Fuel Pump for BYD F3: High Density Foam
This fuel pump for the BYD F3 is specified around high density foam, 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 a fitment that looked right on paper and failed on the bench, or a fitment that looked right on paper and failed on the bench. 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.

Questions buyers ask
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 500 pieces per line.
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 is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
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.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
