Air horn to the air brake system
#17
Usually there's a manifold on the firewall which you can pull air from..
Using the governor line is not how its done. But it's just a big pickup so I don't expect any ones going to care. I think your problem will be the compressor cycling when you hit the horn. The wrong dot officer could make it a problem if they catch it.
Have fun

What will shut him down is using hose clamps to splice or make any connections. He somehow cannot maintain air pressure.

The reason no one would plumb a horn like this is simple.. You've just compromised a crucial braking system.
There are other sources for air that won't have side effects if the horn valve, or any of your hose, or fittings develops a leak..
Dot will probably never find this.. I was struggling to find reasons to support doing it the proper way.
It's for fun so if it is a big deal to redo it, dont, you'll probably have equal fun either way.

I completely disagree! The fact is that the rate the compressor compress is not linear when in fact it's parabolic.
Explain to me how drawing air from the reservoir as opposed to the governor feed is any different to the brake system.

Dot would get involved of you were in a crash causing injury or fatality. A post crash ingestion would be done. Brakes would be looked at very closely. Push rod measurements, thickness of friction surfaces, condition of the drum, and functionality of the air system, including tubing, connections and compressor.
If you want to argue, fine. You screw up, it is on you.

Usmc, I'm not sure what you ment with linear or parabolic. I was commenting on your thoughts that the compressor would shut off at 120. It will not without that signal line you're messing with.
Here's a scenario (this may be hyper dramatic but it demonstrates the point)
Your new plumbing somehow kinks the governors supply line due to shotty installation. The compressor never unloads because of this kink. The air system continues building pressure fast as youre racing down the freeway. The system reaches 200 psi and the plastic hoses closest to the supply start to melt from all the heat being pushed into the system by the over loaded compressor. Then pow multiple lines blow, the brakes lock up, your truck flies off the road and into who knows what because of the sudden lock up.
All because the governor supply was teed off and not secured properly.
It's your truck, and I really don't care what you do. I just saw this and thought you may want to know it's not correct. If you're happy and feel good about it then run it. Trust me, there are far worse plumbing issues running around on the road right now. I'm sure you'll be just fine.

I suggest you brush up on your physics and math. Please see attached diagram and link to this response. I'm sorry for starting this thread and not doing my own due diligence and thought. I don't appreciate being told my work is shotty. May I also remind you the general public uses the equipment I service more daily than any other form of transportation daily. I wish you well.

No, you had advice on how to do it properly. You ignored it.
