Sending units, whether for pressure, temperature, whatever are generally
intended for use with a specific gauge. 'Most any sender is just a
temperature- (or pressure-) sensitive resistor, designed to provide a
specific range of resistance values (and therefore gauge needle deflection)
for a specific range of conditions. If one were to substitute a sensor
designed to drive a 0-100 psi gauge for one designed to register from 0-60,
for example, the gauge would indicate low or high, depending on the design of
the sensor (sending unit).
Aftermarket senders and gauges are specified as sets for this reason, as is
the OE stuff. Ya cain't swap stuff around simply because it fits.
