OE 31111-C1100 — Fuel pump core for Hyundai / Kia

Noise normally traces to worn internal surfaces, a loose mount, a dry bearing or contact with a neighbouring part. Isolate it by reproducing the sound at a fixed speed, then compare against the reference photo for 31111-C1100 to confirm the right replacement.

A supersession happens when the maker revises a fuel pump core and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 31111-C1100 we list the current reference; ask our desk for written confirmation before a large order.

Export packing is a neutral carton with inner protection; custom labels, barcodes and box specifications are available for volume orders. Shipments move FOB Guangzhou or Shenzhen, with CIF and DDP terms negotiable.

Incoming batches pass a dimensional check, a material look-up against the electrical & sensors specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Aftermarket fuel pump core comes from tooling houses that hold the original drawings or licensed equivalents. KingMay sources from vetted factories and inspects each batch; the manufacturer name is available on request where your market requires origin documentation.

KingMay supplies OEM-grade aftermarket parts built to the 31111-C1100 factory specification: material grade, dimensional tolerance and surface finish follow the original tooling. They are not dealer-boxed genuine parts, and we quote them that way so there is no ambiguity at customs.
