under bonnet pump

[elroy]

fitted new ubp yesterday because old one was rather noisy and it was leaking. i took a run into my local town today, noticed that the fuel gauge had dropped a bit ( only 8 mile to town ) parked up and checked under the bonnet to find i have a leak around the pump again. Is the pump at fault or could it be coming from the fuel pipe that goes to the filter ? Any advice would be gratefully received , cheers

Unfortunately that sort of problem needs to be actually 'looked' at. Answers at long range are very difficult to give.

You need to establish EXACTLY where the leak is coming from, check everything carefully, is the UBP brand new unused etc quality item, have you used the correct hose clips to secure the hoses, check everything after cleaning up all the diesel.

Hi, when I did mine last year I found the pipes were chaffed as per the pic:-



Also, as a precaution I wouldn't use jubilee clips choose instead proper pipe/hose clips as mentioned due to pipe diameter. You might have a lose connection. Replaced with 5/16" fuel pipe kit.

Hi Gordon no chaffing on the pipes but the ends where a bit rough so i re-cut the end of the fuel pipe. no jubilee clips used. i will go through the process of fitting the pump again, triple checking everything as i go along, as soon as it stops raining. Cheers

Hi Roy, I used the same pump and changed mine before heading down to Spain last year, I put the old pump pierburg which was still working fine in the boot as a spare on the advise of members, the pump wasn't exactly whisper quiet well, not when it arrived in Spain at least. Good luck hope you sort it OK.

This is timely as I think I may have a problem with my UBP.

When I switch the ignition on I can hear the pump start up. I wouldn't say it is overly noisy but what I am more concerned about is that it runs for between 30 and 60 seconds before it stops when I leave it the key in this position i.e. don't actually start the engine.

This seems a long time or is this normal??

Thanks, at least that's one less thing to do!
