Complete CP4 Fuel Pump Upgrade Kit for BMW N47S Engines

Complete CP4 Fuel Pump Upgrade Kit for BMW 123D N47S Engines with Piezo Injectors

Complete CP4 Fuel Pump Upgrade Kit, Including Fuel Rail, Sensor, Regulator and Lines for BMW N47S Engines

This Fuel Pump Upgrade can be fitted alongside the standard injectors or along with upgraded injectors

Rather than using a stock N47 CP4.1 Pump and fitting experimental parts, we decided to create a kit using the CP4.2 Pump as a base. It requires a bit more work to fit, and more parts, but is a much more robust setup, and makes any maintenance much easier as you are using off the shelf parts that are easily obtained in the future.

PLEASE NOTE, THERE MAY BE A FEW PARTS THAT NEED TO BE GROUND TO ALLOW FITMENT OF THE HIGH PRESSURE LINES, PLEASE SEE BELOW:

Remove and Grind Alternator Bracket
Remove and Grind Inlet Manifold - New Seals are included
EGR and Cooler need to be removed
Rail Bracket / Support and Decoupling element - Use original - Only 2 required instead of 3
Special Tool required for Pump Removal - See Link to this Item Below

THE FUEL RAIL SUPPLIED WITH THIS KIT COMES COMPLETE WITH USED FUEL PRESSURE REGULATOR & 2200 BAR FUEL PRESSURE SENSOR. WE HAVE BRAND NEW UPGRADED REGULATORS AND SENSORS LISTED FOR THE FUEL RAIL SUPPLIED IN THIS KIT, HOWEVER, IT IS NOT NECESSARY TO UPGRADE THESE PARTS.

You will have to upgrade the fuel rail pressure sensor if running more than 2150 BAR rail pressure, please find links below in this listing.

We also offer upgraded injectors for the N47S engines, these are not required when fitting this fuel pump upgrade, however, for the best results we recommend upgrading them. Please see link below in this listing.

This Kit is supplied with a different Fuel Rail (used) and Rail Pipes to the original as the Union Size is different for the Rail to Injector Lines. Everything to fit this is supplied.
Please be aware, the Fuel Rails supplied are Used but have been removed from Running Engines.
