[DeTomaso] One more question!

[Paul Timko]

Disconnect the wire from the sender.  It could be the unit on the 
pressure tank.  Turn the key on, no need to start the car.  Touch the 
wire to bare metal somewhere.  It should read full scale.  I would just 
touch the wire to ground, I wouldn't leave it there.  The engine is 
ground if you can't find a better place.

At some point in the future you should consider moving the temperature 
sender from the pressure tank to its normal spot on the front of th 
engine block just below the thermostat.
