An apparatus includes a primer pump having a pneumatic power inlet, a fluid inlet coupled to receive a fluid from a fluid source and a fluid outlet to output the fluid in response to a pressure at the fluid outlet being less than a pressure at the pneumatic power inlet. The apparatus includes a liquid additive pump having a fluid inlet coupled to the fluid outlet of the primer pump to receive the fluid, wherein the primer pump is to apply a positive pressure at the fluid inlet of the liquid additive pump.
