1976 Scamp fuel gauge problems

That sender should do nicely. Something else to check. There is a short piece of rubber hose that connects between the fuel line running to the front of the car and the line coming out of the tank at the sender. There is supposed to be a flat metal strap that clips to the fuel lines on either side of the rubber hose. If this strap is missing/rusted out your fuel gauge won't work since it is grounded through the fuel line. If your strap is missing and you can't find a replacement, you can bridge the hose with a couple of hose clamps and a piece of wire...

Okay, I'll go ahead and purchase that sender then. I did notice the strap that you speak of and I was wondering what that was. Thanks for letting me know that. From what I understand, there's a member on here that possibly has the cluster for this car and I'm gonna try to buy that. But then again, there's a lot of stuff that I both need and want to buy for it. It's a factory a/c car, but all the under hood stuff was removed and put in the trunk and no one knows why. I also found the vacuum amplifier in a plastic bag in the trunk along with the original bias-ply spare, bumper jack, about 6 burned up ignition modules and 5 burned up voltage regulators. It also seems like the wiring has been cut a few times for various add-on stuff like the newish radio and an alarm that doesn't work, which is probably why the oil light is stuck on. I also found out there is no fuse in the number one spot in the fuse panel. Is there supposed to be one there? There are (I think) two other spots with no fuses, but those don't tabs in them to hold the fuse whereas this one does.
