If i'm putting a stock LS1 fuel pump in my tank, why do I need to run the Aeromotive Fuel Pressure Regulator With the stock LS1 swap??

If your running an LS1 F-body fuel pump, then all you need is a high pressure line to the rail. The fuel rail has a pulsation dampner and as you already know, the regulator is in the fuel pump. I have not done the LS1 pump swap, but I see what your getting at and I agree.

 

i run the ls1 tank and the lines up to the fuel filter bolted into the 92's location.. well close enough when i modded the bracket and stuff

i then use the return like for the evap

 

If i'm using the stock 92 tank and just switching out my sending unit for the LS1 sending unit, would I even need to run a return line.....Do the LS1 fuel rails even have a location for a return line..b/c i couldn't find one...IF anyone has a picture that would be great.

i used all of my factory 91 pieces. i did replace the pump with a walbro 340 and picked up an early return style ls1 set of rails with regulator but it works perfect.
