Yanmar 2QM15 Bleeding Fuel System - HELP
I found the easiest way to take care of the bleeding of the fuel system is to install a pump between the tank and the Racor filter.
I used a squeese bulb for a outboard motor on mine. Then you just pump the fuel from the tank and vent the air at each vent site in order. Start with the primary filter, then the final filter.
I never had to bleed the injector lines.
The engine should start at full throttle and will probably run a litle uneven for the first few min.
You should probably close the sea water inlet seacock until the engine is runnig to prevent flooding the engine
