Howzzzit you called it!

I ordered my tank through Rock Auto and I searched high and low but couldn’t find a phone number to call. Their website says they communicate through email only. This may give me pause to order from them in the future.

I ended up calling spectra who manufactured the tank. They told me a Stant 10704 should fit my tank. I found one that worked at a local parts store but it is a black locking cap. It will work for now but my son wants a plain chrome one like before. I will look around to see if I can find one online.

On the bright side the tank fit great. My son and I had the old tank out and the new tank installed in about an hour. Everything lined up great. I was surprised how easy and fast of a job it was. I saw stories of others where the filler neck was too long and they had to slot the holes in the tank to get everything lined up. I didn’t have any issues at all. The tank feels like a quality build. The steel felt thick not flimsy at all. Anyone needing to replace their fuel tank for a 1972 C10 with EEC I highly recommend the Spectra GM49B tank. Just make sure you have a Stant 10704 gas cap handy.
