I'm building my fuel system and wondering if -8AN is enough to support 1000rwhp or less on e85.

Combo is a 2005 5.3 with the usual LS9 gaskets/ARP studs, LS6 intake intake, and a 7875 turbo. Cam still TBD

Plan is to run dual Walbro 485lph pumps intank. Car is a '97 BMW 528i with M5 3.15 gear rear end and a Rossler powerglide.

What hose should I run that is e85 compatible?

Can I run the same Earl's fittings as regular high pressure EFI hose in a dedicated e85 system? I have a ton of fittings I'd like to use up.

Will 120lb injectors be enough if I run more like an e50 blend to hit 900-1000rwhp? I can get the Holley injectors at a good price. Most likely get one of their regulators as well.

Thanks!

-8 will work fine. You should run PTFE hose which will not work with the hose ends you have. Not sure on the injector size.

I run the Holley 120lb and have -10 feed/retrun and 8 from Y to rails then rails to reg. I went through Nate and he said -8 would be fine but I wanted some room to grow. As for hose, I have PTFE, its great.
