Probably not what you’re interested in, but I run dual AEM 320 E85 pumps staged in a surge tank. I use my stock fuel hanger. I have plenty of fuel left left putting down 617/443 dynojet with turbo.

Never understood why so many use surge tanks, when they make dual hangers? lol

I actually had a FB hanger for years. I went surge tank because the hanger leaked and had fuel starvation. I can practically run on empty with a surge tank without worrying about fuel starvation during hard turns and acceleration.

Walbro just announced the release of the new 525 pump. This new pump now flows the exact same as the newly released DW400 at the pressures turbo cars typically run.

Flexer commin in with that FIRE! Thanks bro. This will def. be replacing the 450 in my car now. May add a BAP just in case but this may support what I need on its own
