I just bought a two burner Ted Williams Stove from eBay and the gaskets on the pump assembly are not original and it leaks. Is there anyone who know what gaskets I need or can direct me to where I can get them. I tried a few from the Harbor Freight kit, but they are not thick enough on the plunger assembly. It is leaking out of the pump handle when I am trying to light it. It's the red stove with the faux marble top in black.
