    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.

    Those pumps leak. Is a Thermos pump for search purposes. They have 4 rings. The little one under the poppet valve is a bother to remove and replace. There is (was?) a guy on Youtube with a good video and I recall him selling a kit with the 4 orings. I've just matched them up in the past out of an Oring assortment.
    You can also replace the little valve on bottom with a Euro style NRV as in the post linked. (this is a good fix)
    You can also get a fill cap with a shrader valve, and pump it up with a bike pump
    Such good looking stoves.

    Good on ya for finding the pump leaking before you lit it, or it can get hairy. If you need more info let me know.

    I watched the video and ordered the kit and two sets of rings. It seems pretty straight forward and the tool makes it seem easy. I will update once I get it and if I was successful. The rings were $5 and the kit (which includes a set of rings) was $10. minimal shipping cost too. I think if I take my time I can replace them all. If I can, I have a few more lamps and stoves I will be repairing.

    You may want to take a look at my repair attempts on the pump of that model HERE, including the use of a chopstick and tape to enable me to insert the O-ring serving as a non-return valve, rightly referred to by Majicwrench as a bother to remove and replace.

    I didn’t have the benefit of a kit, but located suitable sizes of O-rings. They held for a time, then a telltale mist of fuel could be detected on the pump rod. I replaced the whole pump, with some adaptation, with a Tilley lamp pump …

    That has a well tried-and-tested non-return valve mechanism (no chopstick required to replace the seal!) and has worked flawlessly ever since.

    An AGM pump will fit as well, and has a standard pip NRV.

    Some of those THermos pumps, even with new Oring in the poppet valve, will leak. Thus I put in the Euro NRV, which is simple to do.

    When you are done replacing Orings, I would encourage you to pump it up, and let it sit while, unlit, and make sure everything seals.

    Looking forward to further reports
