Frequently Asked Questions - Injector Servicing

Q- What does a service involve?

A- When injectors come in for a service, they are inductance load tested, pressure tested, pre flow tested, ultrasonically cleaned whilst pulsing them with the machine, back-flushed to remove any debris and final flow tested. If they have metal bodies such as the Bosch EV1 / Weber / Lucas injectors, they will also be stripped of paint and rust, acid-etched and hot bake painted. After this has cured for 48 hours, new parts are installed, and the report of the findings is drafted up. As all injector services are slightly different, this will differ depending on the job.

A- Standard port injectors - £22.50 per injector, includes repainting if required, the parts kit is priced separately.

Q- How do I book a service?

A- Email mrinjectorukware@gmail.com, use the 'Contact Us' page or phone 07950 281293.

Q- Will I receive anything telling me the results of the service?

A- Yes, we record all before and after readings of the injectors' spray patterns, leak test results, load testing results, flow rates and percentage of flow rate increases. We'll also stipulate what we have done to the injectors and any recommendations we have.

Q- How do I know what injectors I have?

A- The numbers are stamped on the bodies of the injectors themselves; these can sometimes be seen with the injectors in situ, without having to remove them. If you can get your injector numbers or a few photos of them, this will make it easier to help you.

Q- Can you service just one or two injectors from my set?

A- No, the whole set would need balance checking to ensure they're within the manufacturer's recommended drift allowance and are balanced as a set; we need to ensure none are over- or under-fuelling.

Q- I'm not in the UK, can I still send in my injectors for service?

A - We no longer accept injectors from outside the UK. Please email us for more info.
