Going to drop my tank this weekend and give it a thorough cleaning. Had a batch of bad fuel...gunked up a couple of filters, so my sock is likely in as bad of shape.

Does anyone have a part number and source for an aftermarket fuel tank Sock? Called GM and they dont carry (or so they claim), but were happy to sell me a $400 sending unit with it included. Napa didnt either.

Thanks in advance.
