If you're asking about a Kubota utility tractor, the fuel tank is above the filter assembly and the fuel will gravity feed through the filter when the ring nut is loose and of course you open the shutoff valve. Once the filter housing fills up (and you spill a little diesel), close the ring and then crank on the engine until the fuel gets into the pump. It should crank in less than 30 seconds with the fuel control set at half-throttle or higher. This info is based on experience for a Kubota M4700 tractor.

I believe most of them have a 43 hp Kubota diesel engine in them. However, I'm not sure if they all do.

Well, from what I know, it's a utility vehicle manufactured by Kubota Corporation, America. Kubota is Japanese based company that produces anything from sewage components to diesel tractors and utility vehicles. The Kubota RTV lineup consists of 4 different models. The Kubota RTV 500 (gasoline powered), RTV 900 (diesel powered), RTV 1100 (luxury cab and diesel powered), RTV 1140 (seats 2 or 4 and is diesel powered.) Kubota RTVs feature a hydrostatic transmission with 3 forward gears and 1 reverse gear. The RTV 900 and up feature a hydraulic dump bed and standard 4WD on all models. The RTV 500 has a 2-cylinder gasoline engine that produces 13.5 horsepower. The RTV 900 has a 3-cylinder diesel engine that produces 21.5 horsepower. The RTV 1100 has a 3-cylinder diesel engine that produces 24.5 horsepower, and the RTV 1140 shares the same 3-cylinder diesel engine with the RTV 1100 that produces 24.5 horsepower.
A diesel engine that is starved for fuel will lose prime. This means that you will be unable to start the engine once it has stalled.

It would help to know which model of Kubota engine, and also the application, as small Kubota diesels are used by a number of third party manufacturers for thing such as worksite lighting, crack seal tar pots, etc.

Your best bet would be to get in touch with a local diesel fuel injection repair shop that has a Bosch dealership and give them that info. Go onto the Bosch web site and look world wide there for an authorized dealer.
