TB hose question

Does anyone have pics of the steam hose going into the passenger side of the TB? I found the drawings on Shoebox's site, but I need actual pics. I want to run my steam vent into the passenger side of the TB and hook the drivers side to my upper radiator hose. Are there different IAC housing used between 94-97?

You aren't likely to find a photo.... everyone rips that hose off as part of the throttle body coolant bypass. If you look at Shoebox's exploded drawing for the 95+ coolant hoses, the only piece between the steam tube and the throttle body nipple is the 90-degree elbow shown as part #4.

That is exactly what I am looking for. I need to find a part number for that hose. It is molded and regular 3/8 hose wants to collapse. My IAC housing has a nipple pointing toward the front of the engine. Is there a different IAC housing used on some years?

There actually is someone with one still in place

On the lower coolant plate/IAC housing, the 94 plate has a nipple that is angled more toward the front:

That is how mine is. You wouldn't happen to have a part number for the later style? I tried to get my fitting out to no avail.

Why not simply get a short length of the correct diameter rubber hose, and connect the end of the steam pipe to the 94-style nipple? There is nothing that requires you to use the factory "elbow". Better than that, why not just run a line directly from the end of the steam pipe to wherever you intend to connect it on the upper radiator hose, bypassing the throttle body like 90% of the people here have done?

Not any more its not! I took the above pics to ask some people how to get the damn thing off. I ended up cutting it off.

I am trying to keep the TB hoses functional. I am having problems with my car stumbling when cold. I hooked the hoses back up(in an awkward way) and now my car doesn't stumble. I tried a regular piece of hose and it keeps kinking.

Thanks for the pic. I found the hose at the local parts store. Does anyone have a part number for the IAC housing?
