Your fuel injectors are crucial to the overall performance of your diesel engine, and they play a large role in your fuel economy as well.
We know that if your injectors start to fail, you want the issue taken care of right away and with the best parts possible.
Highway & Heavy Parts has you covered! We have a full line of fuel injectors from PurePower Technologies ready for your Navistar or Ford applications.
In the past, these injectors have only been available to the OEM, but now you can get them from HHP. This post takes you through the benefits of these great injectors, as well as how to decide if new injectors are what your diesel engine needs.

What Do Fuel Injectors Do In Your Diesel Engine?
In short, your fuel injectors are the primary fuel delivery system inside your diesel engine. They atomize the fuel as it enters the combustion chamber.
They mix the fuel with air before releasing it into the chamber, changing it into a high-pressure spray.
This is what helps you get the fuel economy and power you’re looking for.
What are Potential Fuel Injector Failures?
If you’ve noticed low power, excessive smoke or poor fuel economy, your fuel injector might be having problems.
When operating correctly, your injectors help your engine achieve peak performance and fuel economy.
But, if your injectors start failing, you’ll experience a decrease in efficiency.
Other symptoms to keep an eye out for include:
- Engine misfires
- Rough idle
- Excessive exhaust smoke
- Engine knocking
There are a wide variety of reasons why your injectors might fail, including:
- Secondary damage from previous failure
- Air or water in fuel system
- Age
- Wear
- Clogs
- Leaks from broken seals
- Cracks
- Internal component failure
- Other leaks
- Blown injector tip
- Improper injection timing
