On my 88 5.0 there are two vaccum lines on the back of the upper intake one gets connected to a line that is on the car but the other one goes where? Does it go to the BBK fuel pressure regulator I have, or does it go to the BAP sensor on the fire wall??? And if doesnt go to the BAP sensor then where is the line that goes to the BAP. I really need to figure it out. Thanks
