How to Install Demco Air Force One on 2024 Jeep Gladiator Rubicon with Hard Vacuum Line

Updated 11/17/2025 | Published 12/12/2024

Question:

i have purchased several air force one systems from yall for my different coaches and tow vehicles. we just purchased a 2024 jeep gladiator rubicon and it appears the brake vacuum line is much smaller that our other jeeps. probably 3/8inch line. where do you recommend tying into this line and where can i get a 3 way fitting of the correct size?

Hello Keith,

Great question, this is my first time coming across this issue. I reached out to our friends at Demco, they supplied me with the 2 pictures of the vacuum line in question. I have also included the portion of the instructions that you need to follow for the hard line. There is also a link to the full instruction below as well. Please let me know how the install went.

Hey Keith, how did things go with tying into the smaller vacuum line on your Gladiator for the Air Force One system? Your update could make it easier for others working with the same setup.
