Hi can anyone help I had a problem with it starting and the problem was with the immobiliser. I have removed the immobiliser at the back of the pump and put a positive (off the ignition) on to the fuel shut off solenoid. Van is now starting and running fine but there is diesel leaking from between what looks like the rear of the main pump housing and the housing at the very rear of the pump that the injector pipes screw on to. Never even knew they could leak from here? How do a resolve this? Does anyone know how the rear housing that the injector pipes screw to is attached to the main housing of the rear of the pump? And how it seals?
