Has anyone else gone larger on the fuel line?
I'm switching to an 8AN fuel system for my Roush 427R-095 in anticipation for new side pipes from Buckshot Racefab. I already changed to larger carb, 2 inch primary headers, more surface area on air filter and high volume 100 micron Aeromotive fuel filter. I'm going nuts waiting to have all together and testing.
I think the line with all the other changes will add some nice gains.
My Superformance fuel tank is beautiful stainless work, but had a 3/8 inch pick up line. I replaced with 1/2 inch pick up to 8AN through the rest to fuel pump. I'm putting on a higher volume mechanical Carter fuel pump too.
This article is an interesting read.
