I don't know the exact name for it, but I need a replacement rubber hose/tube that is basically a 90 degree. A tube runs above the intake manifold. The 90 degree rubber hose attaches to the tube and into the plenum. If anyone has a detailed map of a 5.7 engine it would help me some or if you know exactly what I'm talking about Please tell me.

 

I think you're talking about the purge vacuum line. Most auto parts stores will carry 3/8" emission elbows which is what I think it is.

 

Are you talking about the PCV hoses? One goes from the valve cover to the throttle body on the passenger side, and the other goes from the valve cover to the intake manifold on the driver's side.

 

I looked at it again yesterday and the hose/tube runs under and across the plenum.

 

That sounds like egr solinoid vacuum lines. Heres a pic. The long line with the 90 degree runs under the plenum to the bottom of the throttle body and the shorter line with the 90 degree goes to the egr valve. The bigger piece attaches to the egr solinoid. This what your looking for?
