This is appropriate for right about now (see my recent thread)... maybe I can do this. But we'll see. It wouldnt surprise me if I just replace the boots without checking anything. see if it fixes stuff... thanks for all the info on here. Its helped tremendously...

 

Your other thread was one of the many I saw that made me think of doin this. Be sure to test it first. This tester is under $10 to make. A good set of boots is not cheap and you may be surprised at some of the places you will find leaks if you've never tested your truck before.

There is a post in this thread with the info on the boots I just put on my truck. Not that there aren't many good sources, this was just the best deal I found at the time I was buying. https://www.dieselbombers.com/5-9l-2...l-springs.html

 

If ya replace the boots dont but the OEM ones they are junk

 

And usually more expensive than the good ones

 

Alright I must be missing something here.

This is what I think you do - please explain if it is wrong.

1. Build the gizmo
2. Install as per photo
3. Prime with compressed air (what amount of charge do you run with the compressor - 30, 60, 90 or 120 PSI?)
4. The air goes through the system and if it doesn't hold 20 psi you know there is a problem somewhere.
5. How do you identify the problem? Soap on the boots? Watch for bubbles?
6. How do you set the system to 20, 25 30 and 35 psi for testing? Sorry, I'm a little slow this morning.

thanks

 

you can read yer boost gauge in the cab for what ya got on the system

listen for the leak .....its easy when the engine in off

 

Ok, makes sense. What pressure do you set your compressor to to prime this gizmo?

 

I just use my shop compressor and give it a shot just like fillin up a tire

 

You can fill it up just like a tire with the valve stemm and use either the boost guage or a tire guage to keep the pressure up, or you can use the air chuck and just attach the hose to the tester and set your compressor regulator to whatever poundage you want to check it at.

Keeping in mind that if your using the valve stem you will probably need a second person to help. Even with no leaks your system will not maintain pressure very long and if you want to check it to certain levels one of you will constantly be maintaining the pressure while the other one checks for leaks. This is why I had to find a way of doing by myself and came up with the air chuck. It's my own invention, never seen anybody else use it.

 

Nice job Bubba...
