Abstract
A fuel filter for preventing water and particulate contamination from passing therethrough, the filter having a rigid tubular fuel previous member having a first end and a second end, a flexible filter media surrounding the tubular member through which fuel freely passes from the exterior thereof into the tubular member but which resists the passage of particulate matter and water, a first end cap secured to the tubular member first end having an integral projectile portion extending within the tubular member direction toward the tubular member second end, the projectile portion being severable from the first end cap when differential fuel pressure thereacross reaches a preselected level, and, when severed, a passageway is formed through the first end cap, a second end cap secured to the tubular member second end having a passageway therethrough and having an annular seating surface, the projectile portion being configured to, when severed from the first end cap, engage and close against the annular surface of the second end cap to block further fuel flow through the filter.
