so i was wondering what micron fuel filter when running e85

question 1
what micron b4 the pumps

question 2
what micron at the rail

i want them to all be stainless steel

thanks gentlemen

 

fuelab has a nice 6 micron e85 compatible filter that goes nice up by the rail. B&R will hook you up, give him a call.

 

We use 75 micron fuel lab fuel filters pre pump, and at the fuel rail we use 6 micron fuel lab filter. The 6 micron fuel lab filter is a micro fiberglass element, not stainless steel. The smallest micron that Aeromotive makes in SS is a 40 micron. However, I wouldn't recommend this filter post pump. It simply doesn't filter enough.

Stock intank pumps and after market fuel pumps like a walbro use a 35 micron filter sock, then the stock fuel filter is 6 or 8 micron right before the rail.

 

6 micron with e85???

 

I'm not running yet but I went with russel stainless element I think 40 micron pre pump and the fuel lab 6 micron filter pre rail. I wana say the russel filters were $40-50 a piece and the fuel lab filter was $117ish

 

Yes the 6 micron is what our customers use with e85.

 

Im using 40mic before and 10mic after pump.

10mic though is paper element

 

How are the paper elements holding up for any guys running E85? Fuelab says the paper elements are E85 compatible... I'm just assuming they need to be changed more often to prevent the chance of breakdown. Anyone have experience with this?

 

ive been using 100 micron pre and 40 post for a while from aeromotive.

 

Whoops. Ive just got a 40 at the rail. LOL. Oh well, seems to be fine so far.

 

will the stock fuel filter be ok? a buddy of mine running his for the past 6+ months. stock everything other than the usual fuel pump and injectors.

 

The lower the micron the more filtration???

 

I recommend no bigger than 10 micron after the pump. It doesn't take much at all to clog an injector. The bigger the number the more trash will pass through it.

 

Once again thanks for all your imput now go grill some food

 

Its all good with e85.

Before on my twin 044 im using fuelab 40 pre and 10mic after.

Now im on weldon 2035. Im using weldon 40 pre and 10mic after.

 

Anyone know of any filters with -6AN male fittings compatible with E85 and less than 10 microns? I can't find anything on Summit. You guys kind of have me worried now, I've been using one of the Russel filters daily driving it for about 750 miles so far no issues but its only 40 microns, figured that was enough, guess I was wrong. Using a drop in walbro 255 pump.
