fuel gauge doesn't reading 0 and it's full
The fuel gauge in my 2-liter has never worked, how can i tell if it's the gauge or the sender....(or the large hole in the gas tank)

At a full tank of gas , I believe when the wires are off of the terminals at the gas tank sender, its 26 ohms between the tank terminals.
If you need a scan of the manual's section on the fuel gauge send me a PM with your e-mail address.
It looks as if Alexi is getting you on the right track for the dash end of the diagnostics with his (VoltReg) question.

Hmmm, I'm pretty sure the roadster sender is a 0 - 90 ohm sender.
1) Open the trunk and unscrew the square inspection plate in the center of the trunk floor.
2) Remove the inspection plate to uncover the fuel level sender.
3) Mark the two wires going to the sender so you don't get them mixed up. Disconnect them.
4) There's a retaining ring around the outside of the sender. Unscrew it. Pull the sender out of the tank.
5) Connect a volt-ohm meter to the two electrical terminals on the sender. Measure resistance with the sender arm and float hanging all the way down. Should be close to 0 ohms. Slowly move the sender float and arm up and watch the resistance change. Should end up close to 90 ohms when it's all the way up.
6) If the sender checks out good, re-install it. Before connecting up the wires, clean the posts really well with a wire brush. Get a tiny file from the hardware store and use it to clean out the electrical connectors on the ends of the wires.
My fuel gauge was not working on my car either. It ended up simply being corrosion on those connectors. Once cleaned up, it worked fine!

Fuel gage
the rest of the instruments are working, i'm pretty sure the temp gauge works,
i'll pull the sender, slapping a 50 ohm resistor across those terminals out to give me a reading too..
thanks for your help...
This car has been run maybe 100 miles in the last 10 years, and now it's finally tuned and running very well, so as we start driving it, i'm sure i'lll be back with more questions..
like where's the Air conditioning in this thing, the only way i have found to cool off is to take the top down and drive really fast...
