  • General

    Common Rail has had such an impact on the diesel fuel injection trade, consequently demand for old type pumps and injectors has dramatically fallen but thanks to a number of enthusiasts restoring old vehicles and engines there has been a resurgence in popularity. In line with, we stock some old type pumps and injectors but we also have a wealth of experience in sourcing old style units.

  • Test and Report on Injectors and Pumps

    Modern vehicles are well known for poor fault diagnosis. A vast amount of money and time can be used to try and diagnose errors. Test and reports help to eliminate any errors or faults with pumps and injectors as part of the diagnosis process.

    We aim for a twenty four hour turnaround in fault diagnosis once we have received the unit for test. We can test 95 % of the current market of pumps and injectors and a swift diagnosis will help you pinpoint the fault quicker improving service to your customer.
