Anyone know what size o-rings are used on the v-6 fuel filters?

I know they're the same for all years and engines of the Fiero, and you can buy them separately. The same fuel filters were used on TONS of full size trucks and other GM vehicles. I have a pack of 2 I bought from a mom-and-pop type store, sitting in my Fiero right now. Problem is the Fiero is 4 hours upstate...

My research shows Viton is the best O-ring for gasoline. Nitrile (Buna-N) is the next best for gasoline.

I bought the Viton set of O-rings at Harbor Freight for around $10.00. It has around 200 O-rings in various sizes. The A011 7.65 x 1.78 worked for the fuel filter. There are 10 of that size in the set.

I still can't believe that the filter manufacturers don't have that information on their website.
