This is a new, genuine Kubota fuel injector, part number EG672-44020. Kubota dealer parts catalogs list it for the RTV500-A/H, RTV500R-A/H, RTV520 and RTV520E gasoline utility vehicles. Kubota’s parts list places it in the throttle body group, next to the fuel delivery block. It is a gasoline injector, not a diesel one, and it is not a part for the WG series industrial engines.

A failed injector on these gasoline engines shows up as a misfire, a rough idle, hard starting, a fuel smell or poor fuel economy. Check fuel pressure, the injector plug and wiring, and the spark plugs and coils before you replace an injector.

Specifications

Fits / Applications

• Kubota RTV500-A/H utility vehicle
• Kubota RTV500R-A/H utility vehicle
• Kubota RTV520 and RTV520E utility vehicles
• Not for diesel RTVs and not for WG series engines

Relieve fuel pressure and disconnect the battery before you open the fuel system. On these machines the injector is part of the throttle body group, next to the fuel delivery block. Kubota lists the injector O-ring as a separate part, EG672-44040, so fit a new one if yours is hard or nicked. Make sure the plug clicks home, and check for fuel leaks with the key on before you start the engine.
