Patent ID: 8651068

Claim:
A device for separating water and contaminants from fuel that is being supplied from an upstream fuel reservoir to a downstream internal combustion engine, the device comprising: a housing that couples with the fuel reservoir, the housing having an inlet receiving fuel, water and contaminants, and an outlet discharging the fuel; a gravity separator disposed in the housing between the inlet and the outlet, the gravity separator separating the water from the fuel; wherein the housing comprises a water cavity holding the water separated from the fuel and a fuel cavity supplying the fuel to the outlet; a filter disposed in the housing between the inlet and the outlet, the filter filtering the contaminants from the fuel; a primer priming fuel for consumption by the internal combustion engine, the primer comprising a cap that is biased into an extended position, wherein pressing the cap out of the extended position primes fuel from the reservoir for consumption by the internal combustion engine; and an outlet valve that is biased into a closed position on the outlet and an inlet valve that is biased into a closed position on the inlet, wherein pressing the cap out of the extended position opens the outlet valve and supplies fuel, to the internal combustion engine and wherein releasing the cap closes the outlet valve and opens the inlet valve so as to prime fuel from the reservoir into the housing.
