Critical Handling & Liability Warning
Important: Fuel injectors—especially vintage hose units—are highly delicate. We strongly advise using a competent professional for removal, part replacement, and installation.
Improper handling can cause damage to injectors (some of which are no longer manufactured), making replacement impossible. All self-installation is undertaken strictly at your own risk; Mr Injector UK accepts no liability for handling or assembly damage.

Rebuild Kits vs. Diagnostic Servicing
Our overhaul kits are designed solely to replace consumable components on injectors that are already verified to be mechanically and electrically sound. Rebuild kits will not resolve underlying mechanical failures or engine running issues.
If your vehicle is experiencing misfires, leaks, or other performance symptoms, we recommend booking a comprehensive diagnostic and restoration service with our workshop.     
  • Workshop Services (UK Residents Only): To secure your service slot or request a quotation, please email your injector serial numbers (printed on the injectors themselves) to mrinjectorukware@gmail.com. Logistics & Postage: You are responsible for arranging the removal of the injectors from your vehicle and sending them securely to us. Once the service is complete, they will be posted back to you. 
  • Parts & Overhaul Kits (Worldwide Shipping): We ship our overhaul kits and components globally. Please note that import duties will not be added to historic kit orders sent to Canada, as they qualify for a customs exemption specifically for vintage and classic vehicles.
