i had this pipe lying around, and i'm pretty sure it goes somewhere in the fuel system or vaccum system, just don't know which. please help. need to get car running soon to pay off some bills.
it looks like the tube that goes down between the intake runners . the top has a mounting tap to bolt to the runners near the TB . it connects via rubber hose to an other metal line running across the top of the engine near the 3000 tube to the BOV. the other end connects to metal tubes running under the the intake runners toward the front of the engine and up to the plenum again via a short hose.
