TBI/Intake manifold questions

[KingRaider76]

Hey I have a 91 K2500 5.7L 350 I can no longer use the stock intake manifold and I can't find an exact replacement. Can I use the 2-barrel TBI with the oval or square opening manifolds with the same bolt pattern?

Heads different? You can get a carb intake and then buy a TBI adapter.

The intake manifold in my truck is a 2-barrel TBI. TBI is installed and functional. I have no choice but to replace the manifold. I'm looking for the simplest way to get my truck fixed. Any other questions I need to answer?

Why?

The housing for a connector for a heater hose is stripped out and can't be rethreaded

I think the "why" is what we are looking for.
Did your stock one crack, warp or something? It would be unusual for anything to happen to a stock TBI manifold.
None of us are being a-holes, genuinely want to help.

Well that's something. Never heard of that before.
Do you have any wrecking yards in your area that you can pull one from?
I know the yards around here have access to all the others and can get what you want/need. I'm sure there's a ton available to those with that system.

So it's got buggered threads. Next size pipe tap. Install bushing , to next size down. Then add new hose fitting and hose , clamp . Done.
There's a wide variety of hardware for hose attachment.
