1. A liner for a suction manifold adapted to provide fluid to a plurality of intake ports of a multi-unit reciprocating pump, said liner comprising:
(a) a compressible, resilient body carried within said suction manifold;
(b) said body having a lateral slot running through its upper portion defining, when said body is installed in said suction manifold, a generally U-shaped channel, said channel extending through said manifold and adapted to convey fluid from an inlet of said suction manifold to said intake ports of said pump units; and
(c) wherein the cross-sectional area of said channel diminishes along the direction of flow through said channel.
