Cummins Injection Pumps – VE, P7100, VP44 & CP3

CPP Diesel builds and supplies every major Cummins fuel injection pump: the rotary VE (’89–’93), the mechanical inline P7100 (’94–’98), the electronic rotary VP44 (’98.5–’02), and the common-rail CP3 (’03+). From stock replacement to competition-spec builds, we match your power goals with the right pump, injectors, and supporting hardware.

Quick Guide: Which Pump Do I Have?

1989–1993: VE rotary (1st-gen 12-valve)
1994–1998: P7100 inline “P-pump” (2nd-gen 12-valve)
1998.5–2002: VP44 electronic rotary (24-valve)
2003+: CP3 common rail (5.9L & 6.7L, model-year dependent)

What Makes Each Pump Different?

VE (1989–1993)

Lightweight rotary design with mechanical timing and excellent drivability. Available in stock, 12mm hot street, and 14mm race builds. Great throttle response and fuel economy; best with matched injectors and a properly sized turbo.

P7100 (1994–1998)

Six-plunger inline mechanical pump (“P-pump”) known for tunability and huge fueling headroom. Our 12mm Hot Street, 13mm High Performance, and optional 14–16mm competition builds support everything from daily/tow to full race with compounds and built fuel systems.

VP44 (1998.5–2002)

Electronically controlled rotary pump. Smooth delivery and good street manners with proper lift-pump support. We offer stock replacements and performance-oriented VP44 builds for hot street and mild competition.

CP3 (2003+)

High-pressure pump for common-rail systems. Offered in OEM stock form and 10mm/12mm/14mm stroker race builds (including Exergy). Pair with dual or triple CP3 kits for extreme horsepower while maintaining stable rail pressure.

Frequently Asked Questions

What size injection pump should I choose?

Match size to your goal: hot street/tow = VE or P7100 12mm; serious street/strip = P7100 13mm; dedicated race = P7100 14–16mm or CP3 12–14mm (often with dual/triple pumps).

Can I daily drive a 13mm P7100?

Yes—with correct injector/turbo pairing and tuning. Expect higher fuel demands and more frequent maintenance than stock.

Do I need dual or triple CP3s?

High-boost, high-HP builds usually benefit from multi-pump setups to stabilize rail pressure and protect components under load.

What supporting mods matter most?

At minimum: quality lift pump/fuel supply, injectors sized to the pump, and a turbo with adequate airflow. For larger pumps, add studs, valvetrain, transmission upgrades, and head sealing solutions.
