Claim 0:
1. A metering pump for dispensing a fuel additive, the metering pump comprising:
a pump body;
an inlet at which the fuel additive enters the metering pump and an outlet at which the fuel additive exits the metering pump, the inlet and the outlet being coupled to the pump body, the inlet and the outlet aligned in an axial arrangement;
a piston bore defined by and within the pump body, this piston bore oriented parallel to the axial arrangement;
a piston contained within the piston bore, the piston being configured to draw the fuel additive into the metering pump through the inlet and to dispense the fuel additive from the metering pump through the outlet;
an inflow valve coupled to the pump body and configured to permit the fuel additive to flow in a single direction away from the inlet and to prevent the fuel additive from flowing in an opposite direction back into the inlet; and
an outflow valve coupled to the pump body and configured to permit the fuel additive to flow in the single direction towards the outlet,
wherein the metering pump comprises a configuration in which the inlet, the outlet, the piston, the piston bore, the inflow valve, and the outflow valve are centrally positioned along a central plane of the pump body.
