Possible premature failure of your catalytic convertors?

Glad I can spell correctly, read "converter" lol. It shouldn't affect a thing then. Is your crossover tube still in place on the back of the cylinder heads?

If you are having trouble getting the tube to reach, I would suggest this part:

List: Catalytic Converter Air Tube - 1984 Ford F-150 | O'Reilly Auto Parts

Without turning off the thermactor air function in the computer, I am unsure if you would run in to problems capping it off or not.

Pay no mind to the "1984 Ford F-150" part of that link. It is a universal part.

Is that just a flexible rubber tube to take the place of the rigid steel one

Correct, you will cut the rubber tube in half, and put the steel tube (with clamps) in between the two halves of rubber allowing you to bridge the gap between the new H-pipe and the pipe coming from the air pump.

I assume that's what your problem is, correct? The new H-pipe changed the orientation of your smog equipment?

It reaches but somehow it came misaligned while installing the transmission and H pipe and it will be a cold day in hell before all that comes out again to align that thing

I would order that part, and use it.

Or you can cap it off, but like I said, I am unsure of how it will work with the thermactor air function still active in your EEC. I'd question where the air goes when the computer is telling the diverter valve to pump air into your cats.

If you decide to use the Walker part, I'd cut some off of the original tubing, allowing you to route it how you want.
