Excuse the large image. Best I could find on the net.
So I have an issue with the injection pump on my mini digger. It is a 1990s JCB 803 fitted with the Perkins 103 3 cylinder diesel which would appear to be the same as the one pictured below. It has always been a great starter (have owned for 15 years) but has started to get wet around the FIP of late. Today she failed to start and after trying to bleed it up I noticed quite a bit of fuel is coming out of the flange where the fuel injector supply pipes attach to the top of the pump. The ones held down by the 5 sided bolts on the picture below. I did manage to bleed to the injectors and she started up straight away but fuel was dribbling out of the unions of at least the first 2 aforementioned flanges and dripping on the floor. When I stopped the engine and tried to start it again, it took some cranking to get it going, suggesting it is emptying the fuel lines pretty quickly. So my questions are:

When I stopped the engine and tried to start it again, it took some cranking to get it going, suggesting it is emptying the fuel lines pretty quickly. So my questions are:
- is there a simple way to service those seals under the flange (guessing not as they are fixed down with 5 sided anti-tamper nuts)
- is it as easy to remove the FIP as the manual would suggest - simply undo the 2 nuts and 2 bolts holding the pump into the body of the drive unit and lift out? The manual makes it look that simple. There is no mention of setting timing or anything like that? It is unclear if one or more of the bolts holding it in may be reverse thread. Is anyone able to confirm reality?
- where would I be looking to sent the unit to, in order to get those seals changed or the whole pump reconditioned?
