What year is this fuel tank?

[Rust Bucket]

I am getting conflicting information from different sources. My 75 CJ5 needs a new fuel tank. I ordered one from a local vendor and when it arrived I noticed the fill tube was 3" diameter and 5" long. My current tank has a 1 1/4" by 1 1/2" long. Can someone tell me what year fuel tank to order? Attached is the current tank.

That tank looks like a 78 and up tank. I'll see if I can find a pic to post.

I agree, my intermediate tank looks nothing like that...

78 and up looks like the one on the bottom in the pic. 1 in. diameter 1 in filler neck. Click to enlarge

Cool, thanks Pete. Now I need to decide if I'm going to replace it with another '78 tank or go back to the original. I already bought the 1" tubes for this tank, so I guess there's no reason to go OEM.
