The J-46375-A Injector Unit Pump Puller is the professional tool for safe, damage-free removal of unit fuel pumps (U-pumps) on Mercedes-Benz MBE 900 diesel engines—applies straight, controlled extraction force to prevent pump body damage, cylinder head bore scoring, or sealing surface distortion.

The Expensive Risks of Improper U-Pump Removal on MBE 900 Engines

• Pump body crack / fracture – $400–$1,200 new pump
• Cylinder head bore damage – $800–$3,000 head repair or replacement
• Sealing surface scoring – $500–$1,800 machining + new seals
• Fuel system contamination – $1,000–$4,000 additional injector/rail damage
• Downtime & labor overrun – Extra 4–12 hours at $150–$350/hr
• Rework & comebacks — $2,000–$6,000 total per bad removal
