OE 31112-C1100 — Filter Fuel Pump for Hyundai

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 31112-C1100 to confirm the right replacement.

Position depends on the platform. On most Hyundai applications the filter fuel pump sits on the cooling system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Aftermarket filter fuel pump 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.

Three checks: the code printed on your old part must read 31112-C1100; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Wholesale pricing for 31112-C1100 depends on order quantity, surface treatment and packing. Standard references are quoted ex-Guangzhou with tiered pricing from 10 pieces upward — send quantity and destination port and a quotation usually returns within one business day.

The Related OE References table above lists the alternates we see most often in trade inquiries. Cross-references work because the engineering envelope is shared across the cooling system family — always confirm dimensions and connector layout before you swap.
