Fuel Pump for QJMotor SRK 400: Standard Replacement
This fuel pump is built for the QJMotor SRK 400 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 standard replacement programme stable once it moves from first order to repeat order.
Most buyers come to us after something went wrong: warranty claims traced back to a single lot, 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 — Kevlar Composite 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 QJMotor SRK 400 mounting, not on a catalogue drawing.
- Finish — powder coating holds up where the machine sees salt, mud and daily washing.
- Packing — individual packing plus inner cartons sized for the workshop bench.

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.

Ordering
- Confirm the model year and frame number before ordering.

Questions buyers ask
How long does sampling take?
Samples leave the factory in 14 working days, and each revision round adds about 5 days once you have seen the first piece.
Do you handle mixed containers?
Yes. Most programmes consolidate several part numbers into one container to keep freight sensible at 1000 pieces per line.
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.
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.
