Does anyone know whether there were differences in fuel tanks during the manufacture run of the 240z? Specifically, are the 72 and 73 tanks the same?

According to the parts catalog, yes, they are the same.

For forum archive purposes I just wanted to follow up on what I discovered. The reason I asked this question is that I am refreshing my 5/72 orange 240 and I am going to refresh the fuel tank. For quite some time I have owned a still boxed up 73 fuel tank that I purchased on Ebay several years ago. I wanted to know so that I could restore the 73 tank and then swap.

I have since brought the 73 tank out of storage and opened it up. Luckily, it is in great shape. It appears to be identical to my 72 tank except that it has a fuel pump mounting bracket at the tank seams on the engine side of the tank. Here are photos of the two tanks.

Thanks,
