Fuel Injector Overhaul Kits

We stock Master Injector UK's full 200+ catalogued overhaul and seal kits to suit standard port, direct high pressure (GDI), side feed and Bosch / Siemens Piezo injectors.

They have also designed overhaul kits for your historic hose to rail injectors, which include replacement ethanol-resistant hose lengths.

Replacing the hoses on your classic vehicle is essential now, considering the ethanol content in forecourt fuels today. Our hose is used in the aerospace and aviation industry, it is 100% ethanol proof. These kits will help to futureproof your classic vehicle.

These kits can be used to replace the seals and parts on your injectors when you know that they are working as they should be. These parts won't fix running issues.

If you're experiencing misfiring, leaking, poor acceleration or other issues, you would be best booking in a service with Mr Injector UK - 07950 281293.

I don't think I have ever described any company as a 'Class Act' but this guy deserves this accolade for sure. Communication from before sending in the injections through to the detailed report and despatch details was excellent and honest. Thanks James & Sian.

Great communication, helpful when encountering issues and process is both easy and efficient. Wish I had used the service before I found out the painful way my injectors were duff! Back on track now, thanks!
