Product Overview
Cummins 4937767 is a low-pressure transfer pump that supplies fuel to the engine's injection system. A weak transfer pump can cause extended cranking, low supply pressure, hesitation under load or stalling when fuel demand increases.
Cummins parts suppliers specifically cross 4937767 to the 4B 3.9, 6B 5.9 and ISB 6.7 families. That is a more useful application definition than generic 'B-series' wording because it identifies the engine families most consistently associated with this number.

Before You Order
Match 4937767 against the engine serial number or pump on the engine. Cummins B-series engines used multiple lift/transfer-pump designs over time, so displacement alone is not a fitment guarantee.
