I just noticed a slight fuel drip on our 1995 U320. The engine model is M11-400E and the serial is 34753953. The hose that has the leak is attached to the fuel pump and the hose has a tag that says 7023. The hose enters a group of hoses and goes toward the transmission end of the engine. Before I investigate further does anyone know where the hose goes and if it is a Cummins or a Foretravel item? Thanks!
You might try contacting DAVE HEAD. I remember him replacing the fuel lines on his 95 U320.
Sounds like the hose that goes to (or comes from) the fuel filter with the batteries on our 1998. Generic boat diesel fuel hose is sold by the foot, and ends are reusable. No need to even loosen the ends from their attachments.
