 I can't s= ee a reason why you can't use them before the fuel pump, all the cars tha= t we worked on (when I had my service business) that had external fuel pu= mps had the filter between the tank & the pump.

Kevin,

 

I have know idea why EFI filters cannot be used on the low pre= ssure side as long as they do not restrict flow. Hopefully someone will c= hime in with the facts. I am planning on using EFI filters before my pump= s also. They are the same ones that Ed and others are running on the high= pressure side. They have a large 16mm in and out. AC Delco GF652. I beli= eve the Egg subi's are also running these filters on the low pressure sid= e.
