Good question, I looked at that on my TX2140 as well. About the size of a fuel line?

Isn't it the thernostat bypass hose?

I don't know if this explains it, but old Yanmars had that lower hose with a drain cock that seemed to be designed to assure the block got entirely drained when the radiator was drained for the winter. Ditch water is cheaper than year-round antifreeze! Back when the owner manual described this, and running without a battery. Both 'features' aimed toward the rice paddy farmer who used the tractor for rototilling only a few days per year. (The tiller was in some cases semi-permanently mounted, not 3-point.) Thermostat? No thermostat, in my ancient Yanmar.

So you might be seeing a 'feature' that's a holdover from an ancestor model.

Here is a picture of that braided water line on my TX2140F.

goeduck, I've got that exact same line on my TYM273 and I just "assumed" it was for completely draining the block whenever one was to change out antifreeze. I have no other answer for you - wish I had one for myself!

It makes sense that line would drain the block when draining the radiator as others have said. Sure are good little engines.

I don't know that a fuel line would not be a good replacement.

I use sections salvaged from a Craftsman premium rubber water hose that got mowed for lower coolant lines of that size. I think they are actually superior to OEM, and FREE.
