I have recently taken on the task of replacing the intake manifold gasket on my 1991 F150. It has a 5.0 in it. While in the process of replacing the gasket, I noticed the EGR tube needed replaced as well. The local parts stores all say I should check local junk yards because they can't order a new tube. I would rather put new parts on my truck. Would anyone happen to know where I might find a new EGR tube?
