A materials handling vehicle is provided comprising a power unit, a mast assembly and a fluid supply system. The mast assembly is coupled to the power unit. The mast assembly comprises a weldment, a movable element and a ram/cylinder assembly coupled to the movable element to effect movement of the element. The fluid supply system includes manifold apparatus and at least one fluid line coupled to the manifold apparatus and the ram/cylinder assembly. The manifold apparatus provides pressurized hydraulic fluid to the ram/cylinder assembly via the fluid line to raise the movable element. The manifold apparatus is mounted to the mast assembly.
