: Do I need a bigger fuel line??

Apr 21st, 05, 12:18 AM
I have a '67 chevelle originally equipped with a 283. I have since added a 365HP 350 and TH-350. A local "engine guru" keeps telling me that I need to run a larger diameter fuel line from the tank to the pump to keep from chokin'. I haven't noticed any fuel delivery problems but I want to do the right thing. FYI, I'm running a carter street pump (5-6psi) and a 650cfm Demon carb. What do you think??

I'd leave it be, unless your having problems, Ed is feeding a low 10 second rat with 3/8 fuel line.
