Fuel interface modules that can be used in automotive vehicle fuel systems can include a body that defines a fuel channel and a plurality of ports through which fluid communication with the fuel channel can be established. Some modules include a check valve, a shutoff valve, and a coalescing filter assembly that are each coupled with a separate port. The fuel modules can be quickly installed and can eliminate many of the installing materials typically associated with automotive vehicle fuel systems.
