I'm doing a ls1 swap into a 88 Monte Carlo and need to upgrade fuel lines. I've purchased a Grand National fuel tank/sending unit with the Walbro fuel pump 255/lph. Now I need to replace the fuel lines/filter/regulator and I'm unsure on size needed. I picked up a typhoon intake w/ 85mm throttlebody pretty cheap so will be using that was told I should prolly run 42 lbs injectors and the fuel rails I was told are a brand Bullit but I suspect are the rails that come with the intake and have heard they were junk. I'm most likely going to be replacing the rails as I don't like the color of them.

Any recommendations?

A 3/8 feed line will be plenty. If you can, run a 3/8" return as well, although a 5/16" return will suffice.

I used -6AN lines on my Monte with the GN tank/sending unit/walbro. I am using a truck intake with integrated regulator on the fuel rail so I have lines up and back from the engine.

Need to know more to help you. What what year do you have? Are you using "LS1" as a general term or you actually have an LS1? What are you plans for the engine power wise? Add-on power adders?

I'm hoping for low 420 to 450 hp on motor and maybe a small shot of spray later on
