Fuel Filter
The deterioration of fuel is almost inevitable. Contaminants are introduced into the fuel system through mixing, transferring, and storage. These contaminants spread through the fuel system and quickly plug the fuel filter. A coating of slime will develop over the entire surface of the media.
Contaminants arrive in your fuel in two forms- precipitates and particulates. Precipitates are generally heavier than fuel, and tend to settle to the bottom of tanks.
