Fuel Evaporation System Filter; Fuel & Evaporative System Line Routings - HUSTLER Super 104 General Service Manual

It is important to note that whenever an air filter element is
cleaned by any method, the person or company performing
the cleaning assumes responsibility for the integrity of the
filter from then on. The warranty for air filters expires upon
cleaning or servicing in any manner because the condition of
the filter after servicing is completely out of the filter
manufacturer's control. Therefore, on a dust ingested engine
failure, there will be no warranty consideration if the air filter
element has been cleaned or serviced in any manner.
A partially dirty air filter element works better than a new
element. Therefore, a dirty filter element is not bad for the
engine unless it is excessively restricting the air flow and
engine performance is affected. The media in the filter must
be porous to allow air to pass through it. When dirty air
passes through the filter, the dirt plugs some of the holes in
the media and actually acts as part of the filter media. When
the next round of dirt enters, the first dirt helps filter out even
smaller particles making the filter more efficient at stopping
dirt from entering the engine. This is referred to as barrier
filtration.
At some point the filter media becomes too clogged to
allow air to pass.
The mowing conditions will determine the frequency of air
filter element changing.
Air Restriction Indicator
These units have an air restriction indicator installed in the
air cleaner. Figure 5-9
Replace the element whenever the restriction indicator
reaches the change filter red line. Check the indicator daily
and replace element as needed or annually whichever occurs
first.

Reset the indicator by pushing in on the yellow button after
each element change. Figure 5-9

Fuel Evaporation System Filter

Some Hustler Super 104™ mowers have a fuel evaporation
®
system filter. This filter must be checked and replaced every
500 hours or annually whichever comes first. Figure 5-10
Fuel & Evaporative System Line Routings
There are two rubber hoses that are connected to the fuel
tanks. One is the fuel hose that is part of the fuel system. The
other is the vapor line that is part of the fuel evaporative
system.
The fuel hose is connected to the fuel tank as shown. It
connects the fuel tank to the fuel shutoff valve. Figure 5-11
The vapor line is connected to the fuel tank as shown. It
connects the fuel tank to the engine's vapor port. Figure 5-12
