Why It’s Time to Change Mack Engine’s Fuel Injectors
Injectors push diesel into combustion chambers. When they wear out, your truck shows it right away. Look for these telltale signs:
-
Choppy Idle or Hard Starts
Does your engine shake when idling or require multiple crank attempts? Old injectors often struggle to spray fuel evenly, causing rough running. -
Thick Black Smoke
A healthy Mack should run clean. If dark exhaust clouds appear when you accelerate or sit idle, your injectors may be leaking or clogging. -
Rising Fuel Bills
Notice your diesel budget climbing? Worn injectors can send too much or too little fuel into the cylinders, cutting efficiency. -
Weak Acceleration Under Load
If you feel hesitation when towing heavy freight or climbing hills, uneven fuel delivery could be to blame. -
High Mileage or Severe Use
Engines like the Mack ENDT 673C that see long hours of work can push injectors past 200,000 miles of duty. After that point, the injector internals wear down.
Putting off replacement risks damage to the high-pressure pump, turbocharger bearings, and exhaust-emission gear. Swap your injectors now and stop problems before they start.
Choose from Injector Choices that Fit Every Budget
Every repair budget is different. That’s why we offer three injector grades for Mack engines:
New Fuel Injectors
- Factory-Grade Performance: Built by leading OEM suppliers to match Mack’s original standards.
- Seamless Fit: Our new units fit EM6, E6, and E9 models without modification.
Rebuilt (Remanufactured) Injectors
- Complete Refurbish: We get rebuilt units from over 500 remanufacturers globally. Each rebuilt injector comes with replaced seals, valves, and restored tolerances.
- Better Value: Near-new performance at a fraction of the cost of brand-new parts.
Inspected Used Injectors
- Pre-Owned Savings: We inspect nozzle tips, pintles, and connectors to ensure reliability.
- Ideal for Older Trucks: Perfect when engines like the Mack E7 or ENDT 673 have outlived their original injectors.
No matter which tier you choose, new, rebuilt, or used, you’ll find competitive pricing, fast shipping, and expert support.

Enter that part number or engine model into our website’s search bar. Results will show new, rebuilt, and inspected used options. -

Our Injector Inspection Process
Every injector must pass a strict quality check before shipping:
-
Visual Check
We examine each injector for cracks, corrosion, bent pintles, or damaged nozzles. Any unit with visible flaws is rejected. -

All rubber seals, O-rings, and electrical connectors are inspected for integrity. Proper seating ensures no leaks and solid connections.
This process applies to brand-new, rebuilt, and inspected used injectors alike to ensure consistent reliability.

Frequently Asked Questions
Are these genuine Mack injectors?
Our new injectors are manufactured by top OEM suppliers to match Mack’s specifications. Rebuilt injectors are remanufactured to the same tolerances. Used injectors are factory-original but inspected to confirm they still meet performance criteria.
How does a remanufactured injector differ from a used one?
Rebuilt injectors are completely disassembled, have all wear components replaced, and pass strict inspection tests before shipping. Used injectors keep the original parts and are thoroughly visually inspected. Rebuilt units offer close to OEM performance at a better cost.
How quickly can you ship MD13 or ENDT 673 injectors?
Orders placed by 3:30 PM EST for in-stock injectors ship the same business day. Most continental U.S. deliveries arrive within a week via ground carrier.
Can you help me confirm fitment for my specific Mack engine?
Yes. Provide your engine serial number or VIN, and our Mack specialists will verify the exact injector model you need. We leave nothing to guesswork.
