Thread: Noisy Fuel Pump/Filter after changing Fuel Filter on TD5 Defender

Did you cycle the fuel pump 5 or 6 times after changing the filter? Ignition on and wait until pump stops cycling, ignition off and repeat. Always works for me.

I cycled it 2 or 3 times, with no effect. I have been for a couple of drives since then, one for a good 3 hours, and it still sounds the same at ignition on.

The vehicle drives the same, so no ill effect on performance. My only concern is that I'm not stressing the fuel pump out, leading to an early demise (with my luck, while on our holiday).

I'll try cycling it a few more times this afternoon when I get home.

Thanks!

Something else to check, when you removed the old filter, did you check to see that the small rubber oring that seals against the filter and housing/thread came away with the filter? I had it stay behind once and ended up fitting the new filter with an additional o-ring. Produced something similar to what you are describing.
Mine was also getting noisy some time ago, so decided to drop the tank and pull the pump out for a look. Quite a bit of **** covering the intake screen on the pump. Cleaned it all up and it did make a difference. I do it annually now, through a plate cut into the tub above the pump.
Plenty of threads on dodgy fuel pumps too. Consensus seems to be if yours is still going at between 150 and 200k, get yourself a new/spare.
Best of luck.

Umm if you don't already know the vehicle has a self bleeding mode. Just turn the ignition on and depress fully and release the throttle pedal 5 times. The check engine light will start flashing as it enters the bleed mode. Just leave it for about ten minutes while it goes through it s various cycles.
