60-62 manual trans trucks - flex hose in clutch line????

[Chuck78]

60-62 owners,
has anyone discovered a source for the rubber section of the hydraulic line on manual trans trucks??? Mine is most likely original, and although I think my clutch problems are mostly due to honing the master bore a lot and still having slight pits in the bore, but I'd still like to replace that rubber flex hose section when I swap over to a divorced clutch master and power brakes. I could probably come up with some type of other hose if needed, if I could find a brake hose with the right connections to use some fitting adapters on (thinking rear axle to frame flex hoses), but it'd be nice if I could just get one that would be the right threads and length to just bolt in, so I could not have to bend a new length hard line from the new clutch master.

Also, a side note, I think my master is the problem with my clutch, as I rebuilt it and honed it out a bit but it;s still got some pits in it. My symptom is that when I hold the clutch to the floor as I creep to a stop, if I hold it there too long, it won't release all the way, which is a huge problem if coming to a stop and you get stuck in gear and stall or can't shift and jam up the linkages! I think I am bleeding off a little fluid somewhere possibly. I also have had a lot of trouble bleeding all the air out of the line, as with a vacuum pump on my brand new slave cylinder, I get a good steady stream of fluid, but I can't seem to get all the tiny little air bubbles out. This led me to think that maybe when I am sucking with the vacuum pump, I am actually pulling some air into the line via a poor sealing master or maybe a leaky hose on top of the bell where I cannot see it. Not sure if this is possible, but I can't seem to get all the air out.

Any support for my theories, or suggestions of other methods or places to look for the problem? I'll soon be swapping to the dual reservoir power master and a reman. 1962 manual master minus residual valve to be used as a clutch master, so if it's the master, that'll solve my problem, but I'd still like to have some support for my theories so I can store that in my memory banks.

Thanks guys,

Chuck in Ohio
