Restore Smooth Running Power to Your International/Navistar DT466
HHP’s remanufactured fuel injector for the International/Navistar DT466 (part number 5010983R91) is built to bring back the smooth idle, clean starts, and steady power your engine had when it was new. This G2.9 style electronically controlled injector is engineered as a direct replacement for the OEM AP66989 and 1848489C91 injectors used on 2005.5 to 2007 DT466 engines rated between 210 and 285 horsepower.
Is your DT466 idling rough, misfiring under acceleration, or burning through more fuel than it used to? Those are classic symptoms of a worn fuel injector. Once an injector starts to break down internally, fuel delivery becomes inconsistent, and the problems tend to snowball. A rough idle today can turn into a hard start, a fouled cylinder, or an expensive fuel system repair a few weeks down the road.
Not every remanufactured injector on the market is built to the same standard. Some competitors ship parts that look clean on the outside but were never tested to hold up over the long haul. HHP’s DT466 injector is different. Every unit is remanufactured in an ISO 9001:2015 certified facility, which means it goes through a consistent, documented rebuild process rather than a quick clean and repackage. That is how we back this injector with a full 24 Month Parts Warranty, well beyond what most aftermarket injectors offer.
HHP offers premium aftermarket fuel injectors for the DT466 at a much lower price than OEM replacement, helping you put money back into your fleet instead of into dealer markup. Each injector is built to strict tolerances for spray pattern and fuel delivery so your engine runs the way it was designed to. Our ASE certified technicians are on staff to answer any technical questions about your specific DT466 application, including whether your engine uses this electronically controlled G2.9 style injector or an earlier mechanical injection system.
This injector does require a core return. Choose to pay the refundable core charge for immediate shipment, or send your old core in first, which typically adds two to four weeks before your replacement ships. Paying the core charge keeps your truck or equipment moving without the extra wait.
With technical knowledge, quality remanufactured parts, fast shipping, and dependable customer service, HHP is the place to be for your DT466 fuel system needs.

FAQs About International/Navistar DT466 Fuel Injector, Remanufactured, 5010983R91
1. What engines is fuel injector 5010983R91 compatible with?
This remanufactured injector is designed for International/Navistar DT466 engines built from 2005.5 through 2007, rated between 210 and 285 horsepower. It is a direct replacement for the electronically controlled G2.9 style injector used on these engines.
2. Is this a mechanical or electronic injector?
This is an electronically controlled G2.9 style injector, not a mechanical injector. Earlier DT466 engines used mechanical injection pumps and DT466 mechanical injectors, while 2005.5 and later engines switched to this electronically actuated design. If you are working on an older mechanical DT466, confirm your engine’s fuel system type before ordering.
3. What OEM part numbers cross reference to 5010983R91?
This injector cross references to numbers including AP66989, AP66889, 1848489C91, 1848489C92, 1848489C93, 6926-PP, 6909-PP, DE089, and EX638489. If your old injector tag shows one of these numbers, this remanufactured unit is a match.
4. Is this a new or remanufactured injector?
This is a remanufactured injector, not new. It is rebuilt in an ISO 9001:2015 certified facility and tested for consistent performance, giving you reliable “”like new”” operation at a lower cost than a new OEM injector.
5. Do I need to send back my old injector as a core?
Yes, this injector requires a core return. You can pay a refundable core charge for immediate shipping, or send your old injector in first, which usually adds two to four weeks before your replacement ships.
6. What are common signs of a failing DT466 injector?
Watch for a rough or uneven idle, misfiring or hesitation under acceleration, increased fuel consumption, hard starting, or excessive smoke. Any of these symptoms can point to a worn or failing fuel injector.
7. What warranty comes with this remanufactured injector?
This injector is backed by a 24 Month Parts Warranty, which is longer than the coverage offered on many competing remanufactured injectors.
8. How long do I have to return my core for credit?
Cores must be returned within 45 days of delivery for full credit. Returns between 46 and 50 days receive 50 percent credit, and cores returned after 50 days do not qualify for credit.
9. Can HHP help confirm this injector fits my engine?
Yes. Our ASE certified technicians can help verify fitment based on your engine serial number or existing injector part number before you place your order, so you avoid the hassle of ordering the wrong part.
10. How fast will my order ship?
If you choose to pay the core charge, in stock orders placed by 2pm EST typically ship the same day, Monday through Friday. Sending your core in advance instead will add two to four weeks to your ship date.
