OPERATION
Fuel Tank
The Toro V Engine uses a 1.3 quart plastic fuel tank
with a non replaceable 75 micron, intank, filter
screen. The filter is welded in the bottom of the tank
over the outlet fitting. The tank is mounted above the
level of the carburetor and uses gravity to supply
fuel through a .25" I.D. (6.35 mm) rubber hose to the
carburetor. The fuel hose is friction fitted to the tank
outlet at one end and to the carburetor at the other
end.
The fuel tank is vented through an opening in the
fuel cap. The fuel opening on the tank is 1.75" (45
mm) in diameter and is opposite the fuel outlet. This
helps prevent damage to the filter screen by funnels
and gasoline filler spouts that may be inserted into
the fuel tank during refilling. The placement of the
cap also prevents interference with the starting rope
in zone start applications.
Fuel Cap
The fuel cap is a four piece design with an inner
sealing disc that is vented to a baffle assembly in
the body of the cap. The baffle assembly allows
expansion in the tank without the loss of fuel.
Atmospheric pressure is allowed into the tank from
an opening in the cap to allow gravity to feed fuel to
the carburetor. NOTE: If an individual part of the
cap fails, the entire assembly must be replaced.
