Complete CP4 Fuel Pump Upgrade Kit for BMW N47 Engines

Complete CP4 Fuel Pump Upgrade Kit, Including Fuel Rail, Sensor, Regulator and Lines for BMW N47 Engines

This Fuel Pump Upgrade is to be used in conjunction with our N47 Solenoid Injector Upgrade (See Link to these Below in this Listing)

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.

This kit is currently fitted on a 118d with our GTB2260VK Turbo Kit and N47 / N47N Solenoid Injector Upgrade, plus a few other supporting mods, and the car is producing over 270 BHP

We will send a fitting guide via email once the order is placed. There are a few parts that need to be ground to allow fitment of the High Pressure Lines, 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 & Fuel Pressure Sensor. We have Brand New or 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 Pressure Sensor if running more than 2150 BAR Rail Pressure.
Please find links 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.
