Return line fuel pressure
Can anyone tell how much fuel pressure i will have on the Return line on a TPI setup?Was wondering if i can use a piece of 5/16" rubber fuel line to connect 2 Hardlines together.

Return is never at high pressure. The pressure is absorbed at the inj and/or the regulator, and what is residual IS the return. That's usually just a few psi although it varies with system demand and pump output.
Yessir, you CAN use fuel line on pressure OR return in this system....as long as it is EFI fuel line, and you use barbed fittings. Regular fuel line WILL NOT BE good enough. Must be injection line.
I also double clamp the hose ends to be safe.
