FUEL AND AIR LINE REPLACEMENT
AND PROPER ROUTING
1. Open upper shroud (see Shroud and Up-
per Shell, page 12).
2. Inspect fuel and air line hoses for cracks
and/or holes. If fuel line hose is damaged,
disconnect from nozzle adapter (see Fig-
ure 24, page 15 or Figure 27) and from
fuel filter (see Fuel Filter, page 14). If air
line hose is damaged, disconnect from
nozzle adapter (see Figure 24, page 15 or
Figure 27, page 16) and from barb fitting
on pump end cover (see Figure 29).
3. Install new air and/or fuel line. Attach one
end of air line hose to barb fitting on pump
end cover (see Figure 29) and the other
end to nozzle adapter (see Figure 24,
page 15 or Figure 27, page 16). Attach
one end of fuel line hose to fuel filter (see
Fuel Line (do not allow fuel
line to droop and trap fuel)

0.101 mm (0.003"/0.004") if needed (see
Figure 32, page 18).
Note: Rotate rotor one full turn to ensure
the gap is 0.076/0.101 mm (0.003"/0.004")
