We have just acquired a 1988 Mallard Sprinter and have just started fixin the little guy up. First thing is to fix a small propane leak at the fill fitting. It leaks between that big nut and the square flange that has four bolts into the tank. It doesn't really appear to be a threaded connection but I don't dare start torqueing on that nut till I get the propane burned off and I think it has quite a lot in it. I don't look forward to that. I wanted to just buy a new part and have it on hand before I unbolt the thing but I have looked all over and have had no luck. If anyone knows a source for that square flange, I would really appreciate a heads up. Thanks.
