A fuel pump for use in an internal combustion engine, the fuel pump comprising a pumping plunger for pressurising fuel within a pump chamber during a plunger pumping stroke, a rider member co-operable with a drive, and an interface member, for example a foot of the plunger or an intermediate tappet, for imparting drive from the rider member to the pumping plunger to perform the plunger pumping stroke. The interface member comprises an arcuate contact surface co-operable with the rider member. The inventive concept also extends to a pumping plunger for pressurising fuel within a pump chamber of a fuel pump, the pumping plunger comprising a foot having an arcuate contact surface for engaging a rider member of a fuel pump in use.
