Re: difference between a 67 C10 tank and a 72 C10 fuel tank

Seems to me a 71 fuel tank cap fits a 72. Could be wrong. But the caps were different, you're right, the 72 cap is "vented". I wonder why really, aren't the tank and charcoal parts the same as a 1971? Perhaps GM just figured the vented cap was simply more better.

1971 EEC cap is actually vented, from what I understand. They just release at a higher PSI than 72.

Other then that, for what worth, 1972 senders and fuel pumps are often different then 1971 and prior. Both have ports for a return line.

With assys, the guide accts for 1000s details such as OEM identifications& part numbers, written in short order. 700+ images include assm, illust., charts, and points of interest. Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
