Power brake Vacuum line? It seams like I only get 2 good power assisted stops before my vacuum runs out. I have the line hooked to the stock place. The LS1 is stock, I have the 12v+ normally closed brake line hooked up but I haven't hooked up the brake light wire yet, the N/Open one. Will that trip open the vacuum line for me? the engine makes good vacuum, 18 to 25, down hill. Do these motors need a vacuum can?
Thanks, I was in Colorado, that's where I found this out.

Re: Power brake Vacuum line? That's the only external vacuum load that my Jeep requires. The braking system is a Dual 9" setup from MP masterpower brakes. I have a call into them also. They ask for 16 inches to run their system. My gauge hits that regularly.
When I saw the wires running to the Vac line that made me think. It could be because I don't have that brake switch setup yet.
All in all the Jeep performed Very well on its 3300 mile treck across New Mexico and Colorado. I did get an error code Map/Baro Low input when I crossed Imogene pass at 13188 feet. It cleared after I returned to 8600ft and restarted 3 times.
Thanks
