Diesel Pump and Injector Testing 

We are proud to provide technical knowledge and service to the majority of main dealerships and garages across the north of Scotland.

We are able to repair all types of diesel engine vehicles using the very latest technology, from vintage tractors to modern common rail systems. We also repair diesel pumps, diesel injectors, diesel lift pumps and diesel rotary inline pumps from all the major manufacturers such as Bosch, Lucas, CAV, Delphi, Simms, Siemens, Stanadyne and Zexel.

We have recently taken delivery of a new common rail injector diesel test machine New diesel test machinedesigned to test Bosch (automotive and commercial), Denso, Delphi and Siemens injectors.  This allows us to offer our customers a 'drive in' service where we can take delivery of your vehicle, remove, test and report on your injectors and significantly reduce your vehicle down-time.  

Precision can also supply new or remanufactured injectors and fuel pumps at very competitive prices. 

If you are looking for a specific diesel pump then we do have some older models kept in the workshop. Click here to open our latest stock details.
