There are two very popular styles of fuel gauge sender. One, the ohms increases with fuel tank level, the other style the ohms decreases with a fill up. You will neeed to find out which your sender is by manually moving the float while measuring the ohms, then find out what type of sender your gauge is for.

Ammeter.... run a 10 gauge wire from the hot lug of the starter solenoid (ford type) to the fusebox. This is the only power feed to the fusebox, put the ammeter inline on this wire. If your ammeter is running backwards, swap which terminal the wires are on at the ammeter, (the "in" and "out" terminals)
