Can i use e85 on a stock fuel filter (paper type) ?

I have been told that e85 damages them and that i should go for a stainless steel type.

Can anyone confirm/deny this?

Cheers, Mike

 

It will make your sock on your filter very dirty due to it cleaning out your system. I would recommend changing yours soon after switching over.

 

Thanks.
I was talking about the filter in the engine bay, not the sock thats on the fuel pump.
But good info none the less.

Nevermind, I see you are not driving an Evo.

 

Please explain how such a thing would be possible?

I have reused my sock that had gasoline for 30k miles. And added 8k miles of only E-85 usuage with absolutely no difference on the sock or any gunk/dirt build up anywhere.

And if your talking about the injector gunk build up. It is not caused by cleaning off the "old gasoline residue" . It is caused by some gas stations and or suppliers adding an additive to the E-85 . Normal gasoline dissolves that gunk buildup very quickly.

 

it's all relevant. Most mitsi parts are interchangeable.
my car is pretty much a 2600lb evo...

 

"Additives"... "old pumpgas" whatever it was made my filter on my walbro filthy after switching over to e85, using a new filter during install.

 

Well, I started to write that the Evo doesn't have a fuel filter other than the sock but then I reread your post and, yeah.

Anyway, if you are worried about rust, if you have a steel fuel tank there's that. Then there are the steel fuel lines. I cut a DSM fuel filter open once and found the fuel goes from the can side and then through the filter. So, any rust from the can would be caught by the filter.

As for the paper, it is really more like cardboard. Still, if you got water in there??? Maybe the Evo route is best - no filter.

 

The EVO has a filter built into the fuel pump housing. Do not go without a filter ever. All the double pumpers use an external filter because they eliminate the stock filter in the pump housing.
