Yes. It involves three 15 ohm resistors, some wire and soldering skills.
Wouldn't you just connect the resistors across the gauge terminal and ground? A 15 ohm should make the gauge go to about mid scale, a 30 ohm should indicate full, and shorting the terminal to ground should show empty. Aren't you just simulating the sender?
[on edit] Looks like Jon gave a better and more complete explanation than I did.
