9044Z071A / 33100-4X700 Delphi Fuel Injection Pump – 2.9L CRDi, High-Pressure Supply, Bench-Tested

Product type: Delphi high-pressure common rail (CRDi) fuel injection pump

Primary references: 9044Z071A; Hyundai/Kia OE 33100-4X700

Target users: Diesel repair shops, distributors, importers, fleet maintenance teams, and B2B spare-parts buyers

Product Overview

I work with diesel fuel-system parts every day, and for a high-pressure pump replacement I always start with the part number and engine application—not only the vehicle name. The 9044Z071A / 33100-4X700 pump is a Delphi CRDi high-pressure fuel-supply component associated with Hyundai and Kia 2.9L diesel applications. In the market, it is commonly listed for applications such as Hyundai Terracan and Kia Carnival/Grand Carnival, with 33100-4X700 used as the Hyundai/Kia OE reference.

For a buyer who is not a diesel specialist, the easiest way to understand this pump is: the pump builds and supplies the high-pressure fuel required by the common-rail system. If the pump cannot maintain the required fuel supply, the engine may become difficult to start, lose power, run unevenly, smoke, or stall. However, these symptoms do not prove that the pump itself is defective, so I recommend checking the complete fuel system before ordering.

Why I Recommend This Pump for B2B Replacement Work

1. Clear 2.9L CRDi application direction

The supplied product information identifies the pump with Hyundai and Kia 2.9L J-series diesel applications. That gives distributors and workshops a practical starting point for fitment screening.

2. Multiple reference numbers make identification easier

The main product reference is 9044Z071A, while 33100-4X700 is the key Hyundai/Kia OE number shown in the source data. I still recommend matching the exact number on the removed pump before purchase because related Delphi numbers can look very similar.

3. Bench testing is more useful than a simple visual inspection

For a high-pressure pump, appearance alone cannot tell us whether internal pressure generation and sealing performance are acceptable. Our stated quality process includes bench calibration/testing, pressure testing, and sealing inspection before delivery.

What I Verified About 9044Z071A / 33100-4X700

The original source material correctly positions this product as a common rail fuel injection pump, but some of its general FAQ text was written for injectors rather than pumps. I have removed those mismatched statements and rebuilt the page around the actual pump.

How I Check Fitment Before an Order

1. Check the number on the old pump. Start with 9044Z071A or 33100-4X700, then compare every character.
2. Confirm the engine application. For this product, the source data points to Hyundai/Kia 2.9L diesel applications.
3. Compare the pump body, mounting points, connectors, inlet/outlet arrangement, and drive interface with the existing unit.
4. Confirm the vehicle generation and emissions specification when applicable. The same vehicle name can use different fuel-system configurations.
5. Send me a clear photo of the nameplate or laser marking if the number is difficult to read. I prefer verifying a questionable order before shipment rather than correcting a wrong order afterward.

Common Symptoms and What They Really Mean

Hard starting or no-start

Possible causes include insufficient high-pressure fuel supply, air entering the low-pressure side, fuel restriction, injector problems, electrical faults, or incorrect timing/control. Do not replace the pump based on this symptom alone.

Unstable idle

Check fuel pressure stability, injector condition, fuel quality, air ingress, and control-system faults before condemning the pump.

Low power under load

A restricted fuel filter, low supply pressure, injector imbalance, or a high-pressure pump problem can all produce similar symptoms.

Excessive fuel consumption or black smoke

These symptoms can also come from injector faults, air-management problems, incorrect combustion conditions, or contaminated fuel. A complete diagnosis is more reliable than changing one component at a time.

Engine stalling

Check both the low-pressure fuel supply and high-pressure system. Electrical or sensor-related faults can create similar symptoms.

Factory Quality Control

As a manufacturer and wholesale supplier of diesel fuel-system spare parts, we focus on process control that a B2B buyer can actually understand. For this pump, the publishable quality statement is that units are bench tested/calibrated and checked for pressure and sealing before shipment. We also support bulk orders, customized packaging, and international delivery. I recommend keeping the test record and part-number traceability with each batch for easier after-sales handling.

Important Note About Specifications

I intentionally do not publish an exact rated pressure, pump weight, or production-year range as fixed specifications on this page. The uploaded source contains a 1200 bar / 3.5 kg / 1980–1995 row for 9044Z071A, but that row is paired with Peugeot 504/505 and Citroën CX/BX and is clearly inconsistent with the 9044Z071A / 33100-4X700 CRDi application described above. Publishing that row would create a misleading product page. For an export B2B website, I would rather leave an unverified field blank than publish a technically attractive but unreliable number.

B2B Ordering & Supply Support

For distributors, repair networks, and trading companies, I recommend sending the Delphi number, Hyundai/Kia OE number, engine model, vehicle model/year, and a photo of the existing pump. With those details, we can check the application before confirming the order. For mixed orders, please provide the complete part-number list so we can verify each item separately.

FAQ

Is 9044Z071A the same as 33100-4X700?

They are commonly cross-referenced in supplier and aftermarket data. For purchasing, I still recommend matching the number on the original pump and confirming the exact application before shipment.

Is this an injector?

No. It is a high-pressure fuel injection pump used in a common-rail diesel fuel system.

Which engines does it fit?

The supplied product information identifies Hyundai and Kia 2.9L diesel applications. Vehicle and emissions variants should be checked individually.

Can I order by vehicle model only?

I do not recommend it. The safest method is to provide the original pump number plus engine and vehicle information.

Do you bench test the pump?

The supplier quality statement specifies bench testing/calibration, pressure testing, and sealing inspection before delivery.

Do you support wholesale orders?

Yes. The source material states support for bulk wholesale, customized packaging, and global delivery.
