Kubota 6030DT dies after 5 minutes

I am also assuming that you are using some anti-gel additive in the fuel; I sure am.

Yep we put in some with the new fuel (not sure which brand she bought).

Yes - may have some water in the fuel. Drain and replace filter(s), drain the tank and lines. Replace with fresh fuel. Check your manual on how you need to prime the system with fuel before trying to start.

No manual as we bought used. Anyone know of a good website to find tractor manuals? All I can find is sites selling them for $100.

Ok so I just replaced the filter and its seals. Had to remove the mount to get the filter off, which meant removing the fuel lines. I was careful to tighten them back so the holes in the bolts lined up in the fuel line (not sure how to describe that better, but under/overtightening appears that it would block the lines). I loosened the fuel line nuts on the injectors, cranked it over, saw a little fuel come out of each lines, tightened them back up and we tried starting but it just wouldn't catch. Using starter fluid it seemed to want to start (some exhaust coming out), but nothing doing. We tried 3 times.

She did put new 5 gallons in there with the gel, but I wasn't sure how much there was before she filled it. Would you guys still recommend dumping it all out? I've never re primed a fuel system, I'll youtube to see if i feel confident doing it.

So I'm not sure how much diesel I'm supposed to see coming out of the fuel lines at the injectors. I'm seeing little dribbles... is it supposed to be really shooting out of the lines?

As for the service manual, you should be able to get one through your Kubota dealer. They will probably have to order it. I bought a service manual for my allis Chalmers 185(tractor made in the 1970's) for about 40 dollars. They had to order it and it took about 10 days and the ups truck delivered to muy door. Make sure you get the service manual and not the owners manual. As for fuel flow you shouof be getting more than a few dribbles. Also, on your diesel fuel supplement I use either hoses or power saver. Both seemed to be good products. You want to make sure you get you mix ratio right. A bottle/ jug of fuel supplement is usually made to treat 100 gallons of fuel. A good mix ratio is generally about 1 ounce of supplement per 5 gallons of diesel fuel. Another trick you might try is to take your wife's hair dryer and set it on high. Blow the hot air into the air breather. This will warm the intake and in theory the air will be warmer going in the intake and help start the tractor. Hope this helps.

That supplement brand should be howes, I don't know why my phone put in hoses.

You may have a fuel filter in in the fuel tank that is partially stopped up. I have got mine to run longer by blowing air back thru the fuel line from the tank, with the fuel tank cap off. I finally took that filter off and am depending on the downstream filter. Has been working that way for 8 months with no problem.
