Noisy Fuel Pump TD5

OK... so when I brought my 90 TD5 a few months back, one of the things listed as recently being done was a replacement fuel pump (which would seem true given he hadn't connected the fuel lines back properly, which I discovered 3 weeks into owning it when I ****ed a tank full of fuel out down the local high street!!).

Anyway... the pump has always been noisy since I've had it and this didn't change when the pipes were reconnected (correctly). The mechanic who did this commented on it and tested the voltage being used which I think was 9 (I think that's what he said... not a mechanic myself so might have terms wrong but if was defiantly 9 something). While he said this was higher than he would have expected everything else (pressure, etc.) seemed fine and it was probably just a noisy pump.

This is my 1st Defender... had disco's before this so don't know if this is the norm or common, but my gut is telling me that while a Defender is not considered the quietest of things... a consent loud hum isn't right! Plus I can't hear all the other normal knocking, tapping and crunching going on so I feel I'm being robbed of the true enjoyment of owning a defender

Thoughts, comments would be greatly appreciated.

Mines always been a noisy pump even though I've replaced a few. I do find a new fuel filter can quieten it down though so might be worth a try

Thanks Gazman... certainly worth a try

with a noisy pump something is not quite as it should be if piped up correctly at pump and filter head apart from pump id look at injector washers and air bleed valve

Thanks James... are these easy to check and sort out? Happy to turn my hand to most things... Have tools and Haynes manual but rather leave it to the professionals if there's a chance of buggering it up!!

air bleed valve is its in rear outer connector on filter head(wjn500110), injector washers arent too difficult

The more things I find that have been bodged on the poor thing, I think you’re most likely right!!

I’m just going to replace the pump, filter, hoses and injector seals and see where that leads. Might be over the top and doing one might solve the problem but rather have the comfort that all those things have been done properly with good parts.

If it ain’t broke don’t fix it, only if it plays up starting

Does a nice cloud of black smoke at start up count? Lol!!
