Diesel Engine Fuel System Specification Example for Camper Conversions: Fixed Type

This is a worked specification for diesel engine fuel system in a fixed type programme. It is the document we would send a buyer who asks what exactly they are getting: the material, the dimensions that are actually controlled, the finish, and the checks that happen before anything is packed.

The fixed type version exists because the duty cycle on camper conversions is not the same as on a showroom vehicle. Where the two are specified identically, something fails later — usually a specification nobody had written down.

  2. Fix the base material in writing — Chromed Steel, in this example.
  3. List the dimensions that are actually controlled and the tolerance on each.
  4. Name the finish and what it has to survive.
  5. State the inspection level and who pays when a lot fails.

Where this example applies

Programmes that run fixed type most often specify this build for camper conversions. Related applications include boat trailers, aftermarket retail, rental motorcycles, utility trailers, off-road bikes.

Checks before packing

  • Dimensional report against the approved drawing.
  • AQL 4.0 sampling on the finished lot.
  • Finish inspection under agreed lighting.
  • Carton drop test on the first lot of a new packing specification.

Questions buyers ask

What testing is included?

Standard lots ship with dimensional and hardness reports. ISO/TS 16949 documentation is issued with the shipment when your market requires it.

Do you handle mixed containers?

Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.

How long does sampling take?

Samples leave the factory in 14 working days, and each revision round adds about 3 days once you have seen the first piece.

What is the minimum order quantity?

The standard MOQ is 500 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
