Fellow Sailors. I have a Westerbeke W20B on a Cat 270. I am getting ready to check and replace the fuel filters on the engine and water separator. To prime the system after replacing the filters the service manual says to turn on the ignition switch for about 1 minute and allow the electric fuel pump to prime the system. Nothing else. Is that all there is I need to do? Am I missing something? Also any additional wisdom on the subject will be greatly appreciated. Thanks...Steve
