Bosch original 313GC5233MX Diesel Fuel Injection Unit Pump for Truck Diesel Engine, E7 Series Trucks, Replacement for OEM Fuel Injection Unit Pump original new injector

Engineered for the Mack E7 diesel platform, the BOSCH 313GC5233MX Electronic Unit Pump (EUP) is a high-precision, electronically controlled fuel injection component from the Bosch 755 Series. Built to OEM standard and supplied in export-standard packaging, it serves Mack E7-350, E7-400, E7-427, and E7-460 engines, including E-Tech and ASET variants, across highway trucks, vocational vehicles, construction equipment, generator sets, and industrial diesel applications.

Utilizing Bosch Electronic Unit Pump technology, the plunger is mechanically actuated by the engine camshaft while the ECU precisely controls the solenoid valve, enabling electronically adjusted injection timing and high-pressure fuel delivery. This operating sequence delivers accurate fuel metering and optimized atomization through the injector nozzle, resulting in maximized combustion efficiency, reduced fuel consumption, improved power output, lower emissions, better cold starting, and enhanced engine response under demanding heavy-duty operating conditions.

Manufactured with industrial-grade materials, the 313GC5233MX combines high-pressure injection capability, electronic control precision, superior durability, and extended operational lifespan with low maintenance cost. It cross-references 313GC5233M, 0414755014, 0414755015, 0986445011, 0986445012 and RX variants, plus PAI 8765X, Lucas LDFC0199, and Diesel Pro FIE20152, fitting Mack CH613, CHN613, CX613, CXN613, CV713, CT713, GU713, Granite, Vision, and Pinnacle trucks. For dependable service life, use high-quality diesel fuel, replace filters regularly, avoid contaminated fuel, and perform periodic injector diagnostics.
