PUMP COMPONENTS (AP6/AP8)
15. Air Separator Vacuum Gauge – 0 to 30 in. Hg
(0~762 mm Hg) vacuum gauge that indicates vacuum
pressure. Under normal operating conditions this gauge
should read between 24~25 in. Hg (610~635 mm Hg).
16. Control Box – Displays vital engine parameters via
gauges and LEDs. Included gauges are tachometer,
temperature, battery voltage, hour meter, oil pressure.
Engine fault LEDs include battery discharge, low oil
pressure, high temperature, alternator failure and
V-belt failure.
17. Document Box – Contains all documentation relating
to the pump or engine.
18. Couplers – Trailer is available with either a 2-5/16 inch
ball coupler or a 3-inch pintel coupler.

in conjunction with the air separator chamber for the
automatic priming process.
25. Fuel Tanks – The AP6 pump is available with a 50
gallon (190 liters) fuel tank, while the AP8 is equipped
with a 55 gallon fuel tank (208 liters). Both fuel tanks
