Does anyone on the list have a dead fuel sending unit for sale, cheap? The reason I want one is to try some expermentation with a Bosch unit I found in a humpback Saab. I need to compare the resistance readings, float values, and measure float movement etc. to try and compare the differences between the 2 units. If I can't make this work, I'll pop for the Tankzilla, but I want to try. (I fried mine testing it with a battery charger). Thanks, Jim Coleman Waco, TX
