filter)
The load-sense return line (also
teed into the in-line filter) has an
orifice between the fittings.
Ensure the orifice is located in a
manner that it will not restrict
the flow of the new tank line
(H78). In Figure 19, illustration A
shows the original plumbing of
the load sense return and orifice.
B and C show two options for
installation of the tee fitting.
