1991 BMW 318i Q&A
1991 BMW 318i Question: do I have to replace the whole fule pump to replace the filter sock?
If you give me the last seven digits of the VIN# I can check in the parts catalog if the sock available separately, I can give you the part# also if available. Zee - ZeeTech
if the filter is new I'd change out the pump and the sock, so that way you save yourself costly repairs down the line best to do these as a one shot fix - sparky8265
