My fuel pump is going out in my 325 and was wondering if anyone has replaced them with an aftermarket unit? I am assuming its possible since the fuel pump is external but I have not been able to find any aftermarket ones listed. I can get a Bosch pump for $135 so I may just go that route but was also hoping maybe an aftermarket unit might be a little cheaper. Would like to have a pump that would be capable of moving more fuel, I do eventually want to do some fuel system upgrades. Later.
