I got under my RV (2006 Gulfstream BTCruiser) to clean and repaint some rusted spots on my propane tank. While on my back looking up at it I noticed a plastic plug covering a threaded connection.Anyone know what that is for? Could it be to attach a propane hose to in order to fuel something like a gas grill?I also noticed that my gas tank has lost some of it's black paint and where it has it looks to be rusted or corroded. Yet the tank looks like it is galvanized or something like it. Should I clean and repaint it or leave it alone?Thanks for any help with my questions.

The gas tank on our ford is all stainless construction. The outside looks cruddy, but hey, that's a dirty environment under there.I'd leave it alone.Regarding the port on the propane tank... I have no idea.

If this unit had a previous owner it could be a port for an Extended-Stay. Or depending where it is installed in reference to the regulator it could be a low pressure port for a gas grill etc. But I'd bet on an extended-stay.http://www.amazon.com/Marshall-Gas-Controls-536-00-Extend-A-Stay/dp/B002UC4T6C

BruceMc - I did not think it would be a metal that would rust. Mine must be stainless as well. Thanks.

bobsallyh - I am the original owner so whatever is there came with the tank as installed. It taps right into the tank and not the regulator. I am aware of the Extend-A-Stay item, however I had no idea it could be threaded right into the tank. Thought I had to get a new regulator that would accept it. Thank You.

Where on the vessel is the threaded port located?
