I'm looking at another build With E-85 and needing some advice on a better fuel pump alternative. My trans am has 3 external Walbro pumps, 2 of which required replacement after a week of running on E-85. I'm not sure if it's an issue with ethanol or what but a lot of the pump manufacturers say "not for use" with E-85.
I use Weldon pumps on my Malibu and haven't had any problems with them, but haven't found an E-85 pump from Weldon.
Does anyone have good recommendations for a high horsepower external E-85 fuel pump? Prefer a large single pump over going the multiple pump setup again. (easier to troubleshoot!) Looking at one to support 1000-1200hp.

Thanks for any advice!

Fuelab has acouple that would work.

Aeromotive Eliminator, if you don't get carried away with your base pressure.

We have used both of these, at just a tick under what you are looking for, we log fuel pressure religiously, and see no signs of it dropping off.

We now have two setups with the new holley pumps, one working and one not finished. But they are looking very capable.

hope that helps.

Use a weldon. They are capable with E85.

You need a fuel Pump capable of 1600 horsepower(quick in my head calculation, its actually 1560 after real math.) I am partial to Magnafuel Pumps. I personally would run a MP4303.

I'm running two Walbros with E85 and haven't had any issues 36 months or so. I have several buds running Walbros on E85 also...zero issues.

He wants 1000-1200hp. Two or even 3 255s won't do that.

Understood, I just didn't want others to think the Walbros go bad with e85.

if you get a weldon, buy some earplugs also.

automagic made over 1100rwhp on 3 255's, e85, auto, etc....

Thanks for the help guys, I'll check the Weldon's first (with some optional earplugs!)
I have to admit though for the price that Holley is hard to beat!!

TheLS1Lover

I know Justin has, he also has a BAP. And is out of pump with the BAP cranked.

I would really look into the Magnafuel. Lots of success with lots of people. They are not that loud either.

I'm running a magnafuel 4303 with e85. It's not that loud and it's rated for more than what you need.

I have been running the Magnafuel 4303 for over a year and a half and I use a 1:1 regulator . I have run a base fuel pressure of 43psi and at 29 psi boost using E85 and 160lb inj on a turbo V6 it held a steady 70+psi. I have since put in a PT88 lq4 and run it to 15psi boost with 160lb inj and e85. I have been 10.1@133 with the v8 and afr has been rock solid.

Im going to be running the magnaflow 4303 on my E85 76mm nova. I've heard a lot of good things about it. Same with weldon as well.

Running twin external walbros on my personal car for two years on E85 without issue.

For a single pump, the Magnafuel 4303 is hard to beat. I put one in a guys car that made 859rwhp on a conservative Mustang dyno through an unlocked 4L80E and 9". It works well on the street as well. He regulary drives it in traffic in the city. Use a -10 feed, return, and two -8 vents. From my understanding a Weldon cant do that without the controller and is load as hell.
