Fuel Leak When Filling Tank Ron Mears 4-7-07  
When filling up my 1986 Class A Journey three weeks ago the pump stopped after only $36. The tank had been right between 1/2 and 3/4 of a tank when I started filling up, so I knew it was no where near full. I know now it was not a bright thing to do, but at the time I pulled back the circular rubber piece around the nozzle of the pump and kept pulling the lever. It kept stopping, so after 3-4 attempts I went inside and got my change.

When I came back out I heard the horrible sound of gasoline dripping on the pavement beneath the motor home. It was coming from a 3/4" rubber hose sticking out over the top of the frame near the gas tank. There was a hose clamp on the end of it, but the hose was wide open at the end. By the time I got a screwdriver to tighten the hose clamp, it had about stopped leaking anyway. Besides the clamp had nothing to clamp down on anyway, just the end of the thick rubber hose.

Fortunately, the RV was sitting on about a 10-12 degree slope inclined toward the front of the vehicle, so I was able to put it in neutral and let it roll about 20 feet past the puddle of gasoline on the pavement. I got out again and went inside the station to alert them to the fact they had gas on the ground, but this was in a remote area and no one answered.

I checked again to make sure there was no gas leaking on the pavement again, and sure enough, it had stopped. I checked inside again, and still there was no one there.

Finally, I started the motor and drove home. Once parked again, I put a piece of siding under that part of the coach so I could check for any stains in the morning, but there were none. The leaking had totally stopped, and in the past 14-20 days there has been no further leaking.

Thinking that the presense of the hose clamp meant that the hose was meant to be plugged at that end, I got a plug and plugged it today.

Now, after a little Googling I'm finding references to gasoline tank vent tubes, so maybe plugging the end of the hose was not a very good idea either.

Anyone have any idea what happened at the gas station? And does that hose sound like a vent tube? Should it be plugged?

Thanks much.
