When I have my propane tank filled, gas (vapor)
leaks out of the filler valve.  Looking at the
valve as it's attached to the van, on the right
side you see the four screw heads that hold the
valve together.  On the left side, you see the
other ends of the screws.  My valve leaks at what
looks like a pin sized hole between the two lower
screws on the left side.  Someone told me that the
pin hole might have been filled with a solder-like
substance designed to pop out in case the tank
gets overfilled.

Can this valve be fixed?

If not, does anyone have one for sale?

Thanks,

Matt.
