to be replaced removed for cleaning or repair the port pairs primarily located on the front and back surfaces 22 and 24 of the manifold 20 provide opposed surfaces to enable the manifold 20 to be mounted in different orientations to accommodate left hand and right hand pump and drive configurations for example the port pairs 66 and 68 for port p 3 and 70 and 72 for port p 4 are mounted on the front and rear surfaces 22 and 24 respectively likewise ports 122 and 124 gp 3 and gp 1 and ports 126 and 128 gp 4 and gp 2 are aligned on opposite front and rear surfaces 22 and 24 of the manifold 20 to accommodate a single fluid operative component connectable to the passage 120 on either of the front and rear surfaces through one of the aligned ports with any of the ports if a port on one of the passages in the manifold 20 is not connected to an external instrument or pipe it is blocked by a threaded cap or other closure member in summary there has been disclosed a manifold for a pump and driver apparatus which overcomes numerous deficiencies found in prior art pump and driver manifolds the present manifold allows a lube oil or seal system filter to be.
