The fuel filter
The fuel filter is located in the fuel tank nipple. It can be removed and cleaned with a can of carb cleaner or it can
be replaced.
See Figure 4.4.
NOTE: If cleaning a filter, back-flush it by spraying the carb cleaner through the barb end and out of the
screen. Also make sure the fuel tank is clean.
NOTE: To replace the fuel filter follow the steps described in Chapter 1: Introduction.
Inspect the fuel lines
• Are they cracked?
• Are they clogged?
• Are they brittle?
NOTE: If the answer to any of the above is yes, replace the fuel lines. When replacing fuel lines, low perme-
able fuel line must be used in order to meet EPA and CARB standards.
NOTE: The nipple has a sharp edge that will damage the inner lining of the fuel line. Replace the fuel line
every time it is removed from the carburetor fuel nipple.
• Drain the fuel tank before starting work to prevent spillage.
• Dispose of drained fuel in a safe and responsible manner.
