Oil Hose

Not sure why we need to worry about pressure ratings on our oil lines, as they see no real pressures running to the ambient pressure oil tank. Temp/oil compatibility and abrasion resistance are the most important factors.

Just look inside the oil tank as the oil dribbles back in to understand how much pressure the hose is under.

I’d be hesitant to use a braided line as it will get super dirty and there’s no way to clean it.
 
Outside diameter of the 9mm line is 15mm. Or ID = .354' or about 1/64 shy of 3/8". OD = .590" or about 1/32 shy of 5/8. It has a test rating of 400 PSI, compatible with gas and oil but not ethanol. Temp rating is 230F. If you feel that your oil is operating at temps above this (in your lines) then you might move on to something else. Something like this which is rated to 300F:

Also interesting. The ID 11/32" which should be OK to get over 3/8" (12/32") pipes. Do you know what the OD is?

I know their PTFE lined nylon braided is .320 ID/ .430 OD
You probably will have to get hold of Summit Racing or Vibrant Performance but I'd bet it's around .500-.600 OD, a lil' bigger OD like the rubber/SS braided lined Summit's house brand hose.

High pressure rated, stainless braiding integrated, PTFE lined. 6AN (3/8" OD - 5/16" ID) and 8 AN (1/2" ID - 7/16" OD) fit well for a Norton application. Plenty of volume with sound pressure containment.
Below is early “dry” routing. The cost between high and low pressure ratings is negligible unless you get into the high end race car stuff.

As you guys noted earlier high pressure rating not needed. I had hose and fittings left over from a Ford 427 build so put them to use on my restoration. There are a lot of sources online that I utilize...mostly once used racing stuff as those guys seldom use the same hose twice between races or engine builds.

I prefer the look of the herringbone and oil leaks drive me bat$#&t.

How do the AN fittings attach to the tubes from the junction block? I like that clean look of using fittings rather than clamps.
 
As Greg Marsh mentioned Steadfast Cycle has what looks like the real deal. Very spendy, but if you only replace it every 45-50 years then not too bad. Here is a description from their eBay store. Part number 06-2201

You will get the brand new Norton Oil line braided hose tubing tube as pictured. It measures 15 1/2", the OD is 0.640 and the ID is 0.256. Genuine Norton Part, very great quality.
 
The AN thread is a particular type of fitting used to connect flexible hoses and rigid metal tubing that carry fluid. It is a US military-derived specification that dates back to World War II and stems from a joint standard agreed upon by the Army and Navy, hence AN.

AN fittings and hose have been used in racing applications since the 60's or earlier.

Follow the links Whiterabbit offered for a comprehensive offering of new AN components.

There is an amazing offering of AN fittings, tubing and hose available.
You can also do a Fleabay search for "AN Fittings/Hose" and find anything you need if willing to do the research.

Earls make adapters too and they are probably a lil' cheaper and made from aluminum. Hard line/tubing to AN adapters=

Swedgelok is a lil' extreme for this application, great for high pressure tho. (I use them because I have a few 5gal buckets of 'em!)

You have, literally, 5 gal. buckets of SL fittings?
I would like to send a PM.

Only problem is that it's 15 1/2". You need two 12" and one 17-1/2" for a 71 or later Commando and 06.2201 is only for 1970 as best I can tell. Of course you could cut it for the 12" but it wouldn't help for the 17-1/2". They do have the German made herringbone by the foot for $19.77/per foot, free shipping, but the OD is not stated.

Yes, I used quite a lot of them at work to plumb gases to gas chromatographs and mass spectrometers, but always for 1/8 inch tubing. Definitely top of the line. It does look like they may make a more compact connection than the Earl's or Russell's ones.

That German made herringbone is the VW fuel injection hose that you can buy elsewhere for about 4 bucks a foot.

Twenty bucks a foot, wow. As rvich noted, there are plenty of less expensive alternatives offering comparable performance.
Take a look at the Jegs and Summit links for starters.
