This is why a fuel sender dies. (with pic)

Aren’t the OE ones wrapped differently than the reproductions? Something about the resistance varying over the throw of the pickup to account for the non-linear way the volume of the tank drops because of the spare tire cut out?

Also pretty sure there’s a guy back east that rebuilds the OE senders, they’d have to be better quality than the reproductions. I’ve seen his contact info on here somewhere.

Although that said the one in my Duster has been working fine. It’s not accurate to the amount of fuel, ie, 1/2 a tank doesn’t mean 1/2 a tank. But it’s consistent, and I drive it enough to know how what the gauge shows corresponds to what’s left in the tank. Plus it’s a 3/8” sender, although I’m sure there’s some way to pair the OE guts with a larger tube...
