Isuzu Bighorn 2.8 turbo intercooled, 3door manual.

[Tom]

Hello. I'm having problems with an air leak in my injector pump. I have checked everything else up to the pump. When I pump the primer on the diesel filter I can see a drip coming from between the pump and the engine. I can't get to the problem without removing the injector pump. Question:- Is anyone familiar with this problem?. Is there a fix without removing the pump? Can someone reccomend a good mechanic who listens in Invercargill? Thanks Tommy.
