M37 water fording kit hose

I am trying to locate the proper hose for my water fording kit and I have been unsuccessful. Would anyone know the correct size and length of the hose? I will post a WTB ad also for one along with the correct brackets, but in the event I can't find an original, I would like to start checking different local hose supply vendors armed with the correct sizes.

Thanks
Mike

MWM sells the hose.

Thanks. I will have to call them cause I didn't see it on their website.
