I have a 97 Dutchman C-class. I just recently bought it and have noticed that when I fill it there seems to be a small leak (just droplets really) from the tank when it is being filled but stops when I stop filling.

At first I thought maybe it was some sort of overflow issue but I'm thinkin now its quite simply a hole in the top 1/4 of the tank but its weird that it only drips when the pressure is on from the nozzle an only a bit then stops?

Any ideas on that one as well as repair solutions? I cant see this being a cheap or easy job and I like to be as educated as possible when dealing with our local RV dealership & service centre whom seem more scammer than reputable business (kind of jerks too). The local heavy duty truck repair shop sometimes might be the better bet?

Do they make patches for a tank or am I looking at a new one? Any experience in this issue is greatly appreciated!

Sounds like the leak is in the vent tube which runs right along with the main filler neck. I've run across that before in pickup trucks. It may appear to be at the tank but you'll most likely find that its leaking from the vent and running down the filler neck on the outside only to drip from the tank, giving the appearance of leaking from the tank.

thx very much. Any ideas on a fix or can I just leave this. Like I said, it only drips when filling up past 3/4 of a tank. It would however be nice to fill my tank right up without leaving a puddle underneith me. I'm sure the puddle is only 5-10 cents worth and only looks worse than it really is.

this kind of leak is dangerous because the gas evaporates quickly making it an explosive hazard just looking for an ignition source.
if you can find the source of the leak you can stop it permanently with a product from JB WELD called JB STICK. the part number is 8267-S. it is available at most auto parts stores and some discount stores.
