Fuel Tank

11.6.1 Pickup Body

The diaphragm pump draws fuel out
of the tank and into the carburetor
via the fuel hose. Any impurities
mixed with the fuel are retained by
the pickup body (filter). The fine
pores of the filter eventually become
clogged with minute particles of dirt.
This restricts the passage of fuel
and results in fuel starvation.
In the event of trouble with the fuel
supply system, always check the
fuel tank and the pickup body first.
Clean the fuel tank if necessary.
