Fuel Guage Goes Up Then Partly Fades -- 72 Swinger

If you get 5 or 10 x 1 ohm also you can mix and match to get all the happy resistances.

I was going to make a fancy decade resister box, but ended up just soldering the ends of the 10 ohms in series and the 1 ohm the same with 3 jumper wires I can make any resistance from 1 ohm to 110 ohm
I bought some 24 inch 18 guage wire with alagator clips on the ends. Works great.

Also very handy to have the wire with clips.

Bypassing ballast resister, jump starting the ignition etc

Remember this is the values right out of the 67 FSM

Empty is 73 +/- 12 ohms (61 to 85)
Full is 9.6 +/- 1 ohm (8.6 to 10.6)

I have posted a graph the I made with 3 different senders and what MY Fuel gauge wants in terms of resistance for E 1/4 1/2 3/4 and F
