Built the Industrial Injection way
This is not a typical “reman” pump. Every unit is rebuilt using brand-new, genuine Bosch OEM internals (not reused, not refurbished). Internally and externally, components are replaced, tested, and calibrated to exceed Bosch OEM specifications, with the only original component being the pump housing.
Each pump includes a new Bosch Fuel Metering Valve (FCA) and is assembled, tested, and validated in-house using Bosch OEM-certified machines, test stands, and clean-room environments. The result is OE-level drivability with the durability you expect from Industrial Injection.

Whether your truck is a daily driver, hard-working tow rig, or long-haul workhorse, this CP3 supports stable rail pressure and smooth operation so your injectors and fuel system can do their job consistently.
