That looks great... like brand new! :thumbsup:

Did you use the pick-up screen that came with your sending unit?

I couldn't get mine to fit, so I didn't use it. :shrug:
You've really got to force it in there on some tanks. The screen tube has some give when forced, and that way it sits tight on the bottom which might help get the most out of your tank.

I've got to drop my tank again soon, for another project... I'll try putting it on again. I've also got a brass float to install.

Here's how the USPS/FedEx delivered my sending unit yesterday
A big box

with a little box in it!

Here's what came in the kit

Got this little brass dandy so I don't have the float half full happen again

Ohm'd out at full, half and empty. Goo to go!

Can you show me exactly where your attaching your leads, on the sending unit? I have a multimeter but mainly use it to measure volts on batteries.

I have that same sending unit and brass float sitting on a shelf, and would like to make sure it's good before I go dropping the tank to replace it.

Set your multimeter to the lowest resistance setting (usually 200 ohms).

Attach one lead to the +threaded post, and the other to the -spade. Resistance should range between 10 and 75 or so.

Nice work!!

Great Pics!!

I forget; does the ground attach to the sender? Or a secondary ground?
There should be a ground jumper from the frame near the tank that attaches to the sending unit.
The post on the sending unit connects to the wire running back to the gauge.

Connect as stated, the sending unit is a variable resistor so it doesn't matter which lead connects to which position.
Here are the specs per the FSM:

What Walker said. Civilian jeep has a great troubleshooting logic for all the gauges. Read up on it and get busy with your multimeter checking voltages and resistance on the gauge and sender.
WORTH SAYING: Check that your gauge cluster and dash have a good ground, preferably straight to the battery. Also, I ran the tank sending unit ground straight to the rear crossmember with an crimp terminal. I used "oxguard" anti-oxidation on this connections.
