Imperial Eastman Hi-Duty fittings were original. Today they are also made by Parker. I get mine at MSCdirect.com. Search for hi duty fittings. Imperial Eastman still sells them too, but the prices are pretty wild.

Brett, are those flareless fittings? I thought originals were flare type. I just couldn't remember if the nuts were male or female. Thanks Tracy Martin

Yes, they are flareless compression fittings. The ferrule comes attached to the nut, and it separates during installation. The nuts have male threads. The new nuts I have bought work perfectly with the original fittings that I have. The original elbows and tees were forged, but the new versions are machined from bar. That is the only difference that I can see.

The original fitting were male flare with 1/4" steel tubing.

I just got done making a fuel line for my G out of 1/4" brake line.

I use the short male flare nut and 1 of the old nuts.

I have done this on several tractors. Bob
