CP4-CP3 Conversions

A CP3 conversion is often bought for peace of mind, not just more fuel. It replaces the factory CP4 setup with a pump design many diesel owners trust more, especially on trucks that tow, run tuning, or already have higher mileage.

The lineup covers CP3 pumps, CP4 to CP3 conversion kits, disaster prevention kits, fuel lines, rails, fittings, plus the smaller install pieces from Alliant Power, S&S Diesel Motorsport, and Fleece Performance Engineering. Check the kit details closely because some are emissions-compliant and some are not.
