ABSTRACT:
A fuel control system is provided. Fuel is delivered into a main canister from a low-pressure pump, where it gathers in a reservoir or bottom area. The fuel in the reservoir is taken up by a small high-pressure pump inside the housing, which drives the fuel to the fuel injectors of an engine. The low-pressure pump has a flow rate exceeding that of the high-pressure pump. A vapor trap captures accumulating fuel vapor. Volumetric excess fuel and vapor are vented back to the fuel tank and atmospheric pressure. Vapor lock is reduced or avoided, and particulate and water filters are provided to avoid contamination.
