Jubilee Fuel Leak

I have replaced the whole unit several times but I still have a couple of problems with it. First, The valve stem does a poor job of shutting off the fuel flow. Second,and worst of all the gasket at the top of the bowl leaks very badly. I have replaced the bowl and have replaced the gasket at least a dozen times using both the neporene and cork gaskets.I have been able to stop the leak for short periods of time but it will usually reappear in a few hours or days at best. I have stopped it temporary by loosen the base and twisting the bowl around on the gasket and then re-tighting the base. When I replace the gasket I can usually stop the leak until I add more fuel or the weather changes.

I have even considered trying to take the bowl and off and adding a in-line filter.

If anyone has any suggestions as how I can end this annoyance it would be appreciated!

Thanks

I've had good luck using THICK gasket paper or the neophrene oring.. just takes an exactor knife and a pattern .
