[rebel-builders]Rebel - fuel tank outlet...

Hello Bob
I do not plan to change the standard fuel system, my opinion was more for those who want to change it! And I prefer run both tank at the
same time

Hi Jean !
I would strongly recommend just going with the standard Rebel
setup - one valve at the rear of each tank. You can run with "both on"
if you want, but you have the option of closing one if it is feeding
faster for some reason, ...or you put mogas in it, just to get home,
and don't want to mix fuels, and want to use 100LL from the other
tank for takeoff & climb. Also handy if one tank is leaking - at least
it can't drain from the other tank if it is 'off' ! (They DO crossfeed -
surprisingly quickly !) Also, you coud run off the leaky one first
to get the most mileage & minimize risk ....
Not saying that leaks are common, but it could be you have
a loose or missing gas cap .... or something !
You've heard often enough on this list - 'Every change you make
adds weeks/months to build time' ! I would suggest that changes
can also add extra risks .... just "GET IT FLYING" !! :-)
I'm more with Rick on switching tanks, but not rigidly into
half-hour rotation - seems like too much work ! ;-) I take off
& land on both - to be sure of flow. Run until I see a bubble in
the top of EACH sight guage - so I know BOTH are draining.
Then switch off right side - burning from left to at least 1/2,
to lessen the weight imbalance - me one one side + fuel,
vs just fuel on right. By then, the extra weight gets to require
stick pressure, so turn on right, turn off left. Run to about 1/2,
then go back to left only - go until about 1/4 or less - enough for
a powered precautionary landing, then switch to right only,
and run until dry if necessary, even slipping at get the last drop ....
Have done this intentionally several times (to drain tank) - NEVER
had a problem with keeping engine going. Just turned on other
tank after sputtering & power loss, then turned off the empty tank.
Really, there will be VERY few times you have to worry about
fuel shortage in a Rebel - it holds about 50 % more than a C-172 !!
I always keep the tanks full, unless doing just local flying -
that gives well over 4 hours flying.... usually beyond bladder
range, so fuel stops are not a problem ! ;-) :-)
Looking forward to you flying on a Ramble - soon ! :-)

I will never, and say never have a 3 way valve in my Rebel. I do not like
the idea of a empty tank in flight. So you have to let some in it
