Recently Toddster wrote up as part of his Formula restoration the clean up and calibration of the fuel sender unit in the fuel tank. Some details weren't clear to me, so I'll ask my questions here...
1. Where are the contact points on the Torx screws? Is it the flat plate, the very thin wires, or both?
2. How is contact continued from the screws through to main sending wires?
I plan to remove all rust and corrosion from all the parts of the sending unit, then do the calibration. I want to make sure I clean up everything that has corrosion and is preventing a good signal.
On the subject of calibration, how does adjusting the Torx screws affect resistance? Shouldn't there be just one place they can be tightened to? Too tight, they scrape the wires. Too loose, they are an open?
