Took the Boat to the lake yesterday, got home and smelt something funny , looked under the truck and diesel was dripping. It looks like the line, from the injection pump to the fuel rail, is leaking around the connection fitting to the rail. Anybody else have this problem?? common??reason??? anyways do I need to release any built up fuel system pressure before taking that high pressure line off??? and how. 2004.5 cummins. Thanks
