No, don't have a spare unfortunately, but to strip the pump out and exchange it is a bit overkill if I can fix this one. This seems to be the problem, that disc screws into the pump body , this seems to be where it is weeping from.

I reckon I need to take this off and see how it seals up, I don't know what is in behind it in the pump body though.

I don't know but would a 2.5 nad pump fit and crucially, work? To get you out of the poo?
I've got a good (when I removed it 5 yrs ago) nad pump you can use untill you get yours done.

Thanks Flossie, thats very kind of you but the hassle of fitting a new pump is too much, ive had a look at the dampers online and it seems they seal with two O rings, ive contacted a few cav pump dealers to see if I can get replacements.

Pump change is a fairly easy job if you have a pump sprocket holding tool. Only a few quid off the net.
Secure pump, remove all fuel pipes, and the wire for stop solenoid, undo not,pull the pump taper out of the sprocket.
You have to wobble the pump about to refit the taper and keyway in the sprocket, and pull it in on the nut.
Some people remove the oil filter adaptor from the block to get extra clearance, but it is possible to do it without.

So is changing this leaking damper, unscrew, fit O rings on new, fit little ball in hole, screw in new one. Ive got the part numbers now and an exploded diagram, I just have to order them up now, comes to just shy of fourty quid so should be good to go. Thanks though buddy, thats good info to know.

Best of luck, will be interested to know how you get on. I have mixed experiences of repairing them, some worked, others I ended up taking it to the specialist.
Normally I only attempt very minor repairs.

I forgot, if you ever do get a pump tool, there is a steadying bracket on the pump you have to remove, but it is only 3 bolts. I really recommend the tool, clever piece of kit, inexpensive, and saves hours of work messing around with belts.
