Incorrect diagnosis of fuel injection systems is causing fleet operators substantial losses, and Reef Fuel Injection Services (RFI) is concerned that this not as apparent as it should be to industry.

Modern fuel injection systems require that fuel be delivered at a specific volume and pressure. Because the tolerances for fuel pressure variations are small it is extremely important that a logical series of diagnostic tests are performed to ensure an accurate diagnosis when problems occur.

Warren Hauser, operations manager at RFI, says that it is essential that diagnostics are conducted on professional test equipment capable of accurately examining the performance of fuel injectors and injection systems.

“It is only by doing the relevant test regime on equipment that is regularly calibrated that the customer can be assured of an accurate report,” Hauser says. “And it is this diagnostics data that is use to effect reliable repair work to injectors or complete fuel injection systems.”

RFI is an experienced accredited fuel injection system remanufacturer and through ongoing investment in equipment and personnel has established its position of one of few such companies that can service all five leading diesel fuel injection systems – Bosch, Caterpillar, Delphi, Denso and Stanadyne.

RFI operates state-of-the-art electronic diagnostic equipment which allows its technicians to access fuel systems on vehicle to check and diagnose. Hauser says that it is not only access to the latest technology that provides the quality service, but also to skilled technicians that have extensive product knowledge. “This facilitates the accurate diagnosis of all fuel injection problems,” he says.

Commenting on the issue of incorrect diagnostics, Hauser says it is a worrying scenario and can be attributed largely to situations where a dealer is ill equipped and does not have skilled fuel injection system technicians, but still does the diagnostic work. “These injectors are then sent to a third party repairer, and we have had several instances where we had to assist customers who have found themselves in a predicament where the fuel injection system problem was misdiagnosed, resulting in wasted time and money,” Hauser says.

The most important advantage that RFI offers is it is a single source remanufacturer where the diagnostics and the remanufacture are done in the same facility.

“Most significant to the customer is the access to rapid information, the responsiveness shown through ongoing communication and interaction with the fleet owner. This not only minimises the vehicle downtime, but through accurate diagnostics ensures that the correct repair work is done, Hauser concludes.
