Programs & factory references
Founded in 2015, we specialize in the manufacturing and validation of critical components for diesel fuel systems, such as common-rail injectors. We believe that robust process control—not a single sample—best represents true mass-production capability. That’s why we continuously invest in our quality system and validation capacity, building a closed-loop quality management framework that is traceable, measurable, and continuously improving across the full value chain—from incoming inspection and machining to assembly and final shipment. Our core team brings 50+ years of combined industry experience in fuel systems, enabling end-to-end collaboration from drawing review and process planning to validation and volume production delivery.
- Production consistency: documented quality routines, incoming review, in-process checks, and production release review.
- Validation support: application-focused review and sanitized quality summary for qualified business buyers.
- Change management: controlled internal review for product updates, order requirements, and packaging needs.
What we do
Dieselink is an independent manufacturer of diesel fuel system components, specializing in XPI injectors. We focus on repeatability: process control + measurement + test + traceability — not single-piece output.

- Remanufacturing programs that require stable performance and documentation.
- Aftermarket brands qualifying a consistent XPI source with traceable records.
- Buyers who need evidence (test + cleanliness + traceability), not only claims.
Why XPI is difficult in the service market
XPI is an ultra-high-pressure common-rail system used in selected Cummins and Scania applications. In service markets, fitment and Trim Code requirements vary by application, so public pages stay at compatibility level and detailed review is handled during RFQ.
Test results must be converted into a trim code. Using an incorrect code can lead to knocking, vibration, smoke, noise, and unstable operation.
- Application information and Trim Code requirements should be confirmed before quotation.
- Compatible-application support is reviewed against part number, engine/vehicle information, and buyer requirements.
- Public pages do not publish internal procedures, parameters, or record-access mechanisms.

How Dieselink Supports Compatible XPI Supply
Dieselink supports B2B supply of compatible XPI injectors through part-number review, application confirmation, Trim Code support, and order documentation. Internal production data, process methods, and record-access mechanisms are not published on public pages.
Confirm support scope against part number, application information, and buyer requirements.
Public pages show only buyer-facing quality-support summaries.
Trim Code guidance can be coordinated during RFQ for compatible XPI applications.
Quality and release documentation is reviewed internally to support consistent B2B supply.

Engineering & customization
Need a model not in the
catalog? We can build it.
Beyond standard models, we support customer-requested development where feasible — using a controlled workflow from inquiry to pilot run to release.
- Inquiry & feasibilityPart number, application, targets, volumes, documentation needs.
- Drawing / spec alignmentWork from customer requirements, samples, and controlled characteristics.
- Prototype buildProcess route + critical dimensions verified before assembly release.
- Validation & calibrationDimension, performance, cleanliness, and trim-code workflow verification.
- Pilot → productionControlled ramp with traceability, test report outputs, and feedback loop.
What makes this credible for XPI
The factory workflow is built around XPI realities: dispersion control, correct trim code generation, cleanliness discipline, and database traceability that supports both procurement and service.
