Step 8. Connect Fuel Lines

1. Before connection of the main fuel inlet line to the fuel pump, remove all contaminants from
aircraft fuel tanks and fuel lines.
2. Remove unwanted material from the aircraft fuel strainer. Let a minimum of 1 gallon (3.8
liters) of fuel flow through the strainer, aircraft fuel filter and fuel supply line.
3. Make sure that the aircraft manufacturer has a fuel filter installed on the aircraft.
4. Remove protective caps from the main fuel inlet.
5. Connect the main fuel inlet line to the fuel pump. Torque the connections per the aircraft
manufacturer's instructions.
6. Required guidelines for making fuel line connections:
A. Make sure that each fuel line is intact. Not bent or damaged, and does not have any kinks
or dents. The fuel line must be intact.
NOTICE: Refer to Chapter 73-10 in the IO-360-N1A Engine Maintenance Manual for
suggested routing and configuration arrangement diagrams for fuel lines on this
engine. The fuel line configuration diagram is conceptual and for reference only.
Fuel line routing on you engine could have slightly different configurations. Fuel
lines must be examined every 100 hours per the IO-360-N1A Engine Service
Manual.
B. Make sure that the fuel lines are securely connected (to dampen vibration during flight)
with the necessary cushioned clamps and hardware.
C. Fuel lines must be held in place securely using clamps with cushions. Make sure the
clamps are tightly attached to support the fuel line and to prevent movement from
vibration or motion frequencies. Do NOT use plastic tie straps in place of cushioned
clamps.
D. Do not let fuel lines touch the engine or aircraft baffle hardware. There must be a
minimum clearance of 3/16 in. (4.76 mm) between a fuel line and any engine or aircraft
surface.

Step 9. Connect Oil Lines

MAKE SURE THERE ARE NO SHARP BENDS OR KINKS IN THE OIL
LINE ROUTING TO PREVENT INTERRUPTIONS TO OIL FLOW. DO NOT
ROUTE OIL LINES CLOSE TO HEAT SOURCES.
1. Connect the oil line to the airframe-supplied oil cooler.
2. Clean each oil line and install it in the respective areas. Make sure the oil line routing is
smooth, without sharp bends, kinks or helical twists.

REMOVE ANY CONTAMINATION FROM AIRCRAFT FUEL TANKS
AND FUEL LINES. FAILURE TO REMOVE ALL CONTAMINATION
CAN CAUSE PREMATURE FUEL FILTER REPLACEMENT OR
INCORRECT FUEL SYSTEM OPERATION.
DO NOT ROUTE FUEL LINES CLOSE TO HEAT SOURCES. HEAT
CAN CAUSE FUEL VAPORIZATION IN THE FUEL LINES OR CAN
DAMAGE THE FUEL LINE AND CAUSE A FUEL LEAK WHICH
COULD LEAD TO CATASTROPHIC ENGINE FAILURE.
