I had a yanmar mechanic tell me not to vent at the "bleed" screws cause they strip too easy and cause problems. He suggested bleeding the inlet and outlet fittings of the filter. Same thing for the injector pump (forward, next in line after the filter). I had a situation during the delivery from Brooklyn NY to Solomons, MD in the C&D Canal where the bleed screw popped out of the inlet fitting for the injector pump. A little JB Weld and an hour later we were back under motor.
You should also get VERY familiar with bleeding the fuel system of air. I recently, accidentally, ran out of gas while motoring in 6-8 foot breakers and 20-25 kts of wind. We got the sails up and could have continued indefinitely except that the next port was 4nm up a shallow and narrow channel and the sun was setting. After having 10 gallons of diesel delivered to the middle of the Chesapeake Bay (Bay Marker #42), we started the engine and proceeded to take the sails down. At almost the same time the engine started sputtering and then died. Various restarts were attempted but it was pretty quickly determined that there was air in the lines. Fortunately I was very familiar with venting. From the time I left the topsides to investigate the dead engine to being back under power was probably less than 10 minutes. And that obviously includes all the time diagnosing/restarting, and time finding tools. A new gas gage made it to the top of the projects list!
