3. Screw fitting in until washer pushes o-ring into entrance and
sits flat against port. (Do not tighten! - only do this step hand
tight to compress o-ring into port!)
4. Back fitting out no more than one complete turn to align as
required.
5. Torque nut wrench tight holding backup on fitting (3). This
should expose a recess gap (4) behind the nut which can act
as an indicator that the fitting is assembled correctly. (This is a
feature for a specific version of this fitting only - which screws
into the cylinder head. Other fittings, as the ones which attach
to the hydraulic pump, assemble the same but may not have
the indicator.)

Attention
Avoid screwing in the fitting too far. This can cause
the washer to bend, which will cause the O-ring to
extrude.
Avoid leaving the fitting out too far. This can lead to
the O-ring being cut on the threads of the fitting.
