Noisy fuel pump Options

[Ian Stott]

Boy we had a beautiful day, all the snow is finally gone and I cleaned up the teener, wish I could post pic's cause it actually looks pretty good! Went for a nice drive on country roads, twisty's, you know what I mean and the car ran great. I found running 30 lbs all the way around works best with the Dunlops that are on it. My Fuchs are quite dull and I am going to get them polished hopefully in the next few weeks. I do have a relatively loud whing sound when you turn the key on and haven't started the engine yet, fuel pump is my guess but I haven't been around any other 914's so I don't know if this is normal or not. Any help here much appreciated.

it's one of 2 things.

The fuel filter is plugged and the pump has to really work to draw gas...

Or, the pump is failing.

Usually they happen together.

One more thing, the fuel sock in the tank could be clogged.

In any event, replace the filter, cut the old one open, and look at the filter paper to see if it's clogged with rust or gunk.

I run an unpressurized filter in front, and a pressurized filter after. That way no crap gets to the pump or the injectors.
