As several have already said, you don't want to fly while sucking gas from both
tanks. I believe the Andair valve construction allows to occur soley to ensure
that fuel is available during the switching process. Imagine switching from
Left to Right (while flying) using a valve that while between the left and right
detent positions allowed no flow from either tanks. One would want to turn
that lovely red lever incredibly fast.

Fellow Listers....
I'm installing an Andair 3-port valve in my RV6a, that is left, right, and
engine. I see it's possible to feed from both tanks however, if valve is placed
between. I believe this is a no-no on RV's, am I right? Not that it is likely
to happen, as the valve has positive detents for left/right positioning. Thing
is though, it can happen, and having intimate knowledge of Mr. Murphy's law,
just wondering if anyone else has noodled about this or has an answer or
opinion. I'd like to eliminate as many "it probably won't happen"'s from my
airplane as possible.
Yes, I did email Andair about it a week ago. No answer... Also checked
archives to no avail. BTW, the valve itself is of jewel-like construction, a lot
prettier than the old brass valve, which did not have this prolem...
My old C-172 had a "both" position, and I hate to expose my ignorance in
front of everyone, but why is it our RV's are not supposed to use that position,
anyone know?

Jerry, Kevin:
Not only is it likely that one tank will feed faster, it may well deliver
fuel from one tank to the other. If the receiving tank is close to full,
then fuel will go overboard either from the cap or the vent.

>> . . . no flow from either tank . . .
Hmm? How much flow is there in the second it takes to switch tanks? Lets see and
assume:
10 gph x ~231 c.i./gal ~2310 c.i. per hour.
~2310 c.i.ph / 3600 seconds ~0.6416666
(or roughly 2/3rds. of one Cubic Inch) of Fuel in the second it takes to switch
tanks?
BTW: If you would burn ~7.8 GPH then it takes 1/2 Cubic Inch per switching second.
Huh, what that coffee does to my early Sat.Morning Brain Activity.
(I was just curious about the numbers, and to see if I was UP YET?)

I've got the round Duckworks light going in an 8. The plans are a little
confusing/contradictory about the platenuts on the ribs. The drawing shows
two platenuts on the top of the rib, but the template only shows one. The
plans say to drill six holes then it only says to install four platenuts. I
assume the extra hole is for more flexibility in aiming, but is this extra
platenut not necessary anymore?

As to the history of leaded fuels, I found this in my very old CAA (FAA)
book entitled Aircraft Powerplant Handbook dated 1949 (CAA Technical Manual
No. 107) On page 172 it says that since Pearl Harbor ---
"Efforts are constantly being made to increase the octane and grade rating
of all gasolines by careful blending of the hydrocarbons, and also by
adding small quantities of ethyl fluid, which contains tetraethyl lead,
ethylene dibromide, and aniline dye."
To me, this says that the purpose of lead is to increase octane rating.
See also this on Avweb (which says lubrication idea is a myth & reps at
Lycoming & Continental aren't authoritative):
http://www.avweb.com/news/columns/182149-1.html
I believe it is becoming more common for "spam can drivers" to look to us
experimental types for accurate, up to date, information about
airplanes. I feel we should help put away the old wives tales that abound.

Thanks to all for the input... Guess I'll stick a placard on in case I ever
sell it and to remind myself... It just is curious to me that Andair goes to
great extent to make this high end valve with a positive lock to keep from going
to "Off" position, but very possible to inadvertantly position in "both"
which "could" be a problem. If the Andair wasn't so purty, I'd be tempted to go
back to the old "Queen Mary" brass valve that was also used on 1976 Ford
pickups, and does not have this problem....

Jerry, I can't believe this is even an issue if there are positive
detent/locks for the tank in use. I certainly never switch my tanks
without without visually checking the handle to make sure it is
position I want it to be in.

OK Konrad- have another cup and figure out what % float bowl volume will be depleted
during same one-second switchover @ same flow rate............(and I have
no ideer what that volume be, neither!) 8-)
Better yet, include time to starvation assuming float set properly- THEN we'll
have some useful data! (or maybe we should just try this during test phase anyway)
Now the F.I. folks may not have a similar accumulator (float bowl), so y'all "might"
have a problem?

How can the valve be designed that is neither full off or both when between

The answer is simple.
Don't buy the one that has a "both" section. Buy the one that has left,
right, and off.
I have one of these valves and it is a no-brainer. I can't fathom what you
are talking about!

Jim, did you actually LOOK at the one you have??
mine is LEFT, RIGHT and OFF, and connects both left and right to the out
during switch over between LEFT and RIGHT, not going through the OFF
position, and you know what, I like it that way.

Quite easy. many valves are designed that way. the ANDAIR could have
been quite easily too, however, if ever the valve gets stuck during
switch over, and that's gonna happen to somebody, somewhere, at least
one tank is always connected. just hoping the switch-over was routine
and not after the windmill stopped due to an empty tank ;-)

Jim, did you actually LOOK at the one you have??
mine is LEFT, RIGHT and OFF, and connects both left and right to the out
during switch over between LEFT and RIGHT, not going through the OFF
position, and you know what, I like it that way.

I think what the worry-warts are concerned about, is the fact that as you
switch from left to right (or vice-versa) there is moment when between the
detents that fuel is fleetingly available from both tanks. That is precisely
why I bought the Andair valve. The fuel flow is NOT interrupted during
switching. So for the worry-warts that inadvertently leave the switch knob
between the detents: What would you prefer? The fuel flow to be interrupted,
(as per the Van's brass valve in the kit) followed shortly by engine
shut-down, --or--continued fuel flow from both tanks (unless the poor
practice of running one tank dry has been done) until you discover your
error and correct the action??----Your choice!!
Cheers!!-----Henry Hore

If you run the boost pump while switching, you will never notice going
through the 'off' position on either a carb or injected engine. Even if
you run one tank dry before switching to the other tank, power loss is
only 1 or 2 seconds (maybe 3 on a bad day) using boost pump on an
injected engine. Maybe 4 seconds if you run the bowl dry on a carb
engine. All bets are off if you don't use the boost pump.
(I know that there are lots of guys on this list who can testify to
this; maybe they are just afraid of admitting to running a tank dry...)

>> As several have already said, you don't want to fly while sucking gas from
both tanks. I believe the Andair valve construction allows to occur soley to
ensure that fuel is available during the switching process. Imagine switching
from Left to Right (while flying) using a valve that while between the left and
right detent positions allowed no flow from either tanks. One would want to
turn that lovely red lever incredibly fast.

One of these days I'll learn to reply to the sender and not the entire

the issue so I may be able to help.
