Injector bodies can look nearly identical while calibration, connector and nozzle details differ. A useful inquiry starts with the complete stamped reference and enough context to check the application.
Scope and decision boundary
This guide applies to B2B pre-quotation identification of diesel fuel injectors. It does not confirm calibration, installation procedure or final interchangeability without the complete engine application and supplier documentation.
Capture the full stamped reference
Clean the body without grinding or polishing the marked surface. Photograph every line of letters and numbers, including suffixes. A partial number can point to a different calibration family.
Add machine and engine context
Send the machine make and model, engine model, serial plate and the quantity required. If the old injector is available, include overall, connector, nozzle and fuel inlet views.
What the sourcing review checks
The review compares the OE reference, physical interface and stated application. Supplier availability, minimum order quantity, packing and logistics are confirmed separately in the quotation.
Buyer checklist
- Complete OE or replacement number
- Engine and machine model
- Connector and nozzle photos
- Quantity and destination country
What the evidence can and cannot confirm
The review uses buyer-supplied stamped references, nameplate images, connector and nozzle views, plus current supplier or manufacturer reference records when available. A visual match alone is not treated as final fitment evidence.
Buyer questions
Can a photo replace the OE number?
A clear photo helps, but a complete stamped number and engine model reduce mismatch risk.
Why are suffixes important?
Suffixes can distinguish connector, nozzle or calibration variants within the same injector family.
Is price shown online?
No. Compatibility, quantity, packing and destination are reviewed before a supplier quote is prepared.
