electrical and ignition Gas Tank Immersion tube

Somebody cut it off and plugged it. The fuel pump is under the car. My fuel gauge is/was also indicating "Full" all the time. 

What's up with this?

 

I checked the Service Manual and it's supposed to go to the fuel pump on the trunk wall. Was relocating the pump a common mod? I couldn't find any screw holes or indication that there was a pump in there at anytime.

 

Car's a 74 Tii.

Thanks

When owning one of these old cars with hacks, it will pay to learn how to trouble shoot some common problems.

 

Looks like the level sender had been replaced with one from a carb version.  The plugged hose from it is not the problem.   If you gauge reds full all the time, either there is a short in the lead from the sender to the gauge or the gauge ground is open.

Try removing the wire that goes to the gauge (the one with the insulated connector).  If the gauge level drops to empty, the wire and gauge are ok.  If not you have either the short in the wire to the gauge or gauge ground loss.

Check the resistance to ground the level sender.  Full tank is near zero ohms.  Empty tank, 70-75ohms.

There many other threads on here that discuss fixing gauge grounds and sender problems, so I'm not going into that.
