NH/Ford 2120 Fuel and Radiator rubber hoses: Metric or English?

[grcutter]

Does anyone know if the braided rubber hoses on the New Holland 2120 (late model Ford 2120) are Metric or English?
It looks like the same braided rubber hose is used for fuel, radiator drain, and power steering.
This tractor is now 20 years old and I want to replace all of them but don't want to purchase all the separate segments which is co$tly.

From my measurements, it looks like they are metric with ID = 10mm and OD = 15mm but I'm concerned that this could be thrown off due to stretching over time and there is an English size (3/8") that is also close to this.

Thanks in advance.

Use 3/8 common fuel line for all. The originals are metric but the difference is insignificant.

I went back and tried to measure the pipe and got a pipe OD = 9mm which would be 0.5mm smaller than 3/8".
I'm thinking that my measurement on the rubber hose is off since it has been stretched out.

Is 9mm the correct size?

I don’t know. The tractor was designed and built in a country that uses the metric standard and everything on the tractor itself except for the tire sizes is metric. 3/8 hose will work for all the applications in question. With only a handful of exceptions the two NH dealerships I have worked for since 1996 have used common fuel hose as replacement every time. Cheap, easily obtained and durable. If a half a millimeter makes that much difference, Westchester Tractor will gladly take your money.
