fuel bowl crack DK35

[Avondale]

Hi My 2006 DK35 had a fuel leak, only when running), the plastic fuel bowl has many small cracks. I shut down the engine as soon as I discovered the source and then shut the isolation petcock. Hope to replace today, question is: will the fuel system need purging?

I didn't on mine last year when I had the same crack issue. I was told to just make sure the new bowl is filled with fuel before putting it back on, though.

Ok, thanks

Don't think so, but if you do, the steps are in the manual and are straight forward.

With what you said happened, you won't need to crack the injector lines. Just fill up the fuel bowl with some fuel and mount it. Turn the valve on the mount to air and start. Run it for a few minutes then switch it to run. All should be good as if you were just changing the fuel filter.

The old style clear fuel bowls were hard and prone to cracking. (I had 1 or 2 do it myself)
The newer style replacement bowls are white and more flexible and no more problems with cracking.

Thanks for the help. I gathered there was a problem as the shop had spares. I got the parts this afternoon and should be back in the game tomorrow.

Did you get the white bowl ?
You don't want the old style clear/yellow bowl, it will just crack again.

Yes, I got a white one. I also noted that my owners manual and my service manual from Kioti does not mention anything about the fuel filter pet-cock having an "air" position, (as mentioned by VictorW in an earlier post). In any event, I will re-assemble after work today and give it a go.

Thanks, James, your picture looks like my machine but not like my owners manual or service manual. My owners manual only has one page in section 5 (Check points before Operations). I do have a picture but no procedure (Para 6.7, page 49) which tells you to clean or replace filter but nothing about the "air" position on the pet-cock. The service manual has a picture of a fuel filter on page 2-15 but it does not look like mine nor does it explain anything about the air position on the pet-cock.

Hmmm. That is from a DK35se manual. Do you have the older DK35? The DK35se manual is glossy and has photo's. Yours looks like drawings.

Yes, mine is a 2006 (Canada) DK35 (Gear).

So does your petcock actually have an air setting then?

 

[Avondale]

Yes, it has 3 positions, on/off/air. One line comes from diaphragm pump, one goes to left side of engine and one goes back to tank (which I think is from the air for venting). Mine is also oriented 90 degrees from your picture. I intend to fill bowl, shift pet-cock to air and turn over to see if It will run, (as mentioned by another post) and then switch to on, if it settles down to normal operation. Please advise if this is not correct. It is still raining here so won't be doing this until it stops. Thanks, Bob.

You have it right. The first time I changed my fuel filter, I had the bowl about half full. I put the valve to air and it started right up. It died after about 15-20 seconds. I just cranked it over for about 5 seconds and it was back to running. Let it run on the air setting for a few minutes. All the air will be purged from the filter/fuel bowl mount. Mine is a 2004 CK30hst but I believe the same bowl set-up was used on several models and years.

Thank You.

VictorW, As you mentioned, it works without any problems. Thanks again. Bob
