Abstract: A vent shut-off assembly configured to manage venting on a fuel tank configured to deliver fuel to an internal combustion engine includes a first liquid vapor discriminator (LVD), a main housing, a poppet valve assembly, a pump and an actuator assembly. The first LVD is disposed in the fuel tank. The main housing selectively vents to a carbon canister. The poppet valve assembly has a poppet valve arranged in the main housing. The pump selectively pumps liquid fuel from the main housing. The actuator assembly is at least partially housed in the main housing and includes a cam assembly having a cam shaft that includes a first cam and a second cam. The first cam has a profile that one of opens and closes a poppet valve fluidly coupled to the first LVD. The second cam has a profile that actuates the pump.

Abstract: A pump assembly for a liquid trap of a vehicle fuel tank assembly includes a pump configured to couple to the liquid trap and selectively drain liquid therefrom, a sensor configured to monitor an inductive signature of the pump, and a controller programmed to operate the pump and monitor the inductive signature to determine if liquid is present in the liquid trap based on the monitored inductive signature.
