I will be on e85 next season with a 2nd pump,inline along with my DW in-tank. Looking for suggestions on the 2nd pump. A DW is ok by me if it's suitable...it will be on full time. FWIW i am dealing with all restrictions on the return side...and new -10 feed etc... Also, what would be an acceptable way to wire it? Lastly,will be adding 1 inline filter between the pumps and looking for micron # suggestions. Thanks.
If I was going to install a fuel filter between two pumps, I would use a 100 micron filter......purpose would be to catch any pieces of a failed primary (1st) pump from screwing up the secondary (2nd) pump. In my humble opinion, it is best to go to an external pump with a 100 micron filter between the tank and the pump and a 10 micron filter between the pump and the fuel rails. Conrad
I would recommend this external one, Pierburg from Racetronix: http://www.racetronix.biz/itemdesc.asp?ic=WSP330&eq=&Tp= Edit: Scratch that, just realized its compatible with E15, so don't know about it's longevity with E85
It's hard, but the Bosch Motorsports 413 will (but expensive). And they both are rated for E85 (500 hrs).
