Fuel tank parts fell off CS2210

I don't know if anyone else ever had this problem. It looks like hard rubber parts fell off the fuel tank on my two-year old Kioti CS2210.

I found one of these hard rubber "donut" bushings on the ground under my tractor, and the other lodged in the rear linkage. They have an OD of 2.5 inches, and an ID of 7/8 inch. I also found the hard rubber rectangular block on the driveway under the tractor.

From the service manual, it looks like the two donut bushings sit on the top of the fuel tank, on both sides of the tank support bracket. The rectangular block sits just under the fuel tank, on top of the transmission. All are intended to protect the fuel tank from damage.

My dealer confirmed what they are, and said to bring it in for a no-charge warranty repair. It looks like they will have to strip the machine all the way down to the fuel tank just to glue them back in place. There's only about 1 inch clearance above the fuel tank.

I'm glad I don't have to pay for it! Cal

Here's a repair update.

The dealer said the vent in my fuel tank cap was blocked, and that the tank was contracting from negative pressure as the fuel was being pumped out. When the tank contracted, the bushings became loose and fell out.

The dealer replaced the fuel cap and reinstalled the bushings under warranty at no cost. I'm surprised that I had no other symptoms with a blocked fuel vent. The tractor started and ran just fine. But I'm sure the dealer must have been right.

I can't imagine that you would not have noticed a rush of air into the tank every time you removed the cap. Perhaps it equalized as it sat for a week waiting to be refueled.

I've had carburated engines that would only run for 30-60 seconds with a failed cap, perhaps the fuel injection overcomes the vapor lock.

That's what the dealer suggested. He said that the fuel system was strong enough to keep it running even with an unvented tank.

I had no symptoms at all. I did notice that the fuel gauge read nearly empty before I brought it in, and after they switched the fuel cap I suddenly had nearly half a tank without adding any fuel. I guess that was a symptom after all. Cal
