thinking ...
frankly, i do not know. the idea is to keep the pressure and to get a constant flow without bubbles or vapour locks.
mounting the fuel outlet at the rear may help, but here we found a complaint at 3/4 of tank volume.
one thing is for sure:
the return line should flow easily. that is: enter the tank at the top.
i do not know if connecting before the tank with a T to the pressure side will help.
plus: the pressure line should be thick enough. 1/2"at least.
i had too many customers with the holley fuel injection that did use the stock 3/8 or even 5/16 line with bad results.
