Okay, background. I'm smart but stupid with cars. My fuel gauge on my CJ5 does not work, when it's full it's full when it's empty it's shows 1/4 anything in between is a crapshoot. I've done some research and narrowed it down to be the sending unit... It's the only thing that connects to the gauge right? So I go into Auto Zone and start asking about it and they are looking in the computer and ask me if I have a 4 Cyl. I say no I have a V8 and they say it's not listed and I tell them it came out of a mustang, so they start looking for a mustang sending unit, when I state, the engine is mustang, but the tank is jeep, I believe stock. The "cashier" (I will not call them a tech or any other name after today) tells me it is irrellevant and it is based on the engine. If the sending unit is just a float and a wire WTF... Should just be the stock sending unit right???
Anyways:
1959 Willy's CJ5
Stock Fuel tank(I believe, it's black and is under the drivers seat and is a 10Gallon tank.(maybe a little more than that)
Anyways I walked away without ordering anything, came home and looked up this:

Other than not having the stock Jeep fuel tank is there any reason this will not work?
How Does a Fuel Sending Unit Work? | eHow.com
"The fuel-sending unit is a potentiometer that is adjusted by a float attached to a rod exactly like the float in a toilet bowl. When the fuel in the tank drops in level, the arm with the attached float correspondingly drops, which changes the amount of resistance in the potentiometer. It is a simple mechanism, although all the contacts must be very clean and tight since the whole system relies on resistance metering. A bad ground can cause a difference in resistance that the gauge would indicate."

Thank you.
