LLY Duramax Injection Pump - Remanufactured Direct-Fit Diesel Replacement

Overview

This is an direct-fit injection pump for the LLY Duramax diesel. It is professionally remanufactured to OEM specification for a professional-grade repair that restores proper function and reliability to your truck.

What It Does & How It Helps

The injection pump generates the high pressure that feeds the injectors, and it is one of the hardest-working parts on a diesel. A failing pump causes hard starting, stalling, loss of power, a dead-pedal, and injection-system fault codes. A quality remanufactured pump restores correct fuel delivery and reliable starting.
