Industrial Injection XP500C XP 500 Series CP3 Fuel Pump for 6.7L Cummins

The Industrial Injection XP500C is the Cummins 6.7L version of Industrial Injection's flagship XP 500 Series CP3 high-pressure fuel pump — a race-proven, competition-grade injection pump engineered to push the limits of single-pump fuel delivery.

When the XP CP3 line first launched in 2015, it redefined what was possible in a single-pump common rail system. The XP 500 builds on that legacy with next-generation internals, delivering over 500 Liters Per Hour (LPH) of fuel flow — setting a new benchmark for CP3 pump output.

Key Features:

• 11.2mm Crankshaft — Oversized for dramatically increased pump stroke and fuel volume
• 9mm Plungers — Significantly larger than the stock 7.5mm plungers for superior flow
• DLC-Coated Internals — Diamond-Like Carbon (DLC) coating on all plungers and tappets for reduced friction, improved durability, and resistance to sticking
• Advanced High-Flow Gear Pump — Engineered to move maximum fuel volume efficiently at the high-pressure stage
• 500+ LPH Flow Rate — Exceptional output for extreme single-pump common rail applications

Important Notes:

• Requires a minimum lift pump capacity of 290 GPH
• This pump is intended for competition/racing use only. Photo proof of a race vehicle is required prior to shipment

The Industrial Injection XP500C CP3 pump is the top choice for diesel competitors and high-horsepower Cummins builds demanding maximum fuel system performance from a single CP3 application.
