Fuel Pressure Regulator for BYD F3: Polypropylene
This fuel pressure regulator for the BYD F3 is specified around polypropylene, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is inconsistent hardness between lots, or a specification nobody had written down. Both are specification problems, and both are preventable.

Fitment notes
Keep the old part until the new one is on the bench. Comparing them side by side settles questions a photograph never will.
Where it is used
The specification above is the one most often ordered for wet weather riding. Related applications include off-road trails, coastal delivery, farm use, airport ground fleets, heavy load hauling.
Quality and packing
- In-line inspection with AQL 1.5 sampling on every lot.
- Dimensional report issued against the approved drawing.
- Carton marking and barcode to your specification.
- Golden sample retained at the factory as the reorder reference.
Questions buyers ask
What testing is included?
Standard lots ship with dimensional and hardness reports. SAE J431 documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the SAE J431-compliant build instead of a fresh interpretation.
Can you match an existing sample?
Send a sample and we will reverse-engineer the specification, then produce a counter sample for approval before any bulk starts.
How long does sampling take?
Samples leave the factory in 10 working days, and each revision round adds about 5 days once you have seen the first piece.
Tell us the model, the fitment and the quantity and we will hold a production slot for you.
