noisey fuel pump!!

darren44 · Sep 20, 2009

evening all.

i have just put a new engine in a td4 freelander and it seems to start and run ok but the fuel pump by the rear wheel is making a lot of noise!

if i turn on the ignition but don't start it then the pumps sounds like it is priming for nearly a minute befor it stops,but if i start the fl then the pump is very noisey like it is primimg but very loud,have not driven it very far but does seem to lack a bit of power.

any help would be very apprietiated

If it's a cheap (£30) Ebay pump with black end cap then that's the problem. I have recent experience with them and know that they are louder and are low on fuel rate and pressure. The original (grey top) pump is from Poland and much better but £130.
Whilst you're there, remove the 2" rubber pipe from the back of the pump and check it doesn't have a plastic blockage within - mine did and caused me 10 days of grief! For all I know, it could be a strengthening inner that collapses.
