Walbro 405's and E85

[gaspasr]

Spoke with Michael King (global director of TI automotive) and he says the 262 are not e85 compatible. The 267 are. He went on to say that there is even a pump for e100.

The safe bet is to pay the extra money and get the 267/465 pump... I spoke to TI at the SEMA show and he said the same thing the 262/400/405 ( the same pump different names) is a no go in E85... But then you have some that get away with it...

Gaspar, you didn't get away with it.. so you should put in the 267/465 pumps, unless you wanna roll the dice again..

Look at 65fastback, he is running two of the older Walbro gss340 (255LPH) that were no way rated for E85 and the truck runs like a champ...

Yup...had it for a year, put 4k miles on it....raced it, beat on it. let it sit like a garage queen. every bad scenario you can imagine for e85 and it never quit.

Last video I have of it before I sold it

I agree 267s and be done.
I bought my system before the 267s were offered I believe. So I didn't have the option at that time for the 267s. The 267s are just a few dollars more that it's not worth blowing up an engine with a product the manufacturer clearly states is not e85 compatible or warrantied when used with that fuel.

Walbro 262/405's and E85

Spoke with Bill Klinkman, Engineering Manager with TIAuto today and he affirmed that if you used the 262/405 that it would flow E85 at about 50% life or 5000 hours.

At an average of 50 miles per hour that is 250,000 miles. I told him I average 1,000 - 2,000 miles per year. He said I would be fine.

The difference is in 262/405 and the 26/465 is the coatings on the brushes and internals.

According to Justin at Fore, these short mileage failures are not a result of E85, but some other factor such as install or something else.

After listening to Justin and Bill, I am proceeding with my fuel system build with twin 262/405's, Fore Hat and Regulator / fittings, and Stainless covered PFTE hose from Fore. I will run E85 as my tuner and fuel system advisors recommend.

If I only get 10% of the estimated 50% life from my pumps, I will be good for 12 years.

Why would you go with a pump that's not best for your application? Walbro vice president doesn't approve the 262 s with e85. I go for what's best for my e85 application, but that's just me. Good luck man keep us posted with your set up :beer:

Justin with Fore was confident that the 267/465 was sized slightly different and there would be fitment issues in their Hat. Also, the 465 is rated with gasoline and actually only tested 5% more flow than the 262/405 with E85.

Based on usage and expected life in E85, the cost of the 267/465 is not worth the additional expense and trying to find a compatible hat.

I'm confident the 262/405's will operate fine for a looooong time. Long enough before I would replace pumps anyway.

Did Justin said why the 262 / 405 is listed by walbro as a non e85 compatible pump?

 

[JohnsDSGVert]

No

He told me.

I spoke to Justin at length yesterday. The reason they did not rate the 405's for use with E85 has to do with meeting 10,000 hour requirement that Toyota required. The 405's were only good for 8,500. Just like all the other pumps before the 465's.

My 04 is still running on twin GT pumps and has never had an issue. They were never rated for E85 either.

The GT pumps have a plain steel case. The 405's have a stainless grounded case. The only difference is some sort of coating that they would not discuss what it exactly was on the 465's to meet this Toyota requirement.

I would make sure that your wiring is done properly and the pumps are installed at the proper height so they do not contact the bottom of the tank. If either are not done properly it will cause the pumps to fail prematurely.

I would not worry at all about the 405's.

Ill tell you why I think pumps fail:
Its because the pump sits too low and flatens out the strainer, in turn stressing the pump(s)

I did my own measurements when installing my FORE triple pump hat years ago and found the pumps were bottomed out. I called him about it and he Admitted they were all made incorrectly!!! (after I insisted he bench build one and verify)

Take measurements when installing guys.

 

[JohnsDSGVert]

Kevin.....I was a skeptic at first. I heard you out.....did my research.....talked to the right people. Now I'm going forward with 405's and E85 with Fore Hat and PFTE -8 lines coming and going.

If I get 50,000 miles I am fine with that.....the Engineering Manager for TIAuto that says they were not intended for E85 says I'll get 5000 hours or 250,000 miles. I'm great with that.

Thanks for your persistence

No problem John. I'm sure you will be happy with the switch!

 

[Lights of Speed]

So what are actually the best pumps to run with e85?

 

[Demonio]

405 pump

Little of topic what is all needed to run 2 405 pumps as far as wiring? Will like to go this route and go returnless for the moment.

Pick up the pre made wiring harnedd form Lethal.
It is plug and play.

 

[Demonio]

Can a single stage 2 fpdm run this pumps?

 

[Demonio]

The wiring harness is for the dual fpdm right? I'm asking If I can use the single stage 2 because I can get one from a fellow member n will like to know if this is the right choice or not.

You don't use a FPDM in a return style fuel system.

 

[Demonio]

Is not a return style, I wanted to still be returnless.
