Does the high pressure side need to be bled after re-torque head & adjust valves on yanmar 2gm20f?
Only need to bleed if fuel system is openned during repair. If you find it nessesary to bleed to start engine then you may have a air leak in the system. after priming to injector pump on a 2 GM will need to crack injector lines @ injectors and crank engine until u see fuel cone out.
If you've never done this before best to get help the first time. AL
