Small diesel leak from fuel pump....

[RussRST]

Ok so i have a small diesel leak which is leaving diesel on the floor. It looks like its building up on the gear box then dripping off. It seems to be coming from the fuel pump area but i've stared at it for ages and its very rare to catch a single drip.

Is it common for them to leak? I'm guessing they are not cheap new so was thinking of getting a decent condition used one off ebay and swapping them over? I did have a garage check it over before needing to make a long journey and they pointed out it seems to be the pump but not leaking bad enough to worry about the journey now i'm back i just want it sorted.

when i first bought mine i noticed a small leak,my mate who has the same van said his was the same so must be quite common, ive highlighted the clip i undone and cleaned thoroughly and it did the trick for me]

[RussRST]

Ok thanks I’ll give it a go got nothing to loose

[kst68dog]

just make sure the pipe is pushed right back and clip is put back nice and secure

[RussRST]

So I did that now engine won’t start!?

[kst68dog]

it's just your fuel pipe have you pushed it back nice and tight? im sure it will start with a few tries

[RussRST]

I reset all modules with laptop and kept trying and it eventually started ran rough for a bit but not seems to be idling smooth. Ecu light has cleared but im assuming it might come back on will have to see. I see i can do a manual egr regen does this take long?

[kst68dog]

Pleased all ok, mind i didn't have to do all that i just fired it up can't remember if it took a few goes probably did. Never done a manual regen of egr so wouldn't know mate sorry should;t think it would take long but honestly wouldn't know

[RussRST]

Took it for a drive and lights still haven't come on for egr problem i found a blow fuse so hopefully that's all sorted. Still seems to be seeping diesel and all around that hose connector is dry so it must be coming from under the pump or the seal into the engine. Might just leave it for a garage to sort out.

Ok mate good luck with it
