Default Fuel Tank Question on 1972 base model

The fuel sending unit pipe on my 1972 base model appears to be hitting the upper spare tire cover. When the lower tub is cinched up with the tire in place, it appears to be putting pressure on the fuel sending unit. I am afraid that the pipe will break some day. The previous owner put a new fuel tank in and although the filler neck appears to be centered in the rear deck, there are a couple of wood shims jammed in between the rear of the fuel tank and the rear frame member. I am sure this is some "customization." For now, I have put in longer bolts on the spare tire lock bolt assembly and shimmed the mounting bracket down from the frame by 3/4 of an inch with some washers. Wondering if anyone else has ever come across this issue? or have any ideas?

Hi DC,
Here's what I'd consider to be a fairly typical placement and installation of an original tank and sending unit.
It's from a 71 but I believe your 72 is similar if not the same.
The correct tub lid and tub are shaped to clear the sending unit with the correct tank installed in the correct location.
How does this compare to what you're seeing?
Regards,
Alan

Hi Alan. Thanks for your reply and the picture. The rear of my tank appears to be hanging lower than yours (closer to the ground). I am not sure that I can push mine above that rear frame as shown in your picture. I wonder if the previous owner put the wrong tank in.

Hi DC,
The rear several inches of the tank definitely seats on the rear crossmember.
In fact the perimeter flange on the tank is about even with the rear most face of the rear crossmember.

In this picture you can also see how the front of the tank seats on the tank crossmember that bolts in place to the 2 rear frame rails.

I put 1/4 turn shut off valves on my gas tanks. About $5 and available from any lumberyard or hardware store. Sure comes in handy to be able to shut the gas off when replacing hoses and such.

Hi DC,
I couldn't find this one yesterday…. if you happen to return perhaps it'll be of some help.
