Best fuel pump for E85
Hello. As the title states I'm looking for a fuel pump compatible with E85. I'm only looking to feed 600-650rwhp.
I like the aeromotive 340 stealth pump but have heard of it failing with E85. Any help is appreciated. Thanks!

I second this post...what fuel pump and size injectors for e85. Im running 13 to 1 compression as well. Should be 600+ hp. What size injector are you running OP? Right now I have the Aeromotive 1000 fuel pump.

Right now my fuel system is stock besides a 255. Upgrades coming this winter. I did the math and I need around 40lb/hr to feed 500rwhp n/a
Do you have any use for the equation for injector sizing?

I'm running dual 340's and have heard of others failing. To try and combat this I'm running a lower base fuel pressure of 37lbs with a 1:1 fpr and 2000cc injectors. It's been fine on e85 all last year and pickled the system over the winter with 93oct. When speaking to Lonnie he mentioned that those that have had pump failure are due to the pump working too hard at higher base pressures and burning up.

I need a gauge for that

Dual 340s with 96lb injectors will support about 750rwhp up to about 20psi before you start dropping pressure.

Those injectors are good for about 1150rwhp at a 37psi base, but you will be dropping pressure as soon as you put any boost to it. The pumps at that pressure flow about the same as the injectors at that level, but fall off while the injectors stay constant.
Moving to dual walbro 450s with the same everything else will carry you up to about 30psi without dropping pressure. But really those injectors are a big mismatch to the pumps. You really need a lot of pump to feed those injectors, triple 450s at a 55psi base raises your injector max power to about 1450rwhp and will carry that pressure to about 30psi of boost. Triple 340s at a 40psi base will carry them to 30psi of boost and be at 1230rwhp range.

Those injectors are way too big for those pumps, or the pumps are way too small depending on how you look at it.
