Im trying to save myself a lot of work, Im converting my 20XE from 45s to Jenny injection, not wanting to have to cut up a new tank that I have just installed, and run extra fuel/return line. on a previous build BEC there was no return plumbing for fuel, can I convert My Jenveys to run as a non return system? or will this open a can of worms with things like bleeding air, and fuel vaporisation?
Surely you could put the return feed in with minimal "damage" - a drilled hole (in the top or side) with tube inside tank to return fuel to
bottom of tank and return feed from front or car- all sealed by compression/gaskets
Something like this

I added a small pipe to the fuel sender fitting on the basis that if I screwed it up, it was replaceable. Worked fine.
I used one of these Aircraft tank fitting
If it's cleared for aircraft use that's good enough for me

Now im really confused, just checking over the Jenveys, and not quite what I was expecting, the fuel rail only feeds from one end, the other end is a
blank,
It will have a pressure relieve valve with a return to the tank, it’s what’s known as a dead head system.
You can have a pump that will not pump past a certain pressure but these usually have some form of ECU control
The simple non-return dead had fuel rail usually uses an in tank fuel pub with built in bypass any other system will need a return
