rubber piece in gas cap

[jimmyk]

does anyone know if i can buy a replacement rubber gasket that goes under the gas cap?
  i'm not getting the seal that i should be.
   i already removed it and added some of my own gasket,  it seems to work a little better but would be nicer if i could replace the original.

My understanding is the gas cap comes as a package ($)... no separate parts sold.

Call HDL and ask.

I have read here people modded up their own gasket and replaced or sistered it on top the old one, and it worked (like bicycle inner tube rubber)

You can carefully remove the rubber part and cut a new cork gasket to put it underneath the rubber.  I have done it several times in the last 13 years.

I did the same thing with mine many years ago. I took the doughnut rubber gasket off of the cap, cut a very thin washer made of fiber gasket material to go UNDER the stock rubber and put the doughnut back on. It was a bit hard to close at first but now I don't even notice it. Did it once and its been fixed for 6-8 years.
