1952-59 Ford 1956 wagon gas tank float assembly

Is there a way to test this unit to be sure it works?

 

There's got to be. Forget what I typed a few minutes ago...my brain isn't working. Didn't even make sense to me.
There should be a way to hook up 12 volts and check the output in ohms as you move the float thru the rheostat's range.

 

The manual does not have a way to test without the gauge, but with some research there is an old post here I read which explained the bimetallic sending unit in great detail. Maybe that would help find out if there is a way to test it without the gauge.

 

I have the gauge. Not sure how to wire that though.

 

Here's a link to some great info on senders and how they work. It also tells you HOW TO BENCH TEST YOUR SENDING UNIT

Tanks inc is where I got my sending unit. I had the correct one supplied with my gauge kit, but it was no where made as well as the tanks inc unit. I also got my in tank pump and recessed mounting plate from them

 

If it's out of the tank you can check continuity by raising the float up and down. HRP

 

Did you get it checked out?

 

I have the manual, if you need me to send pics of the pages PM me.

 

The gauge itself is simple to hook up. Do you have the schematic for the car? If not you can find one online, the best I could dig up was for a '57 Ford.

I used an aftermarket harness in my car, but ran into zero problems with the gas gauge.
