Default F.A.S.T. 102 lower injector o-rings?

Does anyone know of a injector o-ring you can go to the parts store and get for the fast 102 lower intake? Trying to avoid ordering and want them today. I thought I heard mustang o-rings maybe?

7mmx4mm, tough to find state side. I had to buy a pack of 100 to couple with my rail adapters, so I have some spares if you're interested. Say, 15 bucks shipped?

This would be a long shot, but if you are close by to one, hit up a Polaris dealer and check for part number 5412891 or 1500198. Those may be the ones you need.

You can use a stock LS1 o-ring, then go to harbor freight and buy the green O-rings, that are heat treated and chemical resistant, the stronger ones.

I took the stock one and used a green smaller one from harbor freight and placed it above the stock one on the bottom of the injector. Even though the stock o ring is smaller around the injector site of the intake, The Harbor freight o ring pushes on it so that it will not move. No leaks, no problems. Plus mine is a boosted car. It works well.
