Not to hi-jack, but my '02 4 liter Jeep GC fuel pump seems to be getting louder the more I drive lately. Jeep runs fine. it has roughly 178k on it now (pump is original untouched)....should I think about replacing it now before it dies? I also saw on the link for Rock Auto, that the Delphi unit is the "premium" brand...consensus is to get the delphi part?
