I have a question about the proper routing of the diesel for a Kubota 17KW generator.
It currently comes down and enters the fuel filter, then to the fuel pump then the injector pump.
I thought it should possibly go to the fuel pump first then the filter and on to the Injector pump.
I could not see a diagram anywhere I looked on the net.
Thanks for any info.

I am not sure about yours but the 14 kw I have is the same way.
From the tank to the filter then to the pump and on.

Thanks for the input,I'm sure that they would all be the same then.
We we're having it shut down on us and I thought someone had plumbed it wrong before I got it.
We replaced the filter and also the ones for the 6v92 and it works now where as it was running for about 45 minutes and then shutting off.
I was still concerned that it might have been plumbed wrong.
( hows that for a thanks!, got kinda winded there a little! :D)

My 15kw has a primary filter before the fuel pump and then to the secondary filter and then to the injection pump
If it continues to shut down, you should determine why. It probably has protective Murphy shut-downs - low oil pressure or high coolant temperature. On my past generator, I had to modify the wiring to activate lights, to tell me what was tripping the Murphy relay. In my case, it turned out to be large road impacts that released the relay.

Good ideas Ed, Currently it is not shutting down once we got the filters changed out.
I know that it is supposed to shut down
before before completely draining the tanks, but what is the means that will shut it down?
I have heard that it is due to the intake being a few inches above the main engine intake, but wouldn't this require constant purging of the fuel lines each time?
Seems that there should be a better way to shut it down, like via the Murphy switch instead of starving the engine.

Not sure about your generator, but our 10 KW PowerTech with a 3 cylinder Kubota has an electric fuel pump on the generator. A jumper wire from the battery postive post to the fuel pump for a couple minutes will prime the sytem. I can also achieve this by holding the start switch in the preheat position for a minute or so (although this also heats the glowplugs).
Besides, if you monitor your fuel tank level (and know what level the generator quits getting fuel), you should not need to worry about this LOL. Monitoring tank level can be as simlpe as sticking a rubber hose into the tank until it touches bottom. Jack
