Don't be surprised if the horn honks continuously (or intermittently when you turn the steering wheel) when you reconnect the wire. Disconnecting this wire is a "fix" for the wire's insulation rubbing off up inside the steering column and touching ground to activate the horn relay.

You can test the sending unit by removing it from the tank (most GM vehicles used 5 screws to hold it into the tank, Pontiac used the same gasket [GM part number 1516395] from 1935 thru at least 1960, my '57 GMC pickup used the same gasket ) and using an ohm meter to check from the post where the wire attaches to any metal on the attaching flange. Most GM vehicles of this vintage used 0 ohms empty, 30 ohms full. Attach the ohm meter and slowly move the float from empty (zero ohms) to full (30 ohms). The change in ohms reading should be linear. There shouldn't be any rapid changes in ohms or any readings much over 30 ohms.
