i've got one injector that is missing the little brown cap on the end that sits in the manifold. the stock injectors don't have these on them, so i couldn't just pull one off and use it. i work at advance auto parts, and we don't have them, napa did not have them, car quest did not have them, and the GM dealership said they can't get just that piece.
if anybody knows where to find just one of these, or a whole set, or has a part number, that would be great.

this is the link to the ebay auction showing the injectors, the injector on the far right is the one missing the piece, it's obvious what i'm talking about in this picture if not clear already
