Tests
3. Disconnect pilot pressure line (D) at pilot filter. Install
tee (B) and male quick coupler. Connect the digital
pressure and temperature analyzer, and transducer, or
a gauge (C).
Pressure can also be checked at the test port in fitting
at the pilot pump (F) outlet port. Use adapter (G) in
test port.
NOTE: Because the plug is installed dry at the factory,
the plug can be difficult to remove.
