Just replaced the sending unit and noticed the exit was 3/8". My line is 5/16" and was wondering if anyone ran 3/8" all the way to the carb and if it made any difference. Newly rebuilt 289 with Edelbrock Performer Package (600 cfm carb), with Jegs manual fuel pump (not hp), .040, built heads guessing around 275 hp. Is it worth the hassle to run 3/8"?
Thanks,
Duane
