My almost new Walbro 255 went out the other day. There was a small metal part rolling around in the plastic fuel reservior where the fuel pump sits and all it did was stir the fuel around in a glass bottle when I bench tested it.
Well, I just recently switched to running 50/50 E85/91, so a natural question was, "Did the E85 cause the problem?" I called Walbro to see if the pump was covered until warranty and they said no, suck wind dude. Ok, that's fair, it's a high performance part and it did last a few months, whatever. I then asked if their pumps were ok to run with E85. The lady I spoke with said no, absolutely not. I asked if she meant they just weren't rated for E85, but that it probably would work. She said no. I know you can get failure from the increased workload and gunk that the E85 cleans out of your tank, but the filters didn't look that bad (looked worse when I took out the stock fuel pump) and they were new a few months ago.
This runs contrary to everything I've seen about E85, including local tuners and those I've read about online. I talked to AGP (got the new one from them) and they have people they know running the same pump with E85. Anyway, I call BS on pump failure from E85. I'm going for it again. If this one burns up, I'm going back to stock and getting a real car.
Anyone else who's running E85 having issues?

well im on stock fuel pump and ive been running e85 about a year now and havent had any problems and to be honest i think its makes my car as whole run better b/c when i go to prem. some times things just dont sound right. thats just my 2 cents

Thanks for the response. The stock pump is a Walbro too. My car runs awesome on the E85 mix. I finally got the scangauge, installed it and I get zero knock at 24psi in 100 degree weather.

on what turbo? what are you afr on WOT? im getting FRL put in and im gonna retune it but im thinking its going to run harder richer. but im just gonna play with it, but im also running 100% e85 trying to find e100, hehehe. how much power u putting down?

I'm on the SST v2 and all the other stuff in my sig. WOT AFR is 10.5 - 11.0 which is very safe. You can run up to 11.5 if you are pure E85 from what I've read. 10.5 on E85 is roughly equivalent to 11.5 on gas in a stoichiometric sense, but with the extra octane and cooler burn many push into the mid 11s safely. You have to be monitoring knock of course to do this. I don't know how much I'm putting down now, but with the stock turbo/mani/O2 and 75psi FPR I put down 297whp/348wtq. It's alot faster now, but I am still fighting a small tuning issue where it bogs on gear shifts.

oh ok. im hitting 12.5 on afr but no knock tho. i have an e1 turbo but when i bog on gears i took more fuel out and went away.
20psi falling to 18psi. but the less fuel the less power
That's pretty safe. You are not really pushing that turbo hard, so as long as you can monitor knock and it's good, let it ride. When you add more boost and are starting to get into the high boost regions(this is subjective I know), I would get down into the mid 11s AFR-wise.

ooh yea i am that why im taking it to get the FRL put in b/c i cant get no more boost without it and my motor is running retarded but pulls hard as hell tho so i cant wait to retune with the FRL kit. at about 24ish psi
the reason your pump failed is cause your running e85 (85%ethanol, 15%gas). ethanol is very corrosive. i posted a reply on someone Else's tread yesterday about the same thing. ya its 104-105 octane and cheaper, but u dont have a flexfuel or ethanol vehicle. see materials such as certain types of metals and rubber, dont do well with ethanol, they corrode or deteriorate, which in your case, well u found out.

I was looking for people who have run E85. The only one who has responded has run E85 for over a year with no problems. I talked to AGP and they said they know people who have run E85 with no problems. I've talked to local tuners also, and they haven't had any problems. Also, I'm not running pure E85. Do you have a failed pump due to E85 or have you seen an example of it? If not, thanks for the lovely input.
