Fuel Guage Goes Up Then Partly Fades -- 72 Swinger

Good info -- Thanks! If I had only known how much the Spectras suck, I'd have never thrown out my (still working) original when I changed the tank. Live and learn. Now I've got a NOS 2421493 but before I put it in, I'm trying to make sure everything else in the system is in working order -- hence the resistor test.

I'll definitely solder the resistors together in the configurations listed above with a clip on one end for ground and a screw that fits the sender wire fitting on the other, test them with a multimeter to make sure they are close, then test the gauge. I'll then put them in a box and use them in another 20 years when I have to go through this again.
