Fuel Sending Unit
Disassembling and checking a 66-77 Bronco fuel sending unit
Tech article by Dan Thomas (Jeepster)


Sending unit.


Plug.


Back of plug with wire.


Straighten the 3 tabs on the "box" to remove.


There might be varnish built up on this end of the shaft here. Give it a little cleaning and the halfs will seperate easier.


Carefully remove.


Another view.

Inside check for spring and general condition.


In this photo you can see where the contact arm rides on the wire windings. If the tank has sat with gas in it for a long time, the fuel might have turned to varnish and coated the contact arm and windings. A very light rubbing with steel wool should clean it up. Careful not to damage wire.

Check winding for resistance,opens,shorts with a meter. Here the resistance should be ~70 ohms


About 10 ohms here.


Work your way around to all the contact,solder,wire joints to check for continuty, shorts, opens.



Reassemble, bend tabs.

Theres not much to these things. Check the wire for continuty. Work float for ease of movement. New floats and filter can be purchaced.
