Kubota EG522-52020 is the new, genuine electric in-line fuel pump for Kubota’s WG-series spark-ignited industrial engines, which run on gasoline or LPG. It is listed in the parts for the Kubota WG2503. This is a gasoline fuel system part, not a diesel lift pump. JLG also stocks this pump under the same number.

A failed pump causes a no-start or stalling when the engine runs on gasoline. Before replacing it, check the pump fuse and relay, power and ground at the connector, and the fuel filter.
