Hi guys. Havn't gotten any answers on thirdgen.org so I figured I'd try here. My question is that I am putting a 5.3 with an MPT76 in an 86 trans am but I am stumped on what the best and most efficient way to route the fuel lines is. The car is in a full restoration right now so there are NO original fuel lines or anything on it....it's a shell and I'm starting from scratch.

I have a 4th gen plastic tank and pump with the dual walbro 255's rigged up, and plan on running 1/2 inch aluminum line as the supply line. I'd like to keep it simple and only have the fuel supply line going to the engine bay but I am stumped on how to set up a return line. I saw the vette fuel filter idea but I think this will restrict my setups fuel delivery. This motor will be around 600 flywheel horsepower and I want the upgradeability incase I do a forged bottom end so I want the fuel system to be around 800HP capable.

Any help on a the most simple setup is much appreciated! Thanks guys.

I'm assuming I'll need aftermarket rails for your said set up since the factory ones only have 1 inlet? And what your saying is I need to have 2 lines going to the engine bay; 1 supply and 1 return?

Theres no way to just have a single feed line and creat a return under the car back by the tank?
