Hi Mike,
Must of been from a bad batch if the nitrile glove works fine. We will send a couple cap gaskets in the mail. Hope this fixes the swelling issues. Let me know.
Thanks,

I appreciate the response,
Interesting you say the supplied gasket is made of nitrile. I've found that if I stretch a cheap Harbor Freight blue nitrile glove over the filler neck before I put on the cap (sacrificing the glove as it tears when cap removed) the seal will not swell nor will the glove become altered from the fuel contact. Not an ideal solution since there's the risk of particles falling into the cell and clogging the pickup.
It could be that I did get a seal from a bad batch.
I will happily accept your offer of a replacement seal from a more recent batch.

And thank you for the suggestions.

The blend of fuels can cause issues with the gasket as they are normally made for one type of fuel and not blended fuels.
The material is a Nitrile rubber (Buna-N), which is a fuel resistant high quality seal. The problem is with the fuel nowadays and not the gasket itself. A lot of gas stations are using Ethanol/Methanol blends which will attack the gasket after some time.
I would recommend buying a 8-1/2" x 11" sheet of fuel approved cork gasket material at a local auto store. Cut out a gasket to match ours and give that a try.
Other than this, you can have a few cap gaskets on hand and rotate them out. As you said, once they dry it goes back to its normal size. It may be that the gasket you have could be from a bad batch. I can send you a couple at no charge if you would like.
Hope this helps. Let me know.
Thanks,
B*** @ JAZ Products

Subject: Fuel filler cap seal
I purchased a Jaz fuel cell through amazon.com and it was drop-shipped direct from Jaz. I have had problems with the filler cap seal as it will swell and become oversized during use and will not longer seal causing raw fuel to spill into the trunk and passenger compartment. This was VERY pronounced when I was using a blend of traditional "pump" 92 octane fuel and 100 octane unleaded fuel, but still happened when I used only 92 octane pump gasoline. I compete in an endurance series which requires up to 24 hours of continuous driving and fuel spills are not tolerated. I need to know if I were to purchase replacement part BAIL HANDLE CAP GASKET 850-300-01 if that will suffer the same fate or is this a superior material to that which is supplied with the cap when the cell is purchased. I have used the cell only 3 times and the gasket has swollen on each occasion after about 3-4 hours of use. After it is removed and left for a couple of days, it will shrink back down and seal again.
Thank you for any help you can offer to help restore my faith in your "safety" equipment.
