Can anyone tell me the length of the top radiator hose? 134L CJ-2A radiator. Overall lenght would be good I am trying to figure out how long of Aluminum tubing I want to use between two sections of Hose.

Mark, my upper hose measures 13 inches. It is a ribbed hose with an upward bend and I don't know if it is original/stock.I can send a photo tomorrow if you want.

Thats close enough. I am running into trouble finding an Aluminum tube with a bead roll on each end that will work. Seams they go from 6" to 12" 150mm to 300mm Guess I will have to figure out how to roll a bead on a cut down 300mm tube.

Thanks.

The original metal tubes do not have beads rolled into them. Sealing between the hose and the tube depends on the hose clamp only. The outside diameter of the tube is the same as the radiator outlet OD and the hose has to be a very close fit to the tube.

Thanks DonH very little on CHUG is the way it was originally. for instance I'm pretty sure the original top radiator hose was not two pieces of RED Silicone Hose with stainless steel worm drive clamps and a piece of Polished Aluminum Tubing in the middle. But mine will be. I'm thinking I can make due with 2) sections of Hose 4" long and a 8" long tube that would give me roughly 1.5" of clamping surface on each end of the Tube. Now to find the tube. If I cannot find one pre made I will just have to make one up. Was trying to avoid making a bead roller.

I see this is 3 months old, but, I am putting my radiator in preparing for the i initial start up. I purchased(Walcks) a new top and bottom hose. I am not aware of metal tubing required. Is there a benefit to the tubing? Or, detriment to straight hose?

Originally the military jeeps used sections of steel tubing with short straight sections of hose on either end. Made servicing easier.

In my case I am using Red Silicone tubing approx. 4" long with Polished Aluminum Tubing in between. More of a Hot Rod Look then anything.

I finally found someone in England offering a 250mm x 38mm aluminum tube with rolls on both ends that fit my needs perfectly. A little spendy on the shipping but oh well.

Not that it really matters, but....

I was under the impression that the steel tubes were used in WWII to reduce the amount of hard to get rubber. That rubber was needed for tires, not hoses.

Directly after the war, rubber was still hard to get. Thus the continued use of steel tubes. Note the old Willys factory photos of CJs being shipped with a spare wheel but no spare tire.

I believe that the "Made servicing easier." was an unintended consequence of this solution to the rubber shortage.

I had not thought of that very plausible explanation I like it.

  About the same time that the steel tubes appeared, the hood blocks were changed from rubber to wood, the transmission and transfer case shifter boots were changed from rubber to leather, and the seat cushioning material was changed from foam rubber to curled cattle hair, among other things. The Japanese controlled the part of the world that produced something like 90% of the worlds raw rubber.  BW

Gasoline rationing in the US was to save tires and rubber during WWII, we had oil, but not rubber.

Not to mention the U boats hammering freighters off the South American and US coasts. Which made getting materials from SA hard as well.
