Iv red allot about this, alot already I'm wondering where the vaccum gos into the dash mine is just gone! I wana no where I have to run this new line everything else is there just lost in the mix! Sux when ur car has ac like a new f150 and you can't feel it sux and I no I'm so close
There is a line that runs along the pinch weld on the fire wall to the tree that the brake booster is hooked too. check and make sure that line is connected with no breaks or creases in it.
I found what you was talking about the hole line was gone so I found the motor the yellow line runs to vents only from tree for a quick fix! Why does the vaccum get weak at acceleration? The line strong and brand new thanks 90lx
