Claim 0:
1. A priming system comprising:
a resilient chamber having a cylindrical portion comprising a resilient material that returns to a neutral shape after being expanded or compressed, an open first end and an open second end opposing the open first end;
an inlet port coupled to the open first end, the inlet port having a first inlet portion configured to receive an inlet tube, a second inlet portion coupled to a first end of the cylindrical portion of the resilient chamber, and an inlet passage extending through the first and second inlet portions, the inlet passage configured to receive a fluid from a fluid reservoir;
an outlet port coupled to the open second end, the outlet port having a first outlet portion configured to receive an outlet tube, a second outlet portion coupled to a second end of the cylindrical portion of the resilient chamber, and an outlet passage extending through the first and second outlet portions, the outlet passage configured to receive a fluid from the resilient chamber; and
a first check valve disposed in the second inlet portion of the inlet port, the first check valve configured to allow a fluid flow from the fluid reservoir toward the resilient chamber and to resist a fluid flow toward the fluid reservoir through the inlet passage,
wherein the fluid returns to the fluid reservoir through the outlet port and the outlet passage upon compression of the resilient material of the resilient chamber,
wherein the resilient material of the resilient chamber expands when the fluid is received from the fluid reservoir, through the first check valve, and into the resilient chamber.
