I have a problem a mechanic says is prevalent among Chevy Express 3500 based RV's and wonder if anyone else has encountered it.
The smell of gasoline in RV house started as whiffs occasionally on short trips. During yesterday’s trip up valley the strong smell of gasoline set off the Propane Detector several times. There is no sign of leakage under or around the RV, and no odor up in the engine compartment. I crawled under the gas tank and traced the gasoline fill-tube up as far as I could reach toward the tank and touched a loose bracket or fitting near the end (felt a hole I assume held a bolt), but couldn’t see or feel anything more. I suspect the junction of the gasoline fill-tube and the gas tank is the culprit. The stop and go traffic may have gotten the gasoline sloshing around enough to spill out while moving but nothing showing up underneath when stopped.
I imagine I’ll have to empty and drop the gas tank unless someone knows a tricky way to fix that junction I can’t see. Thanx, Gary
