Here's a photo of the return fitting location on my RV10. Bulkhead fitting sealed with Earls Stat-o-seals on both sides.

Are they easy to retrofit on a quick build tank that is already sealed?

My wings were already built when I put my return fittings in. Unibit, vacuum cleaner through the sender hole with some 3/4 heater hose attached to grab the chips. Short wrench through the sender hole to grab the nut. Maybe took an hour to do both sides.

Thanks Bob - good to get a view of this. Looks like your return line entered the fuse near the top of the wing root - do you have any dimensions for the locations or a picture of the location ?

Many thanks, Andy

***this if for a RV-7***

So I finished my first (right) tank and I installed a 1/4 in return line (the same as the fuel vent line). Im assuming this is no good or is it ok with a IO360?!

Is it possible to just plum the other tank (left) with a 3/8 fuel rerun line and only have fuel return to this tank? IE is it possible for the engine to draw fuel from the right tank but return the fuel to the left tank?

If thats possible i could away placard the aircraft to run first on the left tank so it doesn't overfill.

You should return fuel to the selected tank. The return flow at idle is around 99% or about 1 gal/min. The 1/4 inch return is probably ok if you avoid a lot of 90 degree fittings on the way to it.

Default Sanity check

Ok, so I'm building my tanks currently and planning to add a return line as I'm planning on an EFII solution. (Figure I can cap it off if I change my mind later).

I'm pretty clear on where I need to put the return line (or where I shouldn't), but starting to doubt myself on how I'm putting it in. Currently I have an order into vans for two more of the VA-141 fuel flanges. My assumption is if the fuel supply is the same size as the return, all is good? A few posts in this thread are making me doubt myself. (maybe I misread and the concern was how to attach a VA-141 once the tank is sealed since it has to go on the inside?)

Any issues with putting two VA-141 flanges on the tank. One for fuel feed, one for return?
If I go with a AN bulkhead fitting (-6 or do I need larger?) I would need to make an anti-rotation plate for the inside of the tank, right?

Sorry for the possibly silly question.
-----
Nevermind, looks like using another Fuel Flange (VA-141) and an AN816-6-6D Nipple should work just fine. At least that's what I'm doing for now.
