The 1990 primary injector has an "O" ring that sits inside the housing body. The "O" ring fits around the injector body providing the seal. These are about the size of a quarter and no longer available at GM. If you need some let me know I can tell you where to buy them, cost is about a dollar each. These are made of Viton material, same as the original. GM price on these was $25.00 each.
