My van has been trundling around with a whiff of diesel for a while so investigated it as it I noticed diesel actually droppinbg on the floor.
After checking tightening and generally going mad looking for leaks it turns out it's leaking from this part of the pump when it's actuated by the LDA valve when fully opened - had to go for a drive with someone in back to spot it in the end as it wasn't leaking every time I tried to find it stationary!!
There is movement in the part up and down but none side to side and there appears to be a seal there. Is the seal a simple fix and readily available if so where from or is it new pump time??
It leaks from the end of the screwdriver...
a little research in!
