Tractor Sizing Fuel Line Size

[phatgemi]

Bear with me on the "just go look" comments please. I am wondering the size of the fuel line from the tank to the sediment bowl. This is on a YM2000. I'm not where I can access the tractor at the time but have a leaky hose and would like to go ahead and get one.

I am thinking it is not normal SAE diameter because of a problem I ran into with the thermostart bowl and getting a correct size hose to fit. Is is a Metric diameter??

Someone knowing the correct diameter would save me a trip. Thanks in advance guys as this board is always great for info.

I don't know about the YM2000 but I found the closest match to the fuel hose on my YM1500 to be 8mm. The line from the filter to the injection pump appeared to be the original line so I used it to size the new one. I still can't believe the previous owner hadn't changed it. I bought the new hose by the foot at the local NAPA store.

One of their part numbers is NBHH171.

I'm too lazy to go outside right now, plus its cold and dark. I looked through the Operation Manual, Parts Catalog and Service Manual and none of them give the size. Sorry.

seems like I replaced all of mine with 1/4"
