I just did the intake leak repair and put it all back together but lost one of the rectangular white rubber seals that fits into the fuel injector electrical snap in hook up. Are these water proof seals? Where can I get one?

 

Might have to order them from a gm dealer, I ran my car without one for the 2 years I had it...no probs, but I would get a new one if I were you...

 

If I remember the instructions, they were call back-up seals. When you buy them, they will be black. Don't ask me why.
