300 tdi lift pump

[smith335]

i think my lift pump is broke.
i changed the fuel fliter,and went to use the lift pump primer to prime the filter,nothing ,cranked the engine incase it was not catching ,still nothing.
there is no resistance when you pump the primer.
is it broke?
what effect will a broken lift pump have on the engine,performance?
do i need to change it?
if so how easy is it?

would anything else point to a faulty lift pump?.

my priming levers never worked on two discoverys, i just put a fuel filter on and start it up, never had a problem. its simple to take off

You might need to wind it over for a while until the filter refills wih fuel.

just had to change my lift pump ,as the disco was slugish so i changed the fuel filter but then could not prime the system easy test is remove the pump ie two bolts then opperate the lever by hand and it should pump fuel my new one was about £30 and took 10 min to fit

thanks for yor replys.
i have filled the fuel filter by hand and the engine starts and runs fine.

i was just concerned that if the handle was not working then the pump might not be working as well.

will the engine still run normal with a broken lift pump?
what would happern if the lift pump was broke,what effect on the engine would it have.

the disco does feel a bit slow,but it is a auto,and i allso drive a td5 disco,so it could just be that, that makes it feel slow.
