Kohler GM30263 OEM Water Pressure Switch

If the switch mount on the exhaust side of the generator, you need GM54744. If it is on the service side, GM30263 is correct, but you should have the service bulletin SB-737 done by a dealer.

If you send your serial number, I can check to see if the SB is open.

GM30263 is the correct pressure switch for your unit.
249930 is showing as the correct t-stat for that serial number.

Accepted Answer

The 7.3E (Carbureted Unit) does not have a water pressure switch.
The 7.3ECD (fuel injected) would have a pressure switch mounted on the heat exchanger.
