New fuel lines
My car is an 87 Firebird GTA 350 TPI rear mount turbo using Walbro 255LPH 4th fuel pump.
Im going to try an Ac Delco ep381 pump from a Typhoon to see if it solves my issue.
Due to fuel issues where my pump heats up wines and looses pressure, Im considering changing my fuel lines just to a new aluminum line. I need some info on thread sizes I would need to use to the filter and to the rail.
Im sure there are threads about custom fuel systems on here with info and pics would be helpful as well.
I was reading on a GN setup where guy using a Walbro 255 LPH pump changed his return line to a 3/8" line, is that something to consider?

Seems like a few of us are having these symptoms, I just want to be able to tune and drive my car.
