Originally published in the May edition of Australian Diesel Mechanic Magazine (ADMM), this article highlights Diesel Care's long-standing commitment to accurate diesel fuel injection diagnosis, testing and repair.
Produced in collaboration with PHINIA, the feature explores why proper diagnosis matters, the challenges of modern diesel systems, and how Diesel Care continues to support workshops, fleet operators and equipment owners across Australia with specialist testing equipment, technical expertise and precision fuel injection solutions.
Since 1947, Diesel Care Has Been Getting Diesel Fuel Injection Right
Anyone working in the diesel industry knows that some jobs simply aren't straightforward. Faults with no obvious cause. Components that appear serviceable but fail under proper testing. Machines that have already had parts replaced yet still don't perform as they should.
This is where Diesel Care stands apart.
Our work goes well beyond replacing parts. It requires accurate diagnosis, specialised testing equipment and decades of real-world experience to identify the true cause of a problem and repair it correctly the first time.
Since 1947, Diesel Care has supported the automotive, agricultural and industrial sectors with the supply, testing and servicing of diesel fuel injection components, along with fuel filtration, engine protection and performance solutions.
While diesel technology has changed dramatically over the decades, our focus has remained the same: precision, reliability and getting the job done right.
“Too often we see vehicles where parts have been replaced without actually fixing the problem. Proper testing and diagnosis saves time, money and frustration—for both the workshop and the customer.”
John Jamieson
Director / Tamworth Dealer Principal
Complex diesel problems don't need guesswork. They need proper diagnosis.
Precision Fuel Injection Solutions
Modern diesel engines operate with higher injection pressures, tighter tolerances and increasingly sophisticated electronics. That leaves very little room for error.
Diesel Care provides complete fuel injection solutions, including:
- Genuine and service exchange pumps and injectors
- OEM-standard testing and calibration
- A comprehensive range of diesel fuel injection components
- Fast turnaround to minimise downtime
Every component is tested and calibrated to OEM standards to deliver reliable performance across a wide range of applications—from 4WDs and light commercial vehicles through to agricultural machinery and heavy equipment.
To help maximise long-term reliability, Diesel Care also supplies fuel filter upgrades and catch can systems designed to protect engines from contaminated fuel and carbon build-up, two of the leading causes of failure in today's high-pressure diesel fuel systems.
No Guesswork. Just Proper Diagnosis.
When it comes to diesel faults, guessing is expensive.
Every repair begins with accurate diagnosis using advanced testing equipment to identify the root cause of the problem. Whether working on modern common rail systems or traditional mechanical fuel injection, the focus is always on delivering clear answers and dependable repair outcomes—not unnecessary parts replacement.
Our philosophy is simple:
Fix it properly. Fix it once.
Investing in the Future of Diesel Diagnostics
As diesel technology continues to evolve, so too must the equipment used to diagnose and repair it.
To meet this demand, Diesel Care has expanded its Tamworth branch with a dedicated testing and repair facility for Electronic Unit Injection (EUI) systems and Denso common rail fuel pumps.
At the centre of the facility is the Hartridge AVM2-PC, an advanced diagnostic platform capable of high-precision testing and calibration of diesel injectors and fuel pumps.
Its capabilities include:
- High-pressure simulation that replicates real operating conditions
- OEM-aligned test plans
- Automated testing for consistent, repeatable results
- Detailed performance reporting to identify incorrect flow rates, leakage and electronic faults
The system supports modern common rail systems, Electronic Unit Injectors (EUIs) and traditional mechanical fuel injection systems.
“Investing in the right equipment means we can remove the guesswork completely. It allows us to give customers clear answers and confidence that the job has been done properly.”
John Jamieson
Director / Tamworth Dealer Principal
The result is consistent, repeatable outcomes—whether servicing the latest high-pressure diesel systems or traditional mechanical injection equipment.
