Fuel Injection Pump Types
Mechanical Inline Injection Pumps
Mechanical inline pumps use individual pumping elements to deliver fuel to the engine cylinders.
They are commonly found on older and heavy-duty diesel engines.
Rotary / Distributor Pumps
Distributor-type pumps use a compact pump design to distribute fuel to multiple cylinders.
Common Rail High-Pressure Pumps
Common rail pumps generate high fuel pressure for a common rail system. Bosch describes common rail pumps as supplying precisely controlled fuel quantities while maintaining the required rail pressure.
Unit Pumps
A unit pump provides high-pressure fuel delivery for an individual cylinder.
Unit Injector Systems
The pump and injector are integrated into a single assembly. Bosch’s unit injector system combines a nozzle holder with an integrated high-pressure pump.
Signs of a Faulty Diesel Fuel Injection Pump
A failing fuel injection pump may cause:
- Hard starting
- Engine won’t start
- Loss of engine power
- Poor acceleration
- Excessive fuel consumption
- Black smoke
- White smoke
- Engine misfire
- Rough engine operation
- Uneven engine speed
- Low fuel pressure
- Incorrect injection timing
- Engine surging
- Poor performance under load
- Excessive exhaust smoke
- Fuel leakage
- Difficult cold starting
- Reduced machine productivity
Important: These symptoms do not automatically mean that the injection pump is faulty.
Fuel filters, injectors, fuel lines, lift pumps, wiring, sensors, ECU systems, fuel contamination and other engine problems can produce similar symptoms.
How to Identify the Correct Fuel Injection Pump
Before ordering a diesel injector pump, provide as much information as possible.
Recommended information:
1. Engine manufacturer
Example:
Caterpillar
2. Engine model
Example:
CAT 3306
3. Machine model
Example:
CAT 966 Loader
4. Engine serial number
The engine serial number is often essential for confirming the correct specification.
5. Existing pump part number
Send the number stamped or marked on the pump.
6. Pump manufacturer’s number
For example:
- Bosch number
- Zexel number
- Denso number
- Delphi number
- Stanadyne number
- OEM number
7. Photos
Send clear photographs of:
- Pump nameplate
- Pump identification number
- Pump mounting area
- Existing pump
- Engine data plate
Fuel Injector Pump Part Number Cross-Reference
Where possible, Nkokhi Group can assist with identifying equivalent or replacement fuel injection pumps using:
- OEM part numbers
- Bosch numbers
- Zexel numbers
- Denso numbers
- Delphi numbers
- Stanadyne numbers
- Pump model numbers
- Engine serial numbers
- Machine serial numbers
Do not order a fuel injection pump based only on the machine model.
The same machine model may have different engines, production years or fuel-system configurations.
Tips When Buying a Diesel Fuel Injection Pump
1. Confirm the Engine Serial Number
The engine serial number can be more important than the machine model when identifying the correct pump.
2. Compare the Existing Pump
Check:
- Mounting configuration
- Drive arrangement
- Number of cylinders
- Delivery configuration
- Pump timing
- Electrical connections
- Fuel connections
- Identification plate
3. Check the Part Number
Always provide the complete number when requesting a quotation.
4. Be Careful With Used Pumps
A used injection pump may have unknown operating hours or internal wear.
Ask whether the pump has been inspected, tested or reconditioned.
5. Consider a Reconditioned Pump
A professionally remanufactured or reconditioned pump may provide an alternative to purchasing a completely new assembly, depending on the application.
6. Check Fuel Contamination
Water, dirt and poor-quality diesel can damage precision fuel-system components.
7. Replace Fuel Filters
A blocked or contaminated fuel filter can contribute to fuel-system problems.
8. Do Not Replace the Pump Without Diagnosis
Before purchasing an expensive injection pump, confirm that the pump is actually the source of the problem.

Frequently Asked Questions
What is a fuel injector pump?
A fuel injector pump, commonly called a diesel fuel injection pump or injector pump, is a component that delivers diesel fuel to the engine’s injection system at the required pressure and timing.
What is the difference between an injector and an injector pump?
The injector delivers fuel into the engine combustion chamber, while the injection pump generates or controls the high-pressure fuel delivery required by the injection system.
