how about no filter. Mine came with a small filter at the outlet of the pump that i deleted with a brass fitting from the hardware store.

Id run it up in the bay after the filter and before the injection pump.

If you insist on having it under the car, some sort of capable in line filter will suffice to keep it clean of tank gunk.

Other people that haven`t used a filter were lucky enough to have a clean tank it seems. Will you be so lucky? Or will the pump die in short order?

i like putting it BEFORE my filters.. then the filters are pressure fed, and they last soo much longer..

dont remember the last time i changed fuel filters!

suction is suction.. vacuum..

pressure pushes stuff thru the filter, rather than relying on being pulled thru..

pressure fed is better yo..

not saying yours was wrong, but that filters last better with a pressure feed..

well, there is obviously filter media present, and i doubt 5psi is literally pushing things thru my filter..

my racor 2 micron filter bowl is still spotless, so i doubt anything gets pushed thru the filters..

i run both filters up front, so its easy to get to them..



usually, racor filters arent carried at local parts stores, unless they deal with alot of marine or agriculture stuff..

Run the pump and regular fuel filter up front. It will make your life 100% easier down the road.

A pre filter like those on Mercedes will work perfect. Just enough of a filter to keep junk out of the pump. Filter are cheap and can be blown out.


Mercedes run three filter, with just the normal IP mounted lift pump. A in-tank strainer, and a pre filter/filter up front. No issues unless you get microbes. 


That's my plan atleast. Still have yet to install the walbro lift pump.
