Im a dumbass and i dropped the fuel pressure check valve cover for my ecotec some where in the engine bay. I found a couple online, but they want $15 to ship the damn thing. Autozone doesnt have one... can anyone think of a good place to get one? I think its a -4an shrader cap.
i wouldn't be too worried about it, but if it really bothers you, grab one from a junkyard. i cant imagine that they would charge you much for it.
Use a tire stem cap
On the inside my car looks like a fighter jet.
tire stem caps are smaller.
