right, fuel pump started to whines like an RC car, so got a second hand one off dan barnes and swapped it. I also cleaned the filter on the intank pump.
It still whines!!!
what do people reckon it is??? fuel filter need changing?
A safe bet Pete, but what sort of mileage on it? My first filter change was at 165k on my old G.
what about the lift pump? If that's worn out maybe the inline one is struggling
i changed the inline one and it didn't fix anything, turned out to be the lift pump as hayesey said
fuel filter has been replaced and looks quite new. I shall investigate the lift pump. It only does it on occasions, but embarrassing at the very least at traffic lights!
right, changed lift pump and it still whines.
I'll change the filter tomorrow... but other than than, what can it be??? would a dodgy FPR cause the pump to overwork? it does seem to get warm when whiiiiiiiiiiiiiiiiiirrrrrrrrrrrrrrrrring and whining
Any chance of a kink or crimp in the fuel line while doing other work? Return pipe blockage?
i'll check connections in the engine bay... its weird as its only really bad stood/at idle.
1. Pipes in engine bay
2. fuel pressure reg
3. fuel filter
hopefully get to the bottom of it!
At it's worst with least demand; starts to sound like the regulator.
i've got a few regs about... will check pipes and reg tonight..
fingers crossed will get to the bottom of this.
pipes seem ok, regulator changed... now seems to behave... but not had a good test. Will test and report back.

Interesting that regs do that. Not heard it happen before, but would make sense.
only thing i can think is that the reg wasn't letting it return to the tank and therefore backing up and straining the pump
