I've had an issue develop three days ago. My bulk diesel tank was empty and I was waiting for my suppler to come fill my tank.
My ZD1211 was already loaded on my trailer so I stopped at a gas station in town and filled both tanks.
The mower ran fine for several hours then, while mowing it just stalled like it was out of fuel. I finally got it started and back to my shop. The left side tank was empty and the right tank was full?
I filled the left tank again from my bulk tank and it runs fine again?
Until I saw this post I was assuming a plugged fuel filter from the right tank. Now I’m wondering?
I'm calling my dealer Monday to see if there is any info on a recall or others .. with same problem. FWIW .. mine has 309 hours.
BTW .. my bulk tank has a Golden Rod filter. I assume the gas station diesel pump does as well. When the problem started it had only “gas station” diesel in tanks.
