Cutting Hard Vacuum Line

[JASim]

I am adding an Auxillary Braking System (for flat towing) to a ‘26 Jeep JL. I need to splice into the hard vacuum line going to the brake booster.

Has anyone else done this? Any tips for cutting/splicing into that line?

TIA

There is hard plastic tubing under the master cylinder from the brake canister to a "T". You have to cut it out carefully because it wont pull off. Then you can use the supplied hose, Tee and check valve to replace it. It is very tight but doable. I have an Air Force One on my 24 392.
