Case Study: Fuel Pressure Regulator Supply for a supermarket chain in Central America

Fuel Pressure Regulator for A supermarket chain in Central America

A supermarket chain came to us with a fuel pressure regulator programme for Central America. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • A fitment that looked right on paper and failed on the bench
  • Lead time that slipped twice before bulk started
  • Reorders that did not match the approved sample

What was specified

PartFuel Pressure Regulator
ClientA supermarket chain
MarketCentral America
Volume2,000 pieces across 3 specifications
Base materialPolypropylene
Sampling rounds2
Delivery window6 weeks from PO to ex-factory
ComplianceTUV

How it was resolved

  1. The specification was rebuilt around Polypropylene and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Fuel Pressure Regulator production run

Result

  • 2,000 pieces delivered inside the 6-week window.
  • Unit cost held within 4.5% of the original quotation.
  • Inspection-related rejection stayed under 0.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
