Interesting, what type of lubricant would one use that today's fuel would not dissolve in a hurry?

I like the idea of cutting a piece of nitrile and putting on there. I have one on my truck, Stant, from Napa and it is cracked but not yet broken up yet. Over a 1 year old now.

Updated, something to definitely to consider, Viton is the product to use in this application.

So I just checked my cap and that gasket comes right off there and is cut in a circle. This one is going to be an easy permanent fix.

I love the internet for one thing, information collection:
