Need help finding propane tank part

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.

    You need to visit a propane tank farm the kind of place that supplies the park's propane tank... Many of them can do the job. It may be simple. or a bit complex (from your point of view) it is simple from theirs however.

    That's all I will say. this is not a DIY job

    Question: What happens if you mix propane and air in the proper ratio and there is a spark.

    Answer: YOu land two counties over.

    Room: Breaks down in laughter

    Instructor: (Once laughter dies) Exactly.

    YOU DO NOT WANT TO LAND 2 COUNTIES OVER.
  • Throw a wrench on it and snug it up, then check again for leaks. Or wait till empty remove and reseal the threads. Appears like your dealing with the item in the link.
    Good luck!

    Propane valve
  • The tank manufacturer and model should be stamped on the tank.

    Start there.
