The P-300M is a PMA’d fuel level sensor designed by E.I. to replace a resistive sensor. The P-300M works off magnetics and is a much more accurate and reliable sensor. It is not affected by vibration, corrosion, wear, varnish build up, poor wiper tension or any of the many other problems affecting resistive sensors.
The P-300M work only with E.I. instruments. The float travel must be specified. If an existing sensor is to be replaced, ship you old sensor to E.I.
