Diesel fuel system

Diesel pump and injector RFQ checklist

The core fields B2B buyers should send for diesel pump and injector compatibility, quantity and logistics review.

Direct answer

Fuel-system inquiries need more than a generic component name. The pump or injector reference, engine application and connection details establish the review route.

Scope and decision boundary

This checklist supports pre-quotation sourcing of diesel injection pumps, injectors and related repair components. Calibration, coding and on-engine service work are outside the website review.

Record every identification mark

Send readable photos of pump plates, injector stamps and any barcode or calibration label. Type the number in the message as well as attaching a photo.

Describe the application

Provide engine make, model, displacement or cylinder count when known, plus the machine type. Explain whether the request is replacement stock, a repair batch or a distributor order.

Separate compatibility from commercial terms

First confirm the reference and interface. MOQ, lead time, packing and freight can then be quoted against the requested quantity and destination.

Buyer checklist

  • Pump or injector reference
  • Engine and equipment application
  • Connection and mounting photos
  • Quantity, destination and urgency

What the evidence can and cannot confirm

The review relies on complete plate or stamped references, application details and connection photos. Supply scope, calibration status and included components must be stated in the supplier-confirmed quotation.

Buyer questions

Why type the number if a photo is attached?

Typed text makes the reference searchable while the photo allows the team to verify characters and suffixes.

Can used samples be reviewed?

Yes. Clear old-part photos and measurements can support the reference check.

Does the catalog guarantee fitment?

No. Catalog entries start the inquiry; fitment is reviewed against the buyer's supplied evidence.
