BEFORE TROUBLE SHOOTING THE ENGINE
Check Fuel Tank Filter
Equipment Necessary: 12-lnch Stiff Wire and
Gasoline
Inside the fuel tank on the end of the fuel line is a
brass screened fuel filter. The filter must be clean
to allow the fuel line to transmit the maximum
volume of fuel. If fuel filter is obstructed, fuel flow
will be restricted - cleaning is required .
1. Form a hook on the end of a piece of stiff
wire.
2. Remove the fuel tank cap, insert hook
through the filler hole and pull fuel line and
filter from within the fuel tank.
3. Examine the condition of the fuel filter. If
filter is obstructed, wash in a container of
clean gasoline. If brass screen or spring is
damaged, filter is to be replaced.
e
CAUTION
e
DON OT clean the fuel filter by scraping with
a wire brush or similar tool, as this may damage
the screen, allowing foreign particles to enter
th e fuel line. As a result, carburetor
malfunctions may occur. Always replace a
damaged fuel filter.
4. When the fuel filter is clean, install in the end
of the fuel line. Insert fuel line and filter into
the fuel tank, making sure that the filter
touches the bottom of the fuel tank.
5. I nstall the fuel level gauge cap.
Check In-Line Fuel Filter
Equipment Necessary: Gasoline
The fuel line also incorporates an in-line fuel filter,
just before the engine mounted fuel pump. The
filter must be clean to allow the fuel line to
transmit the maximum volume of fuel. If fuel filter
is obstructed, fuel flow will be restricted -
cleaning is required.
1. Remove the fuel filter from the fuel line.

After fi Iter is removed, position the fuel line
higher than the fuel level in the fuel tank so
that drainage does not occur.
2. The in-line fuel filter is a unitized component
and does not have a replaceable filtering
element. Therefore, the only cleaning that is
to be performed is a back-flush of the filter,
using gasoline.
3. When the fuel filter is clean, install in the fuel
line.
4. Check fuel line, return line and impulse line
for proper connection on the fittings. If lines
are cracked or deteriorated, replacement is
necessary.
Check Fuel Pump Filter
Equipment Necessary: Screwdriver and Kerosene
The screened filter in the fuel pump bowl is to be
clean to allow the maximum volume of fuel to be
pumped to the carburetor. If screened filter is
obstructed, fuel flow will be restricted - cleaning
is necessary.
1. Remove the fuel line running from the fuel
tank to the fuel pump fitting. Place the fuel
line higher than the fuel level in the fuel tank
to prevent drainage.
2. Remove the screw and lockwasher that se-
cures the fuel pump bowl, using a screwdriver,
Fig. 11-12.

3. Unscrew the cover and remove the screened
filter and gasket.
4. If the screen is obstructed or dirty, flush with
kerosene and dry thoroughly before installing.
