Hi,

I have a diesel leak from the fuel pump, it appears to be leaking from near the cold start lever, presumably an o-ring?

It seems difficult to get to without taking the pump off, I can't even really see what's involved, it looks like a circlip to remove the lever anyone know whether its doable without removing the pump and what's involved?

Less optimistic about doing this without removing the pump.
manual here
I have found the manual, looks like 11 tiny components to drop and 2 o-rings to swap  :run

Remove the pump.

For the extra effort (removing 3 bolts and timing it again), it will be so much easier to work on a clean bench.

Getting the cold start lever back in the holding screw is near on impossible with the pump in place.

Just my tuppence.

Thanks, I removed the pump, it the end. a good job because one of the torx bolts rounded, trying to get it undone, would have been a nightmare on the engine.
