    Abstract: A fuel pump assembly comprises a plunger arranged to reciprocate within a plunger bore via a drive shaft, to perform a pumping cycle comprising a pumping stroke and a return stroke, the pumping stroke comprising movement of the plunger from a bottom dead centre (BDC) position to a top dead centre (TDC) position, and the return stroke comprising movement of the plunger from the TDC position to the BDC position. The fuel pump assembly comprises a spring assembly including a return spring that is cooperable, at a first end, with a first member coupled to the plunger and movable at a first speed dependent on the speed of rotation of the drive shaft and, at a second end, with a second member which is movable at a damped speed relative to the first speed.

    Abstract: A fuel tank isolation valve is provided having a main valve body including a fuel tank port and a canister port, a main bore, and an actuator selectively operable to allow or inhibit vented fuel vapors to move from the first port to the second port along a first path. The body can define an airflow bypass orifice that allows vapors to move from the first port, through the main bore, to the second port along a second path, while the actuator is in the closed mode inhibiting vapors from moving along the first path. This flow through the orifice can equalize pressure in a fuel tank and the canister during a purging operation on the canister. The valve can include a fitting that directly couples the valve to the canister without any intermediate hoses, in a cantilevered manner. A related method of use is provided.

    Abstract: An electrical connector for an electrical connection within a fuel system, the electrical connector comprising first and second electrical connector pins, and an overmould for the first and second electrical connector pins. Each of the first and second electrical connector pins includes an external portion which projects from the overmould, an internal portion to which the overmould is applied, and a chamfered portion located between the internal portion and the external portion. The internal portion of each of the first and second electrical connector pins includes a region having a first dimension adjacent to the chamfered region and at least two axially spaced projections which extend radially from the internal portion beyond the region having a first dimension, adjacent ones of the axially spaced projections being separated axially by a region of the internal portion having a reduced dimension compared to the region having a first dimension.
