Inline Fuel Injection Pump for Weichai Diesel Engines

An inline diesel injection pump meters fuel and delivers it to the engine’s injectors through separate high-pressure lines. Each engine cylinder is supplied by its own pumping element. For a Weichai fuel injection pump replacement enquiry, start with the full pump identification and engine serial number, then confirm the assembly and setup for your application.

The image shows an inline-style pump with a row of delivery outlets and an external control linkage. It is a catalogue reference; exact part number, manufacturer, supplied components and engine compatibility must be confirmed for the quoted unit.

Which Fuel Pump Does Your Engine Need?

  • Inline injection pump: a conventional injection assembly with pumping elements arranged in a row and separate delivery lines to the injectors.
  • Common-rail high-pressure pump: supplies a shared high-pressure rail. It belongs to a different injection-system design and is not a direct substitute for an inline pump.
  • Feed or transfer pump: supplies the low-pressure side of the fuel system. Specify whether you need this component or the complete injection pump assembly.

Compare the system on your equipment before requesting a replacement. Bosch’s diesel system guide (PDF, pages 2 and 11) explains common-rail and inline injection designs.

How to Match a Weichai Fuel Injection Pump

Match the pump identification, engine configuration and installation details together. A similar housing or the same engine-family name is insufficient to confirm interchangeability. Record all letters and number suffixes from the plates, including any governor identification.

CheckEvidence to send
Pump IDReadable pump plate photo showing the complete number, model and suffixes.
EngineFull model, serial number, rated power and rated speed from the engine plate.
UseEquipment make/model and operating application; mention previous engine or pump replacements.
DriveMounting flange, drive connection and installed orientation, with dimensions or drawings where available.
ControlsGovernor markings, levers, stop mechanism and any electrical connector details.
Oil / fuel linesViews of the fuel connections, attached feed pump and any external lubrication connections.

Take one overall photograph and close-ups of both sides, the drive end and each identification plate. Where markings are unreadable, send the engine details and any parts-list reference, and identify the missing information.

What to Confirm in the Pump Quotation

Ask for a written specification identifying the offered part number, manufacturer, condition and intended engine configuration. Check whether the governor, feed pump, stop device, drive components and seals are included. Confirm price, availability, dispatch timing, shipping terms and warranty for that offer.

If a test or calibration report is offered, check that it identifies the actual pump and the test specification used. Dedicated equipment is used to test conventional inline pumps, as described in Bosch’s diesel test equipment guide (PDF). These references explain the technology; they do not certify this product or identify it as a Bosch unit.

Fuel Injection Pump FAQ

Can a pump with the same housing replace the original?

Housing similarity alone does not confirm a replacement. The full pump identification, controls, drive and engine configuration need to be checked together. Ask for the proposed cross-reference and fitment confirmation in writing.

What should a pump test report include?

Request pump identification, test date, test specification and measured results. The report should relate to the offered unit and the required configuration. Confirm whether it is included before ordering.

Does the complete pump include the governor and feed pump?

Confirm the contents of the specific offer. Request an itemized assembly list and photos, including the governor, feed pump and stop device where applicable. Reference photographs do not define the delivery contents.

Is installation timing or calibration required?

Ask the supplier which configuration the pump is supplied in and what setup remains. A qualified diesel technician should follow the engine-specific procedure for installation, timing and commissioning. Use the applicable service data for settings.

Parts Enquiry FAQ

What information should I include in a parts enquiry?

Include the part number, engine model or serial number, quantity required, and destination country. Clear photographs of the engine nameplate and the old part can help explain what you need.

Can I choose a replacement using only the engine series?

Use the engine series to browse the catalogue, then confirm the exact part number and engine details before ordering. A category listing alone does not establish that every listed part fits every engine in that series.

What if I cannot find the part number?

Include clear photographs of any markings on the old part and the engine nameplate with your enquiry. Describe the component you need and provide any available engine model or serial-number information.

Where can I browse parts by engine series?

Browse Weichai Deutz 226B parts, WD615 / WD618 parts, or WP10 / WP12 parts. You can also visit the full product catalogue.
