The exterior of the gas tank has been treated with Rustoleum Rust Reformer and then painted with gloss black Rustoleum paint. The inside was first blasted with a pressure washer and then using some household cleaner, water and 6 ft of metal chain I shook the hell out of that thing for as long as I could. I plugged the holes with some special gas tank repair putty too. It's still far from perfect but should all last me a bit longer.
The new sender unit has arrived and I hooked it up to the gauge (without re-installing the tank) to see if everything was working correctly. I set the armature of the sender to indicate a full tank (minimum resistance) and checked the gauge. It read 1/2 a tank. I set the armature to 1/2 tank position and the gauge read Empty. Setting the sender unit to empty (and maximum resistance) the gauge hardly moves at all and is well below the Empty marker.
I've bid on a new instrument cluster on a well know online tat bazaar.
