3.
If excessive air is seen in the sight gauge in the fuel
return line, install a second sight gauge at the inlet
to the fuel transfer pump. If a second sight gauge
is not available, move the sight gauge from the fuel
return line and install the sight gauge at the inlet to
the fuel transfer pump. Observe the fuel flow
during engine cranking. Look for air bubbles in the
fuel. If the engine starts, check for air in the fuel at
varying engine speeds.
If excessive air is seen at the inlet to the fuel
transfer pump, air is entering through the suction
side of the fuel system.
To avoid personal injury, always wear eye and
face protection when using pressurized air.
NOTICE
To avoid damage, do not use more than 55 kPa
(8 psi) to pressurize the fuel tank.
4.
Pressurize the fuel tank to 35 kPa (5 psi). Do not
use more than 55 kPa (8 psi) in order to avoid
damage to the fuel tank. Check for leaks in the fuel
lines between the fuel tank and the fuel transfer
pump. Repair any leaks that are found. Check the
fuel pressure in order to ensure that the fuel
transfer pump is operating properly. For
information about checking the fuel pressure, see
Testing and Adjusting, “Fuel System Pressure -
Test”.
5.
If the source of the air is not found, disconnect the
supply line from the fuel tank and connect an
external fuel supply to the inlet of the fuel transfer
pump. If this corrects the problem, repair the fuel
tank or the stand pipe in the fuel tank.

that is most suitable.
1.
Remove the front cover. Refer to Disassembly and
Assembly Manual, “Front Cover - Remove and
Install”.
2.
Use Tooling (A) in order to rotate the crankshaft
until the hole (X) in the camshaft gear (1) aligns
with the hole in the front housing. Refer to
