ok. Let us know how you make out. I can get you a tank and mounting grommets if push comes to shove and have it sent to your dealer or directly to you..
Price quoted is $323 w pump and grommets and is a warranty item if tank has not been compromised with something like underbrush or branch contact.
Your dealer should have the same access.
I asked my dealer if there is an inherent problem w these gas tanks and he stated he has never heard of any and of the 10 Tym sourced tractors he has sold in the last two years such as your model run, not one has been brought back for this.
Not following your post...the original tank is gravity feed and located at the rear of the tractor. The tank and pump you mention; is that a tank which does not mount on the rear of the tractor? I have a 2645 cab model.
Thanks,
Chris
