Neptune Trident ACM - Hose lengths

[Alexr54]

Can anyone who has a Neptune Trident ACM please share with me the internal side (black) hose length for the sample hose?
The internal hose part got ripped and its basically wasted. I have replacement hoses but as far as i understand the sample side is very important to have a specific length for accurate readings.
TIA

Did you ever figure this out?

it's 5ft in length, but I've found in my experience with it, that the length did not matter for my testing accuracy.
