FUEL SYSTEM
Fuel is carried in two integrally sealed sections of the forward, inboard area of wing. Total usable
fuel capacity is 89 U.S. gallons (336.9 liters). There are sump drains at the lowest point in each
tank for taking fuel samples to check for sediment contamination or condensed water accumula-
tion.
The recessed three position handle aft of the console, on the floor, allows pilot to set selector
valve to LEFT tank, RIGHT tank or OFF position.
The gascolator, located at right of selector valve, in the floorboard, is for draining condensed wa-
ter and sediment from lowest point in fuel system before first flight of the day and after each re-
fueling. The gascolator sump can be used to drain the selected fuel tank.
Fuel is delivered, by the engine driven pump, to a throttle body fuel injector where pressure is
regulated and the correct volume of fuel is metered to each cylinder of the engine. Fuel not need-
ed by the engine is returned to the tank from which it is drawn.
The HIGH BOOST pump switch operates the fuel boost pump on high power. The high boost
setting is capable of operating the engine in case of engine driven fuel pump failure or severe fuel
filter blockage. A guard on the ”HIGH BOOST” switch prevents inadvertent operation and must
be lifted for switch operation. High Boost may be used on the ground as an engine starting aid.
Continuous operation should be avoided except in an emergency. Never run the boost pump
without fuel in the system. Refer to SECTIONS III and IV for proper use of the HIGH BOOST
setting.
--CAUTION--
Pushing HIGH BOOST pump switch ON when engine driven pump is operating proper-
ly will cause engine to quit due to excessive rich fuel mixture.
The BOOST PUMP (Low Boost) switch operates the fuel boost pump on low power to provide a
means of suppressing fuel vapor from fuel system during hot day and high altitude conditions.
Low boost may also be used as an engine starting aid. Continuous operation of the low boost is
permitted. Never run the boost pump without fuel in the system. Refer to SECTIONS III and IV for
proper use of the BOOST PUMP setting
--CAUTION--
Pushing LOW BOOST pump switch ON when engine is operating properly at idle con-
ditions will cause engine to run rough or quit due to excessive rich fuel mixture. For
this reason LOW BOOST should normally be turned off except where prescribed in
the normal operating procedures.
Two electric fuel--level transmitters, working in series, in each wing tank operate the appropriate,
left or right, fuel quantity gauges. The master switch actuates the fuel quantity indicator system to
depict an indication of fuel remaining in each tank. Vents in each fuel tank allow for overflow and
pressure equalization.
The optional, visual fuel quantity indicators, in the top of each wing, are to be used for PARTIAL
FUEL LOADING only and NOT for preflight inspection purpose. The Fuel Flow indicating system
indicates the volume of fuel being used, total fuel used or fuel remaining or time remaining (refer
to GARMIN User Manual).
ELECTRICAL SYSTEM
ALTERNATOR & BATTERY
The M20TN has a 28 Volt DC electrical system, powered by a 100--amp alternator which is
mounted on the front of the engine. It is driven by the engine crankshaft through a shear mecha-
nism and charges the main batteries. The alternator is the primary source of aircraft power and is
