I assume u are not going to strip down the fuel distributor? As you will
have have a very small chance it will go back together without leaking. I
checked up and to get it serviced in the UK by a Bosch fuel injection main
agent and it was about $500. Ive been told there are $50 of parts needed
which Bosch will not supply to anyone. Have u tried a Bosch fuel injection
agent near you ? Or find a decent mobile mechanic.

Regards

Chris
