Important Information
Premature clogging of the filter is usually the first indication of problems with fuel
quality or cleanliness. However, fuel quality and cleanliness is rarely considered
when diagnosing a problem. Once a fuel filter problem occurs, customers assume
there is a machine related failure.
The fuel filter has done its job if the filter clogs.
The purpose of the filter is to stop
contaminants from being introduced into sensitive precision fuel system
components.
Fuel contamination is an everyday hazard. Many factors are involved, such as
biological contamination, water / condensation and debris ingress. To ensure fuel
system longevity, Toro fuel systems filter fuel to the highest standard recommended
by the engine manufacturer. Clogged filters can lead to the perception of lesser
performance when in reality the filter performs as designed.
Given all the factors discussed, our customers may be concerned and looking for a
way to extend filter life.
Correction:
The Filter Manufacturers Council has published Technical Service Bulletin 95-1R1
on the subject. This is a very good article. We recommend you read and refer to it
whenever the topic of fuel filter life is discussed.
Refer to Toro Service Bulletin General 03-05
. Although this bulletin refers to a
biodiesel conversion, some of the kits described in the bulletin have the added
advantage of larger filters and stronger fuel pumps. Installation of this kit can help
extend fuel filter service intervals over the original filtration system.
