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

Yep, what alpatn said. If you didn't disconnect any fuel lines you shouldn't have to bleed anything.

If you are just learning about your engine, it might be an opportunity to do it as a practice run, dry or full monty. Less thinking to do after filter change on a lee shore.
