whining noise from the rear

[onesilop]

On the weekend as I was warming up the engine and walking around the back of the defender, there was a sound like a whining noise. I think it is some kind of fuel pump but I dont think it has made that noise before. It basically made the same noise the entire time the engine was going.

Any idea if this is a "Normal" noise or is something about to go bang?

it is a 99 TD5 defender.

Probably just the pump but they can appear noisier than usual if the fuel level is low.






or on the way out

should be the fuel pump.

you should hear the same sound when the key is turned to the second stage.

my fuel pump is really loud and the sound changes a the fuel sloshes around.

i guess it's normal.... it still works =D

I had assumed that it was the pump, and feared that it was on the way out. It is going in for a service next week I will get the mechanic to take a look.

had the same problem 3 years ago , a very noisy high pitch noise from pump , drop the tank and fitted a brand new pump and guess what same fault, have put up with it since and only time it,s noisy is when the fuel is below half , good luck let me know how you went

The tank was full when I noticed the noise, not sure that bodes well for me....

Once when I heard a very loud in-tank fuel pump it turned out to be the outlet hose kinked 90% closed. I suspect it was over pressurising/blowing off its relief valve. Filter change time? Fuel pressure regulator too high?

I have had to replace the pump before, not cheap :eek:
Howveer you may be able to save it - mine started whining so I pulled it out and it was clogged with algae, a good clean and the whining went away. The hard part is getting the pump out, there's a thread on how to make an access hole in the rear floor somewhere.
