What size fuel line

[Hollowdweller]

I’m stuck on what size fuel line I need to get. I’ll have 3 e85 On3 320lb pumps. If I don’t need all 3 come tune time I’ll prob cycle the 3 pumps every 3mths or so….unless that’s bad? 650hp is the goal, prob be running FIC 1000 injectors, E85.

My On3 fuel hat has -10 supply & -8 return fitting. Prob get BBK fuel rails but I can’t find what size supply hole is on them. Think it said it was 9/16…but that’s not -8 or -10 I don’t think. Think the hose between the rails is -6 an. I’m worried if I run -10 supply and -8 return…..my supply line will be to big…but dunno. Gonna do an Aeromotive fuel press regulator.

You might want to reach out to Palm Beach Dyno. I know they have come up with customer complete systems available for fuel.

Buy a fuel line kit and filter from S&H. The price is very reasonable and all the details have been worked out for you. It worked very well for me

-8 AN supply is likely more than enough but let @JeremyH figure it out for you. He's done dozens of cars, probably over a hundred by now.
