Nothing strange - take out old injectors - take out the old gaskets - have new Gaskets ready - insert new injectors. replace fuel lines. Bleed system. Run the engine at high RPM check for any fuel leeks - rectify if necessary.
Number 6 on image are the gaskets. If you need Yanmar's service instructions send me a PM with your email address .
