That would be this one.

Looks like a bad ground.

If the gauge still reads high, try grounding the tank unit electrical terminal to a clean portion of the frame. If this brings the gauge to empty or below, the tank unit is OK, but there is a bad ground between the gas tank and the body or chassis (or less likely, between the tank unit and the gas tank). Either way, find and correct the bad connection or merely run a permanent jumper wire from the frame to one of the screws holding the tank sending unit to the tank.

Porter,

Again, good answer, but to the wrong question. Its the temp gauge in the 49 Cadillac that reads ok then all of a sudden jumps to hot, but the engine is not.

I think it is the gauge, not a groud problem. You?

Try again.

Well, hell have to run all the tests, BTW, he has a 59 not a 49 FWIW.

I thought he said as soon as he turns the key on it buries the needle past full.

Porter ( still sounds like a bad ground to me, which is pretty common and that will bury the needle with the key on ? )

You are the expert here, give me a few wrenches to turn and a spray gun and Im a happy camper (and a few cold ones)

Porter,

Nope it is a new question someone just asked me.... I figured I leave the dirty work to you.

That went right over head, must be the temp gauge.
