My question is should I change the #10 line from my cell to a #12. Current setup is #10 to Barry grant 5000 filter to a Magna Fuel 500 pump #10 from pump to a Magna fuel regulator from regulator #8 to Holley 1050 dominator. Car is a 79 firebird all steel 455 12.1 with #62 d port head a 630 lift roller victor intake 3800 8in stall 400 turbo and 4.10 gears. All stock suspension except for comp engineering traction bars and 10.5 30 hoosiers raidial slicks. the car best is 10.47 @ 129mph with a 1.47 sixty foot. Reason why I ask car hooks good then kind of gets lazy then once in second runs like crazy. I am shifting car around 6200 and thur traps around 6700
