Fuel Sending Unit
I've installed an under bed tank in my 1966 F100. Now I need a sending unit that is compatible with my OEM fuel gauge. The sending unit in the tank right now has the wrong resistance range. I think I've discovered that the correct range is 73 ohms empty and 10 ohms full. Anyone found something that works?

Ford used the King-Seely gauge system for decades at least up until 1980. All the gauges work on the same ohms only the gauge faces are different to depict what they are measuring. Just find a car or truck tank that is the same depth as your tank and use that sender.

I found this called MeterMatch... https://www.tanksinc.com/index.cfm/p...rod/prd748.htm
It can translate any sending unit to the parameters needed. Going with it.

I might be able to hit both ends of the scale using a resistor network if my sending unit wasn't backwards from the OEM one. The issue with this sending unit is that it's at max resistance when full. F100 gauge is max requires sending unit to be at max resistance when empty.

I think these will work, the 73-10 ohm version. Please verify before trusting my word. I am planning on building an in bed tank pretty soon. I ordered one of those
senders. They use lidar to sense how much fuel there is. You can set the ohms for empty to full. I'll probably test it today to see if it actually works with the stock gauge. I've read mixed statements on if they work or not. I think this is the second version which may have expanded support for older style gauges. I have no idea what the mount size of the sending unit is on the stock or under bed tanks.

I'll be interested to hear how this works out. Odd that when I talked to the tech guy at tanksinc, he didn't mention this. He pointed me to the electronic gizmo that translates the sender I have. When (if?) I get it working, I'll report on it here. thanks

Can confirm the holley unit works on my truck with stock gauge. You have to program it using the 3 little buttons. Looks like it will fit fine on the in cab tank. Downsides are you have to run keyed power to it and the it takes a little while to program it. You have to set the gauge empty, half, and full. And then you have to set the distance empty and full. It wasn't bad, but could be confusing if you're not tech savy.

Black33ford, let us know how things work out. I just installed the Mustang (I went with a 70 22 gal) tank and FI Tech in tank fuel pump. I really don’t want to cut another hole for a sending unit that works with aftermarket gauges. Thanks.
