Upgraded pumps draw more current than stock, so if you're on a weak or aged EKP2, it may overheat and shut down. We recommend upgrading to an EKP3.
European spec vehicles: The original top hat may need to be transferred over during installation.
Required tool: A fuel pump lock ring removal tool is required for installation. Our Fuel Pump Lock Ring Removal Tool for BMW E-Chassis, MINI, and Porsche is available separately - add it to your order from our store.
