Identifying an Original 1972 truck gas tank

[72 Super]

I would like to find an original 1972 gas tank for my truck. I believe the filler neck is smaller in diameter correct? Is there anything else to look for when trying to identify one?


Ours was replaced years ago with one from a 1970 I believe.

Thanks in advance,
Ray

It should have a 1.5" diam fuel neck and a Fuel vapor return line. the earlier ones had the vapor line tied into the neck and 2" neck if I remember correct.

71-72 gastanks both had the extra fitting to vent to the hiloop in the pass door post that went to the charcoal cannister

I know my truck has the return line as it is still in the cab.

My truck does have the return line as it is still in the cab and plugged down by the fuel pump.

I am on the look out for clean 72 Gas tank.

Thanks,
