Fuel System - Piper CHEROKEE 180 C Owner's Handbook Manual

PIPER CHEROKEE 180 "C" SECTION II
mounted on the right side of the pedestal below the throttle quadrant and
permits directional trim as needed in flight.
The flaps are manually operated, balanced for light operating forces and
spring-loaded to return to the up position. A past center lock incorporated in
the actuating linkage holds the flap when it is in the up position so that it may
be used as a step on the right side. The flap will not support a step load except
when in the full up position, so it must be completely retracted when used as a
step. The flaps have three extended positions: 10, 25 and 40 degrees.

FUEL SYSTEM

Fuel is stored in two 25 gallon tanks which are secured to the leading edge
structure of each wing by screws and nut plates. This allows easy removal for
service or inspection.
The standard quantity of fuel is 50 gallons for the Cherokee 180. Each tank is
fitted with a filler neck indicator, which extends some distance into the tanks.
Filling the fuel tanks to the bottom of the indicator will provide approximately
36 gallons of fuel (18 gal per tank).
An auxiliary electric fuel pump is provided in case of failure of the engine-
driven pump. The electric pump should be on for all take-offs and landings,
and when switching tanks. The pump switch is located in the switch panel
above the throttle quadrant. Each tank has an individual quick drain located at
the bottom, inboard rear corner, and should be drained to check for water
before each flight. The fuel strainer, which is also equipped with a quick drain,
is located on the front lower left corner of the firewall. This strainer should be
drained regularly to check for water or sediment accumulation.
Fuel quantity and pressure are indicated on gauges located in a cluster on the
left side of the instrument panel.
