An injection pump for supplying fuel to an internal combustion engine includes a plunger coupled to a cam follower which can be moved in one direction to effect fuel delivery by a multi lobed cam. The plunger is returned following fuel delivery by a return mechanism including two levers one of which carries a roller engaging the cam and the other of which engages the plunger. An adjustment shoe is carried by the one lever and is engaged by the other lever to enable adjustment of the backlash in the mechanism.
