Welcome to the forum, use different resistors on wire for sending unit. You need to get at the fuel pump/sending unit connector, probably at the fuel tank. The pink wire is for the gage on the dash. The higher the resistance, the higher the gage reading. Seems backwards to me, that is what the info says. 1 ohm of resistance is an empty tank. 44 ohms of resistance is 1/2 tank. 88 ohms of resistance is a full tank. If the gage reacts properly to each resistance value, the problem is either the connector at the tank or the sending unit in the tank. If the gage doesn't act properly, the problem is the wiring circuit to the gage or the gage itself.
I have resistors in my tool box for testing this and that, got them from radio shack, fairly cheap.
