JC Whitney sending unit
Dan and others,
I'm sorry to hear that the JC Whitney unit did not work for you. The unit I bought off the JC Whitney web site was:
Adjustable Fuel Level Float, for General Motors Vehicles, 0-90 ohm resistance, PN: ZX132950R Each $17.99.
I removed the white plastic rehostat from it and put it on my hanger after drilling out the rivets that held on the original bad one, then formed the new float arm to fit. The rehostat had the exact same mounting hole locations so I was able to easily adapt it onto my hanger.
As I remember, the new unit was packed in a white box and it was made in the US. Maybe they found a cheaper supplier and thats why it does not fit.
The rehostat has a metal cover, you could probably bend back the 3 tabs to get it off and clean up the windings and the wiper contact point and then verify that you get 0 - 90 ohms across it as you lift & lower the float arm. I hope that works for you.
Bob
