Bill, if your engine is like my Universal (AFAIK, all the current Universal engines and the mid-sized Betas are marine-ized versions of Kubota diesels) there is an electronic fuel lift pump that supplies low pressure fuel to charge the injection pump. Once the engine is started, the injection pump will actually suck fuel through the lift pump. If your engine is like mine, shutting down the "ignition" would not stop the fuel flow.
I have a primary fuel filter (a Racor) up stream of the lift pump, which is gravity fed from the tank. There is a shut off up stream of the primary filter, so I can shut off the fuel when changing the primary filter. Only two things stop a diesel once it is going - stop the fuel flow or stop the air flow.

Had a broken spring in the injector of my Kubota, engine ran up to 3 grand, even shutting the ignition wouldn't stop it. (This also de-activates the fuel supply solenoid, no manual shutoff) Thank god the governor worked. I ended up ripping off the fuel hose as I apparently couldn't think quickly enough to plug the intake. Then my buddy, who teaches solid model printing , 'Printed' me a little plastic paddle, complete with instructions to place over intake of engine to shut off engine. So, now it hangs in my engine compartment next to the intake! Bill Coleman C&C 39 animated_favicon1
