Operation
Fuel Cap Service
The E engine uses a plastic fuel tank with a non-
replaceable 75 micron in-tank filter screen. The filter is
welded in the bottom of the tank over a sediment
reservoir. The tank is mounted above the level of the
carburetor and uses gravity to supply fuel through a
1. The fuel cap may not be disassembled; however,
the vent opening on the cap and inner sealing disc
should be kept free of debris.
2. The venting ability of the cap may be tested by
filling the cap with water and observing the flow of
water out of the vent opening in the top of the cap.
If water does not drain, the vent opening may be
plugged or restricted.
.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 opposite the fuel
outlet, helping to prevent damage to the filter screen by
funnels and gasoline filler spouts that may be inserted
into the fuel tank during refueling. The placement of
the cap also prevents interference with the starting
rope in Zone Start mower applications.
3. If the fuel cap will not vent properly, replace the
entire cap assembly.
4. Should you encounter a situation where fuel leaks
around the threads of the fuel cap (not out the
vent), inspect the top of the neck of the fuel tank
and the area in the cap where the fuel tank neck
contacts the cap. This is the sealing area, not the
threads. (See Figure 45.)
The fuel cap is a four piece design (see Figure 44) 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 or splash against the bottom of
the cap, 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. (If an
individual part of the cap fails, the entire assembly
must be replaced.)

Cleaning
1.
Remove the fuel tank. Take it to an appropriate
area, and wash the tank in clean solvent intended
for cleaning engine parts.

2.
Backwash the filter screen by directing cleaning
solvent, under moderate pressure, through the
sediment reservoir and screen, opposite the
direction of fuel flow.

4.
Wash the tank again with clean solvent.
Clean or replace the fuel hose.
