Connect the aircraft manifold pressure line to the pressure port on the PT-30ABS Pressure Transducer. A
flare or barb fitting may be used to connect these lines. Care should be taken not to put excess pressure on
the flexible line leading to the pressure transducer.
Make sure there are no kinks in the flexible
pressure lines.
Note: Many certified aircraft have a very small hole in the manifold pressure line to create airflow back to
the intake manifold. This small flow of air keeps fuel from working its way into the manifold pressure
gauge (or transducer), which can cause damage to the transducer over time.
Note: The PT-30ABS can measure manifold pressure up to 36.0" Hg. For manifold pressures above 36.0"
Hg. use the PT-60ABS pressure transducer.

Mount the PT-05Diff Pressure Transducer on the inside firewall or in the equipment bay under the aircraft
instrument panel. Use the holes in the bottom plate to mount the PT-05Diff. Only two mounting holes are
required.
Connect the aircraft gyro vacuum line to the port tagged "Vac" on the PT-05Diff. Connect the port tagged
"Press" to the aircraft overboard pressure line. A flare or barb fitting may be used to connect these lines.
Care should be taken not to put excess pressure on the flexible line leading to the pressure transducer.
Make sure there are no kinks in the flexible pressure lines.
The PT-30ABS, Pres-
sure Transducer is used
on most engines for
Manifold Pressure (0 to
36" Hg.).
