Oil & Fuel Bleeding the fuel system on a Kioti

[DieselBound]

KanakaRick, I'd figure that turning to "Air" would do the trick. However, if your fuel bowl is full then I'm not sure that would do much for you, especially if you've sucked air into the pump. Pretty easy to just crack an injector line (put a rag in the area to catch fuel*) and then crank (intermittently) until you get a good stream of fuel coming out (by which time the engine should fire up- and run like crap until you tighten the injector line back up).

* You should be able to get any diesel-rated fuel line. Take off a hose and use it to spec replacement. You'll need to snake any new line through that hose protector (spiral metal). AND, don't allow fuel is seep on to other hoses- always wash fuel off otherwise it'll eat those other hoses.

Don't talk to me about zerks! I had a bad zerk day! (needed to replace a zerk and I have no metric ones!)

Good to know because I need to replace the fuel filter and right now there is fuel leaking out of the fuel bowl, right around the rim of it. I didn't want to take it apart before I knew exactly how to
put it back together. So, let me get this straight... use the "air setting" or loosen the nuts at the injectors to burp it? What about that round thing in the lower right of the picture- is the "air vent cock" noted in the manual the same thing that is in my photo? Is there an adjustment on my machine other than at the valve and at the injectors? Or is the round thing on my machine something different?

I have no idea what the petcock is doing there, but I'll guess. I "suspect" that one turns it "Off" to remove the fuel bowl (and then change the filter) and then turns it to "Air" when the fuel bowl is back on and turns it to "On" when fuels starts to come out ("Air" position results in fuel coming into the bowl and pushing air, and eventually fuel, out some vent port).

If you didn't get air into the injection pump then you shouldn't have an issue. But, IF you did then cracking an injector would be the way to help purge any such air.

Any idea what the round thing is downstream from the filter? Is that a fuel pump or ????

Might be associated with fuel return lines?

Hi KanakaRick
You are right that is the fuel pump. On my Kioti the manual says there is an air vent on it, but there is not.

Thanks Mark. Appreciate that. So I guess I bleed by the air pitcock and by loostening up the nuts on the injectors. My tractor is just turning 1000 hours. It runs good, should I add any injector cleaner to the fuel?

Hi KanakaRick
Don't know enough about them to have an opinion worth anything. However, the collective knowledge on the forum blows me away. Perhaps one of our more knowledgeable posters can weigh in on the value of fuel additives, injector cleaners etc???

Here is a little trick Kioti lovers. This is how I change fuel filter without ever bleeding the system or even turning to the air position.l
Here are the steps:

Clean around the fuel filter and valve assembly. GOOD and clean. and turn the fuel valve to OFF

Unscrew the ring slightly and prepare a clean "tupperware" bowl, or "glad" food saving container or some clean bowl like container. Very clean
Now take this container over to the fuel bowl and hold it under it and continue to unscrew the ring with the other hand.

Let the fuel bowl and dirty filter drop into the bowl. There will be spilled fuel, but it is all caught in your bowl. No mess.

Now take out the messy filter and lay it beside the fuel bowl. All of this is still contained by your bowl.

Be mindful of the spring on the bottom of the filter and check for the O ring on the neck that goes in the filter is still there.

Put in your new filter with the spring on the bottom, and then carefully fill the assembly with new diesel fuel. I use an old injector cleaner bottle full of clean diesel.

Then carefully raise the bowl up and let it overflow into your catch bowl.

Carefully tighten the ring and wipe off the fuel bowl and turn back on the petcock (valve) to ON

Fire up your engine, and it should purr like a kitten, NO stuttering, no bleeding, no nothing.

Empty the remaining dirty diesel into your "used oil" can. Go on with life.
