Truck pump procurement starts with a basic distinction: fuel injection and SCR dosing serve different systems. Even when products appear in the same parts catalog, they are not interchangeable. Importers should match the component function, OE reference, engine platform, mounting layout, and connections before confirming an order.

Start with the engine and reference number

For Weichai-powered trucks, the Weichai WP10 pump is offered as a new metal replacement or repair component. The listing identifies 612600081227 and also provides 1001671519 as an OE reference. Buyers sourcing for Sinotruk, Shacman, or FAW applications should submit the engine nameplate, existing pump markings, and clear installation photos for confirmation.

Another option is the 22100-1C201 pump, associated with references including 22100-1C200, 22100-1C201, and 196000-26532. It is listed as brand new, with a minimum order quantity of six pieces and dispatch within four days. Since reference families can vary across markets, physical configuration should be checked alongside the printed number.

Separate fuel injection from SCR dosing

The A0001400578 urea pump is intended for an SCR aftertreatment system rather than conventional fuel delivery. This new, standard-size truck engine part has a six-piece minimum order quantity and a stated delivery period of three to seven days. Connector style, dosing interface, and vehicle application remain important confirmation points.

Distributors can browse the broader fuel pump range or send an inquiry with OE numbers, target quantity, destination, and required delivery date. Complete application details help streamline quotation and compatibility review.
