Afternoon guys,
I have a 1989 325i convertible. Single intank pump.
Sooo, I replaced all of the soft fuel lines on the car...
Blew air through all of the hard lines and snaked the tank return in case that was clogged.
FPR is a new Bosch unit
Went cheap on the fuel pump though with URO part.
Had intermittent pump whine so I figured it might die soon and so I replaced the pump. It then was louder than the old one. So thought it might be a restriction. Went though everything and it's all clear.
Filled with fresh gas and there still a loud whine... Not crazy but definitely noticeable. No performance issues.
Think it may be the cheap URO pump that's just loud normally?
It is driving me nuts, everything is new except the injectors, rail, and hard lines.
Please help lol
Thank you!
Karl
