Remanufactured Bosch Electronic Unit Pump for Mack E7 E-Tech and ASET Engines

This remanufactured Bosch Electronic Unit Pump (EUP) is designed for compatible Mack E7 E-Tech and ASET 12.0L diesel engines. The pump pressurizes and meters fuel for delivery to an individual cylinder at the correct time, supporting reliable starting, efficient combustion, stable engine operation, and consistent power delivery.

Each electronic unit pump is remanufactured using OE tools and processes. Critical wear components are replaced, applicable engineering updates are incorporated, and the completed pump undergoes end-of-line testing using OE test equipment and specifications.

Common Signs of a Failing Electronic Unit Pump

• Hard starting or extended cranking
• Rough idle or cylinder imbalance
• Engine misfire
• Reduced power under load
• Excessive exhaust smoke
• Increased fuel consumption
• Unstable fuel delivery
• Engine or fuel-system fault codes

These symptoms do not automatically confirm pump failure. Similar problems may be caused by injectors, wiring, engine position sensors, low fuel supply, contamination, compression loss, or electronic control issues. Complete the appropriate diagnostic tests before replacing the pump.

Installation Recommendations

Installation should be performed by a qualified heavy-duty diesel technician following the current Mack service procedures for the specific engine serial number. Keep all fuel-system openings clean and protected during installation.

Before installing the replacement pump, inspect the fuel supply, injector, electrical connection, pump drive components, mounting area, seals, and related hardware. Identify and correct contamination, restricted fuel flow, wiring faults, or another underlying condition that may have contributed to the original failure.
