Product Overview
This engine-mounted pump supplies low-pressure fuel to the injection system. Extended cranking, loss of prime or a machine that starves for fuel under load can be caused by a weak lift pump, but filters, suction leaks, tank venting and fuel lines should be checked before replacement.
Application data supports Case 1085B, 1150E, 1155E, 1840, 1896 and 2096, plus additional Case models that use the same Cummins fuel-system arrangement. Cross-references include several Case and Cummins numbers.
Common replacement versions use a two-bolt flange and manual priming lever. Compare bolt spacing, inlet/outlet thread locations and lever shape with the original pump.
