Welham Diesel Injection

Common rail diesel services

Common Rail was first commercialised in about 1997 and features a high pressure fuel pump feeding into a single fuel rail. The solenoid activated injectors are then attached to this rail with individual fuel pipes rather than being attached directly to the pump as in the older direct injection system.

In addition to the work we do on the vintage diesel side, we also offer the same services for common rail pumps and injectors all the way up to Euro6 standards. The tolerances for common rail are far tighter than direct injection, but we have the skills and equipment to test and recondition your components to the manufacturer’s original specifications.

What specialist services do we offer?

We can check and test just about any diesel fuel pumps or injectors using our state of the art testbenches. Full reconditioning service where applicable, or we can obtain new units if preferred. 

We can also make up low pressure direct injection fuel pipes using your old ones as a guide. Vehicle work is strictly by appointment only, ring us on 0116 276 6831 (option 2) to book in.
