39 Baby Mack Posted May 26, 2013 Share Posted May 26, 2013 Here's what the old Mack injection lines used to look like.They had special ends fitted to the ends of the tubing they were not flared from the tubing.The last lines I can remember getting from the Mack Co. did however, I believe, have some sort of flare formed from the tubing.This was around 2007 and the first things I said when I saw these were---how cheap can you get and these things will never work!They did work I don't know how, sure don't look like much compared to the old ones.Even though these newer ones were flared they're still not something that you can make yourself at least not that I know of ?Ron Quote Link to comment Share on other sites More sharing options...
41chevy Posted May 26, 2013 Share Posted May 26, 2013 yep.... just regular thin wall tubing, will take delivery fuel pressure but not pump to injector pressure...BC MackOnly 75 to 100 psi in these lines, they are for the 8 injectors on my 2.3 Mustang 4 cylinder. I showed them for an example of the fitting set up. These fittings and collars are aluminum but they are also available in stainless and ultra high pressure steelThe flares that replaced the lines 39babymack shows are an inverted flare the is a 3 step process and requires a press, the dies and the arbors to make the flare and the Go / NOGO gauge to check the end result. The originals were made with the sweat brazed fittings because the tooling and technology to do the line flares was new in 1938 / 39 and mainly in the Aircraft industry.
