Yep..all you need is the unit, two lines, and a tee to tie in the return...super easy...

use everything from a 3/4 ton but get thebooster from an escalade it will have the studs in the right place. the hds have one in a an odd place so extra work. im in the process of acquiring parts to convert mine because i have no vacuum in my truck at low idle

That's wierd because mine did the exact opposite after my cam. I got a vacuum gauge and it went from 22-24 at stock to about 12-15 now (at idle). I hardly have brakes because of it. I'll try searching and see what I can find out.

That's not opposite that's the exact same. Bigger cams with more duration/lift/overlap cause low idle vacuum and stiff vacuum assist brakes.

Or a Denali like mine...it has hydraulic assist too. The downer from this system is that on low speed maneuvers where you use a lot of steering input and a lot of brake application none of it works that great because your strapping the pump. There may be different pump options.

Or, you can install a vac canister to store vac when you're not needing it for brakes.
We put a healthy cam in my brothers 4.8L, he would have lost brakes if it wasn't for this device that is on the booster. It's a 9" or so electric canister that turns on when the vac is low. It's never come on before, it's never had to, but now it turns on and off, kind of neat on a stock truck.
His is an 04 4.8L longbed, like a work truck, so that's why it probably has one.

Also, my '05 avalanche has hydrb., that's another donor truck you can pick from.

later,
