Hi guys new to a Bronco have a 1996 xlt just bought it while looking under the vehicle today I see a tube hanging just next to the tranny. Just wondering if anyone knows what this is and where it goes when i trace it back to the 5.0 engine it hooks into what look to me like a reed valve located in the middle of engine by firewall any ideas would be much appreciated .

The 96 302 only had the tube coming off of the smog pump and going into the crossover tube behind the heads, and the egr tube. None of those are along side of the transmission. Only hose I know of near the transmission is the breather hose for the transfer case.
