U302 Fuel Gauge ohm Range

[ejb17]

I need a new fuel level sender for the tank. It has fallen apart but the gauge does test fine. Does anyone know what ohm range sending unit I will need to match the gauge?

Will be 2-300 ohms. I have one here I want to do same.

I am guessing you mean 0 ohm empty - 30 ohm full? Seems to be what a lot of pre-1964 vehicles used.

300 ohms empty. 133 1/2 47 3/4

I tried a "modern" 240 empty to 33 full and it is a no go. Doesn't seem to be the correct range for the stock gauge. Looked for a 300 empty sender and google came up empty.

All same sender on all MM's. Stewart Warner. Used a M670 diesel in my 670 gas. Just arm is bent different.

I have found a Napa one that works okay. Don't quite read all the way full. I will try to look for the part number tomorrow.

Napa part number 701-1642 is what I have used and it works okay. It won't quite read full from what I remember.
