Fuel line sizing?

[Tricked-Out-Toy]

Am I safe using a -8 feed -6 return on a 700-800hp pump gas turbo setup? Will it still be ok for E85? whats the max HP itll support? Im running twin intank Walbros.

You should be ok. I'd run the rails parallel instead of sequenced, but those are the sizes I'll be running and I'm shooting for 750-800 RWHP on dual pumps too.

I am using -10 fuel line cause i only wish to to this job once.

I'd just play it safe and run -10 feed -8 return especially for E85. with those sizes you will break the block before you overun them and its only a few more bucks

I agree, -8an in parallel to a -6an return and you will be fine with E85. That combo should be good north of 900/1000 ( +/- )

Guys on pump gas have made 1000rwhp on stock lines(3/8), on pump you'll be fine on 8an, and should be fine on e85 also. Might want to add boost a pumps or another pump though for e85.

I run -8 feed -6 return on dual pumps, made almost 600RWHP no issues, you should be able to get 800-1000 with a -8an no problem.
