OEM Sea Water Pressure Switch for ECD gas and some diesel units.

This was used on early EKD gas units and should no longer be used. If your switch is mounted on the service side heat exhanger end cap, ask you dealer about SB-737 and do not use you generator until the update has been completed.

Q: does this switch fit the 7.5 EKD model ??

Asked by: Joe - 7/28/2020

A: 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.

Q: Does this water pressure switch for the 7.3e gas generator and if so, where is it located on the generator?

Asked by: Scott Cooner - 8/19/2021

A: 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.
