Yanmar 2QM15 Bleeding Fuel System - HELP
Have a 1980 Yanmar 2QM15. Has been running great until i got the brilliant idea to drain a little water from the fuel/water separater (Rencor #12?) and got air into the system. As the manual directed, I drained the air from the top "plug" on the fuel filter, then did the 2 connector bolts on the fuel return pipe situated on the top of the cylinders - pumping fuel via the manual handle on the fuel pump till no more bubbles. Then I loosened, individually, the 2 fuel line nipples connected to the injection area and cranked the motor (in decompression mode) but no fuel comes out either one. Afraid to keep cranking, not because of battery going dead (which sounds like it will) but flooding water in engine. Help!! Any thoughts greatly appreciated!!!
