Before carrying out the repair please note:

The CP1 fuel pump operates at extremely high pressures, more than high enough to cause serious injury or death. Follow your vehicle manufacturers guidance on depressurize the fuel pump before commencing repair. The repair needs to be carried out in an ultra clean environment; any contaminates greater than 2 micron (0.0002mm) that enter the pump or pipework can cause irreparable damage to the injector system. Customers have noted success in the past carrying out the repair submersed in pure and filtered diesel using latex gloves to handle the components, with the pump being thoroughly flushed through with clean diesel before being refitted to the vehicle. It is the customer’s responsibility to ensure a sufficiently clean environment for this repair.
