Gas Tank Questions

Totally agree with one caveat, the accuracy of the sending units. I believe even Spectra uses a linear wire wrap on the resistor, so with the A-body tank not having a consistent cross section there will be a little inaccuracy there.




Yeah I don’t think it’s really intentional. Just the result of varying thicknesses of the tanks and the lock rings. But I doubt anyone stresses out about getting them perfect since you can adjust them.
My argument there is, while they may not be 100% exact, even the stock ones are an approximation. We're talkin about technology that's close to if not 100 years old and it ain't changed much. What's important to me is, when the gauge reads empty. LOL
