My fuel pump sounds rough as fook at the mo on tick over kind of a real loud "Buzzing"???
As fuel gets lower it gets louder and louder until i top up!

Would a dodgy pump make much difference performance wise?

you might not have a knackerd pump it might just be thatthe fuel pump noise dampening rubbers are knackerd and the pump is vibrating of the inside of the mounting bracket mounted to the floor.

i am pretty sure its a problem with the pump and not its mounting brackets because it really whines when it is low on fuel so much that it embarasses me.

A noisy pump should not make much difference performance wise m8, my pump starts getting real noisy when am low on fuel just above the red so I try and keep it above the quarter tank all the time! A pump off an xr3i or 1.6i orion is the same if it gets too noisy

Mr.h.

Thanks for the replies chaps ill have a closer look 2mo!

To be honest ive just had a new pump and its fine just a small amout of buzzing which i think is normal but you should expect it to be louder when really low on fuel as i think all pumps to this

a noisey pump, theres gotta be something wrong with it, its proberly tired anyway if been on there from new,

as said before, a good fuel pump on a rst is critical for fueling, as the years goes by the pump loses its smoothness of the flow, leading to lean fueling and a blown up engine, so u might aswell replace it anyway for a piece of mind

as above, a seriously whinning pump means its dying generally.....and it will make a difference to performance, ie. lack of fuel!!! at best a bit of a power drop, at worst a melted engine

mine gets like that when low on fuel another thing to add to my list og bits to replace

Too the lads that replaced their fuel pumps..................Did you just buy a standard pump from youre local friendly Ford DEALER or buy an aftermarket uprated one????Regards Micky

Do not trust a noisy pump. The cost of the potential damage could be the difference between the price of a new pump (£100??) and a rebuilt engine (£2000???)....
