hi all. ive just bought a little 22ft yacht with a 8hp yanmar 1gm 10. its no in the water yet as im trying to start it without having to run the battery flat each time .ive tried bleeding it and can only get fuel to the second point with the little finger pump thing but cant get it to the injector that way,so ive been turning over the engine to get it to the injector. the pump lever does'nt get any stiffer or feel like there is any pressure is this normal? i cant see any fuel leeks from joints. when its started it seems to run ok. any ideas what to try?
