A fuel filter, also known as a fuel strainer, is a filter lining located in most internal combustion engines and t is used to filter out dirt and rust particles from the fuel. Our fuel strainers prevent clogging and the loss of pump prime, distribution of gas, by using a suction strainer. Also many of our fuel filters can block water infiltration because they contain a water-absorbing polymer or water strainer which absorbs and traps water as it passes through the filter element.
