    So the fuel sender is putting out 40 M ohms.

    Does this mean the sender is bad? Or just stuck?

    Fuel tank was empty and leaning up sideways for a week while I was changing the lead springs and rear axle.

    Could be the contacts have oxidized and maybe with fresh fuel in the tank on the contacts the sender will begin reading right.

    With the tank out now it might not be a big deal to take the sender out and see what's going on.

    I agree with Jim. If the sender is original on a car this old it's either bad or will be soon.

    It's the original sender. I just ordered a stainless steel replacement. Hate taking the tank out since I always have trouble getting it back in with just a floor jack but hopefully this will be the last time for that after I replace it lmao

    Resistance reading that high indicates an open circuit. Your ground might be corroded.
