Tired of your troublesome CP4? Let's fix it! This CP3 adapter kit fits the CBEA/CJAA family of TDI's using a Bosch 0445010042 CP3 pump.
All parts are CNC machined in house. The kit includes the pump adapter plate, pulley hub, high pressure fuel line threaded adapter, banjo fuel fittings, and all necessary nuts and bolts for install.
The oem high pressure fuel line requires minor re-bending to work with this kit. A good quality 1/4" or 6mm tube bender is suggested.
It is available as a kit only or with a remanufactured pump with a 1 year warranty.
Until we have a free moment to make our own instructions, here is an archived copy of instructions written by 2micron from TDIClub. Please only torque the pump mounting nuts to 10-12lb-ft with anti seize on the threads.
