The off road pipe I had for my 5.0 did not fit, it was my fault. I am picking up a Mac off road H pipe today. Does it have the opening for the smog pump tube or not? If so, I had to hacksaw my tube to get the stock piece off. I guess I could rig the tube together for now when I install the new pipe today or does anybody have a suggestion? I know I could delete the whole smog pump but need to know the parts I will need cause I am going to complete this project once and for all later today.

the mac off road h is a good pipe, i had one on my 91 LX...as for your smog pump tube, if you think you can rig it together and seal it up well then go for it, otherwise hit up your local parts store or ford dealer and get a new one...
Here’s some help (a bit late in your case) for removing the air tube from the H pipe...
Try removing the bolts from the upper mounting bracket at the rear of the engine, and then loosen the clamp on the air tube by the cats. Then get a BIG pair of ViseGrip pliers (you really didn't hear me say that), clamp down hard on the tube about 1 1/2" from the clamp and pound away on the ViseGrips. It will come off if you keep at it.
In really stubborn cases, drill a 1/8" hole all the way thru the air tube 1 1/2" from the clamp, put a nail, pin punch or whatever in the hole, seat the ViseGrips up against the nail or pin punch and pound away on the ViseGrips. This is a better method, as you can do the same thing in reverse to put the old tube back on, with some clever means to cover or fill the hole (weld, braze, sheet metal screws, hose clamps and hi temp hose, etc.).
A replacement air tube cost me $44 plus the air valve didn't come with it - another $17, so reuse when and where possible if your money is limited.
