, but short enough to
eliminate interference.? You might also try inserting rivets through both sides
at angles to each other and then pulling them a little at a time, alternating
between rivets.
You are going to find, later in the construction, other places where interferences
occur.? This is especially true where you install A5 rivets in both legs of
an angle.? With the tail of an A5 rivet protruding toward the inside of an angle,
there is no way you can get clearance for the rivet gun to pull a rivet
from the inside of the angle. In one instance (on the firewall, I think), I hadn't
offset the holes and had to drill out a whole row of rivets. When I re-did
it,? I set the rivets in the first leg from the inside of the angle (head inside,
tail outside), those in the other leg I set from the outside of the angle
(head outside, tail inside).?
Moral:? Look ahead??? and think!

Zenith will tell you to cock them crooked and while pushing down and pulling
with a hand puller straighten them up as you go. That didn't work for me so I
drove the center stem out and ground the body short enough to fit put the pin
back in and pulled them -worked good- but would do it only with that last
rivet on trailing edge because they won't be as strong.

Don't drill. FWIW, I'll append my comment from my builders log regarding
this problem. It must have worked, because the rivets are in place now.
"3. After the bottom was riveted, the trailing edge rivets could not be
inserted on the top because the rivet on the bottom is in the way. The
pilot holes should have been offset to avoid this problem. I recall there
was a place on the empennage where the holes were offset to avoid this sort
of problem. ZAC really should modify their pilot drilled kits to eliminate
this conflict.
4. Called ZAC; Caleb suggested tilting the top rivet and forcing it in
until an edge was in contact with the skin. Then pulling the rivet with a
hand riveter and moving it normal to the surface as it shortens. He said
that if the rivet could not be inserted until an edge was in contact with
the skin, then the hole should be enlarged with a drill at an angle until
the rivet could be inserted.
After examining the aileron skins for the same problem and looking again at
the flaps, I concluded that the conflict would be reduced if I had riveted
the top- trailing-edge-skin before the bottom skin. It looks like, because
of the angles and placement of the pilot holes, a set bottom rivet
interferes with the top rivet insertion more than vice-versa."
Good luck.

The way to get around this problem is to take the stem out of the rivet and
shorten the rivet then reinsert the stem and you can get it in without cocking
it sideways and making your new flap look like crap. When you get really
good you will be able to race the rivet gun and beat the head to the skin before
it sets but don't try this unless you have set a million gazillion rivets.
Jeff
Greetings, my first post from a new 650 builder,
What are you all doing about the trailing edge rivets on the flap? When
riveting one side the previous rivet gets in the way of the opposite side. Any
advice?
I'm sure there is an easy fix, I'm going to be proof that a greenhorn
amateur can really build an airframe.
Happy Holidays,
Anthony

Hi Bill,
After speaking with Bing folks, I discovered they have reformulated
their floats, gaskets and such same as VDO gaskets on senders
about 5 years ago.

Larry-
I have a $1000 MA3-SPA rebuild, and I don't want to jeopardize the
integrity.
Bouncing back and forth between converting my antenna to HD-TV (Worked
great- I get 15 channels for free- cost me $175 and killed the day for my
son and me) and assembling a family photo montage for my aunt and uncle. I
have to go to Wal Mart tomorrow to have some daguerreotypes turned digital
so I can finish up. These of course are from my, my brother, and my cousins
early years.
I really want to get my uncle to sit down for an EAA "Living legends"
session. My son has agreed to act as cameraman and I'll hit him up when I
deliver the photo montage. He has a phenomenal and atypical story.
If things go right, I'll actually get back to work on the project
Monday.
You have to agree, you can't get the wings on and off with hard tubing.
Bill

Roger-
Mine is too. I'm not quite ready to get in and out of the cabin yet,
so this could be a real problem.

MY fuel wing tank selector lever on the 601HDS is actually on the
floor between the seats. I actually stepped on it once and broke the
line up to the main tank. Then when I switched on the transfer pump it
pumped fuel all over the cabin floor (fortunately, I was still on the
ground) Important safety tip, until your fuel system is proofed out,
don't install carpet or anything that might hold fuel after a leak into
the cabin..

With the HD/HDS you have no choice but to use some of the rubber
fuel line. If not, you'd have a hell of a time getting the wings on and
off. Also, you will be under pressure (Suction, actually) in the cabin
for a short period of time while you fill the header from aux tanks. No
problems reported from either Larry Mac or Jeff Small.
As far as ethanol is concerned, I'd be more worried about it
dissolving the carb gaskets than the fuel line. Someone mentioned an
alcohol testing kit. Testing might be a necessary addtion to your
preflight procedure in this day and age.
