Fuel Tank for Dayun 150: Two-Piece Construction
This fuel tank is built for the Dayun 150 and supplied to a written specification, so the part that comes off the line in the next order matches the one you approved. Fitment, base material and finish are fixed before sampling starts — that is what keeps the two-piece construction programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: packing that arrived crushed at the port, or a supplier who changed material without saying so. Both are avoidable when the specification is written down before bulk and the approved sample is kept as the reference.

What decides whether it lasts
- Material — Cast Iron is the base; treat any substitution as a new approval.
- Hardness and heat treatment — recorded per lot, not per batch of paperwork.
- Fitment tolerance — checked on the actual Dayun 150 mounting, not on a catalogue drawing.
- Finish — a sealed surface treatment holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.

Fitment notes
Confirm the fitment against the VIN or the frame number before ordering; two model years often share a name and not a part.
Where it is used
The two-piece construction build is the one most often ordered for urban courier work. Riders also fit it for adventure travel, construction sites, rural transport, coastal delivery.
Ordering
- Confirm the model year and frame number before ordering.
- Approve a sample made from the actual bulk material.
- Fix the packing and marking at quotation stage.
- Book inspection before the balance payment, not after it.
Questions buyers ask
What happens if a lot fails inspection?
The lot is re-inspected against the golden sample, and replacement pieces ship on the next available booking at our cost.
What is the minimum order quantity?
The standard MOQ is 2000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
What testing is included?
Standard lots ship with dimensional and hardness reports. IATF 16949 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 IATF 16949-compliant build instead of a fresh interpretation.
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
