hi, i just put in an autometer mechincal, boost gauge in my 02 s281 sc, my qurstion i have is, i taped it into the red vacume hose comming off the back of the blower, the red hose going towards the passenger side, its the hose that has 2 ends that run into the back of the blower one side goes to the pass side then another seprete hose comming out of the same hole also red, meets up with a green hose and goes into some sensor. my problem is that the gauge is only reading vacume not boost not sure why? maby a kink in the line any idea's?
