Scott and the team at Diesel Pumps are fuel injection and turbo charger specialists. They have specialised injector machines compatible with a wide range of injectors to ensure a fast & efficient turnaround to keep your vehicle operating.

When your injectors have reached the end of their lifetime, Diesel Pumps can supply new injectors direct from the manufacturer, and carry a range of rebuilt injectors.

Diesel Pumps also service petrol engine injectors; able to clean, and check flows & patterns.

Our New Age programmable machine allows us to clean, check flows and patterns of EFI injectors. This is often an overlooked, but crucial component, when servicing petrol engines. This is why it’s important to us that we keep up with details and technology. It ensures the service you’re receiving is the best on offer.

Whether it's Garrett, IHI, Mitsubishi, Holset, or BorgWarner, our experts ensure your turbo delivers optimal power. Scott and the team, known for their Kiwi ingenuity and efficient service, maximise your turbocharger's lifespan using our Gieser balancer. For replacements, we offer direct-from-manufacturer options and stock upgrade kits. Address oil dysfunction, the main cause of turbo failure, through regular servicing to minimize future repair costs. Whether it's servicing or power upgrades, Diesel Pumps has the solution for your turbo needs.

We also supply replacements direct from the manufacturer, and carry a range of upgrade kits on the shelf.

We all want more power and with manufactures often conservative in their settings it can be practical to up power and torque within safe limits. Be it a simple boost setting, fuel setting, timing setting or a full blown turbo and intercooler upgrade.

Diesel Pumps have many options available. We operate the Steinbauer Power Module for safe accurate upgrading of the latest electronically controlled diesel engines. Often this results in fuel economy gains in commercial truck and tractor fleet units.
