Greetings from Southern California !!

After filling with gasoline fuller than I usually do - I noticed some dripping fuel when I got to my storage unit. Drivers side - pretty much right behind the mid wheel.

I figured that it must be a vent line since the tanks were fuller than normal. And I figured that some driving would consume enough fuel to stop the dripping. I drove it home and parked outside - slightly tilted to the curb - and no dripping. I guess that I didn't drive enough as it was still dripping when I returned to storage with a level floor...

Upon inspection - I found an unexpected nipple on the forward tank, drivers side, side of tank, near the top. Attached to this nipple was a short section (3" of so) of 3/8" (ID) fuel line that was terminated with an inserted bolt and a hose clamp. This short piece of hose was cracked and deteriorated - and dripping !! So I bled off some gasoline and tilted the coach such that fuel was not at the nipple. And I fashioned a temporary hose/plug so as to not have gasoline venting into the warehouse.

I had other obligations so I couldn't explore further... Could this nipple be the tank vent for early models ?? Is it supposed to connect to the separator in the rear wheel well ?? Might it have been intended for the generator fuel pickup (with a pickup tube inside) ?? Anyone else ever discover this ??

Thank you in advance for any comments and suggestions.
