FAQs

1. What is an injector pump and what does it do?

The injector pump controls how much fuel is delivered to your TD42 engine and when. It’s a necessary component for fuel efficiency, power delivery and overall engine performance.

2. Why upgrade to a high-performance injector pump?

Upgrading your injector pump from a standard injector pump to one or our 11mm or 12mm boost compensated performance injector pumps allows increased tunability from a non boost compensated injector pump. It allows for adjustment and precise fuel delivery to ensure the vehicle runs the very best for your application.

While ordering the correct horsepower for your needs ensures the injector pump is designed to perform as needed right out of the box, a dyno tune by someone experienced in tuning mechanical diesel engines will ensure the very best possible result for you. If you're unsure what is required to meet your goals now and into the future, or which GQ or GU TD42 injector pump best suits your build, get in touch with our team today!

3. Will this injector pump fit my Patrol?

Our injector pumps are designed for Nissan Patrol TD42 engines, including GQ TD42 and GU motors. If you’re unsure, our team can confirm compatibility based on your model and setup.

4. Is this pump suitable for turbo setups?

Absolutely. These Nissan TD42 injector pumps are precision-built for use with turbocharged TD42 engines and support common boost upgrades like intercoolers and exhaust systems.

5. Can I install the injector pump myself?

If you’re a confident DIYer or experienced with diesel engines, self-installation of a GQ or GU TD42 injector pump is possible. However, we recommend professional installation to make sure correct timing, optimal performance and preserve warranty coverage.

6. Do your injector pumps come with a warranty?

Yes, each pump comes with a warranty covering manufacturing defects. It’s part of our commitment to quality and customer peace of mind.

7. Can I speak to someone before ordering?
