I have a '73 2.0 (the fuel pump was relocated to the front by the PO).
Lately I've been hearing some noises coming from behind dash/frunk area. It sounds like a pulsating strained noise (almost sounds like a duck). The noise isn't constant. I don't recall hearing it when I start up, but I definitely hear it when I pull up to a red light or get off the highway. I feel like I've narrowed it down to the fuel pump because there's nothing else on when I hear the noise (fresh air box or heat fan in rear). My question(s): Do fuel pumps make noises like this before they're about to die? Could it be something else? Here are some pics ... Attached thumbnail(s) |

I have the same or very similar pump. I hate it ! If it sounds like a duck and looks like a duck it must be a duck . Let me know if you find a quiet one.

I believe it's a Bosch or at least looks like the Bosch pumps online. Who can recommend a quiet pump? |

I believe it's a Bosch or at least looks like the Bosch pumps online. Who can recommend a quiet pump? Airtex E8445. It puts out the proper pressure and volume for the FI on a 914. It even works on the 4.0L 964 motor. I used an early 911 fuel pump mount with rubber isolators and it is quiet as a mouse hiding from a cat. And it can be purchased from FLAPS for about $125.00. The outlet fitting is the same size as the fuel lines in a 914. (IMG:http://www.914world.com/bbs2/uploads_offsite/images.carid.com-1143-1638565067.1.jpg) I cut the nipple off the end of the brass intake fitting and fit one of these on there: (IMG:http://www.914world.com/bbs2/uploads_offsite/mercurycarburetor.com-1143-1638565068.2.jpg) It's a carburetor fuel filter for a 70s ford. But the intake size is the same as the big fuel tank suction fitting on a 914. It protects the pump and works as an adapter. I have run one on Betty's car for over 20 years with only one replacement. And I really didn't need to. The pump started making noise, and I thought it was going bad. Turns out the rubber mount broke and it was hitting the metal of the car. The pump was fine. I just replaced it because I was already in there. I have two spares, but never needed them. The one I removed from Betty's car now has lines and wires with alligator clamps on the wires. I use it as a fuel transfer pump to empty a 914 tank before I pull it. Hope that helps. Clay |
