Description: This fuel transfer pump is a high-quality replacement designed for Cummins diesel engines used in Case construction, industrial, agricultural, and generator applications.

The pump supplies fuel from the tank to the injection pump at the correct pressure to ensure proper starting, stable idle, and full engine power.

This style pump is commonly used on Cummins 4BT, 6BT, and 5.9 mechanical engines and is not interchangeable with later 6C / 8.3 lift pumps even though the housing may look similar.

Manufactured with precision-machined internal valves, durable diaphragm, and high-quality seals for long service life.
