Cross reference: 2102391, 2102391PEX, 2102391PR

Why Replacement is Important:

Over time, unit pumps can lose calibration or develop internal wear that affects pressure consistency and timing. Replacing a worn pump prevents engine misfires, reduces emissions, and avoids performance instability under load.

Impact on Vehicle Performance:

This unit pump directly influences fuel atomization and injection timing. A properly functioning unit restores smooth acceleration, reduces fuel consumption, and maintains torque levels critical for heavy-duty operation.
