Bosch original 313GC5233MX Fuel Injection Unit Pump Diesel Injector for Mack Renault E7 Series Truck Diesel Engine 2003-2006 Replacement for OEM 0414755014 original new injector

Precision-engineered for the demanding operating conditions of the Mack E7 platform, the Bosch 313GC5233MX Electronic Unit Pump (EUP) delivers the exact metering accuracy and high-pressure delivery these engines require. Built to Bosch OEM specifications, this 755 Series unit pump is directly matched to the Mack E7-350, E7-400, E7-427, E7-460, and the E7 E-Tech and ASET variants, ensuring consistent fuel atomization across the full load and RPM range.

This EUP is fully cross-referenced to 0414755014, 0414755015, 0986445011, 0986445012, 0986445011RX, and 0986445012RX, simplifying procurement and inventory management for fleet operators and service centers. Engineered with industrial-grade materials, it offers electronic control precision, extended operational lifespan, superior durability, low maintenance cost, and high reliability under heavy-duty highway and vocational applications, including Mack CH613, CX613, CV713, GU713, Granite, and Vision trucks.

Correct installation maximizes performance: always clean fuel passages, replace damaged seals and O-rings, and apply OEM torque specifications. Perform post-installation leak testing, verify fuel pressure, and check ECU fault codes before return to service. Routine use of high-quality diesel fuel, regular filter replacement, and periodic injector diagnostics prevent hard starting, power loss, rough idle, white or black smoke, excessive fuel consumption, and solenoid failure—keeping Mack E7 engines running at peak efficiency.
