Noisy fuel pump

Hi guys,

I've done a search, and couldn't really find anything. My fuel pump seems quite noisy. The noise is coming from underneath the car around the rear drivers side door (UK car, so it's RHD). The car drives well, and makes good power, but I'm a bit concerned it may leave me stranded one day. Is it a common problem and is there anything else it could be? I can get a video of the car running so it can be heard if that makes it easier to diagnose.

Cheers,

Oli.

Is it a high pitched whine? You shouldn't be able to hear it unless the rear seat cushion is out of the car, and even then it should be only a moderately apparent whine that rises and falls with acceleration/throttle response.

Unless you've drained the tank and are running on fumes, it's likely working harder than normal & burning itself up in the process. I'd suggest replacing it. Just be sure to do the replacement on an empty tank...

I just had mine done a couple weeks ago and I could barely hear it with the rear seat cushion out; with the cushion back in I can't hear it at all, even on a low tank.

You don't indicate mileage or last fuel filter change. I would change the fuel filter; if the old one is bad, the pump has to work harder to push the fuel against the clogged or dirty filter.

This too. If it's been several thousand miles since a filter change and you like to run the tank dry on a regular basis...then the pump will go sooner than later. Of course it's all dependant on mileage.

I've no idea when the filter was last changed to be honest. I'll change the filter and see how I get on.

I just noticed that mine is making a lot of noise, searched, found two threads. So, what happened when you changed the filter?

What I assume is my fuel pump (high pitched whine, changes frequency with RPM) is EASILY audible inside the car. Even at highway speeds I can hear it well. The fuel filter has been changed within the last 20k miles by the PO (my father). The car has 94k on it.

Is a loud fuel pump always a sign of a failing pump? Any "tests" that can be done to determine pump health?

It isn't the sign of a healthy fuel pump

If it is noticeable enough that you notice it while driving it is time for a new one.
