As a low-mechanical skill sailor, with no real diesel knowledge, I have a request for three pieces of advice regarding the Yanmar 2GM10 fuel system:
1. The secondary fuel separator has a metal O-ring with small indentations spaced regularly around it. Is there a special tool needed to loosen the O-ring? Can it be loosened by tapping with a screwdriver and hammer in a clockwise direction?
2. I am proud to have replaced the primary fuel separator filter and O-ring. Perhaps I should have put some diesel fuel around the new O-ring as it may be leaking air. Needless to say, the motor won't start despite an hour of bleeding by loosening the center screw on top of the secondary separator and repeatedly pressing the lever by the fuel pump.
Any suggestions would be welcome. We're coming into cold weather and I can't winterize the cooling system.
3. In the unfortunate event that I'm unable to start the motor, is enough suction created by just cranking the starter motor, several times for less than 10 seconds each time, to suction antifreeze through the motor?
Thanks, everyone, for reading and contemplating my plight. I didn't change fuel filters for two years for fear this would happen. A friend did this in 2012. He made it seem easy.
