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

Kevin,
 
I have know idea why EFI filters cannot be= used on the low pressure side as long as they do not restrict flow. Hope= fully someone will chime in with the facts. I am planning on using EFI fi= lters before my pumps 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 believe the Egg subi's are also running these filters on = the low pressure side.
