Fuel Pump/Hoses (If Equipped)
1. See Figure 125. If removed, orient fuel pump (
A
) as
shown and install two hex flange screws (
B
) to fasten
fuel pump to bracket (
C
). Tighten screws to
35-55 lb-
in
(4.0-6.2 N-m).
2. Inspect each of three preformed hoses (
D
) for cuts,
nicks, cracks, hardness, or general deterioration.
Replace hoses as necessary.
3. Install clamps onto ends of each hose, and proceed
as follows:
NOTE:
After hose installation, squeeze tangs and
move each clamp about
1/8 inch
(3 mm) from end of
hose.
A. Install hose (
E
) to pulse pump fitting (
F
), if
removed. Install other end to crankcase cover
fitting (
G
).
B. Install hose (
H
) to fuel pump fuel inlet fitting (
I
), if
removed.
C. Install hose (
J
) to fuel pump fuel outlet fitting (
K
),
if removed. Connect other end to carburetor fuel
inlet fitting (
L
).
Fuel Tank
1. Inspect the fuel tank for damage and corrosion.
Replace as necessary.
2. Remove fuel cap, if installed.
3. Remove filler neck filter, if equipped. Replace filter if
damaged or if it cannot be adequately cleaned.
4. Check fuel cap and filler neck for proper seals and
vents.
5. Direct the beam of a small flashlight into the fuel tank.
Look for sludge, debris, dirt, and other contaminants.
Thoroughly clean dirty or gummy fuel tanks with
Carburetor Cleaner (Part No. 100042).
6. With the beam of the flashlight directed into the fuel
tank, inspect the external surface area for light that
would indicate the presence of pin holes or small
cracks.
7. Install filler neck filter and fuel cap.
8. See Figure 126. Inspect in-tank fuel filter as follows:
A. Using hex, remove fuel filter fitting (
A
) from fuel
tank.
B. Unthread fuel filter (
B
) and remove O-ring (
C
)
from fuel filter fitting.
C. Inspect fuel filter for dirt and debris. Clean or
replace as necessary.
D. Inspect O-ring for cuts, tears, or general
deterioration. Replace as necessary.
E. Install O-ring onto fuel filter fitting. Verify O-ring is
fully seated in groove.
F. Thread fuel filter into fuel filter fitting.
G. Install fuel filter fitting into fuel tank (
D
). Tighten
fitting to
62-71 lb-in
(7-8 N-m).
9. Inspect hose (
E1
or
E2
) for cuts, nicks, cracks,
hardness, or general deterioration. Replace if
necessary.
NOTE:
Hose (
E2
) is only used on models equipped
with the optional fuel pump.
10. Install hose with clamp (
F
) onto in-tank fuel filter
fitting. Squeeze tangs and move hose clamp about
1/8 inch
(3 mm) from end of hose with tangs pointing
down for best access.
11. If equipped, connect key switch harness connector to
key switch. Install key switch panel (
G
) onto fuel tank
studs.
12. Place fuel tank onto engine.
13. Install hex flange screw (
H
) to fasten fuel tank to
crankcase flange. Tighten screw to
75-95 lb-in
(8.5-10.7 N-m).
NOTE:
For best access to screw, move throttle
