11-16 GM 6.6 6.6L LML Duramax Diesel CP4 - CP3 Injector Pump Upgrade Conversion
CP4 to CP3 Conversion Kit
The Durmax factory CP4 fuel pump is prone to failure, whats worse they dont supply these trucks with a lift pump like other manufacturers do making the CP4 work even harder than it should. Convert your truck back to the more reliable CP3 fuel pump and while you are at it add a lift pump!
This conversion kit will also remove the factory fuel filter housing.
