RV particulars:
Driveline (Engine, Transmission): Cummins 275 hp, Allison 6 speed
Miles: various
Year:1997 Fleetwood discovery
Break Down Description: I had several fuel lines break on my old Discovery over a 4 year period. Finally, in El Paso, tx one night, a young hispanic mechanic, who spoke no english, was able to show me that the engine was missing the brackets/clamps that held the fuel lines on the engine so the engine vibration wouldn't break the lines. There should have been several brackets, and all were missing. Four years of grief, with 28 warranty claims on the engine for broken lines or related issues, like fuel damaged gaskets, oil seals, fuel soaked turbo sensor, etc.
Effect: much disgust...
Cause: poor engine assembly/mechanic error.
Outcome: After four years, problem was solved with the fuel line clamps.
