You can leave the coupling on. Just use the straw to blast away the crap in there. As for the hose you can probably pick it up anywhere unless its a pre bent piece or something.

That little hose under the throttle body caused me about a day of head scratching wondering what we did wrong when I put new heads on my truck... truck would run good down the road, but idled like crap, reving, then almost die, over and over. I kept hearing a vacuum leak and found it had pretty much dry rotted in half from where it goes near the exhaust.... I just found a new piece of rubber gas line (because the original had that printed on it) and runs like it should now.
Oh yeah, I cleaned every bit of my intake while it was all apart, you should see how gunked up they get down in the ports near the intake valves. Had to use paint stripper to get all the crap out of the ports, didn't seem to damage it at all, but that is the only place I used it, the rest used the regular throttle body cleaner, whatever kind walmart had.

could I just leave the TB on while i spray the TB cleaner into it? Would it be good to spray it into the intake manifold.

My ford manual says to use mild soap and water. The TB has a teflon coating which could be damaged by using chemical cleaners.

Anybody else notice that warning?

If there is carbon in the throttle body, the teflon coating isnt working. cleaning it with carb clean wont hurt the coating anymore than it already is. atleast thats my theory

Well I heard about that after I had cleaned it with a spray chemical so if mine had it then it was gone already.

dont use carb & choke cleaner on the TB, it will eat away at the coating and can make a rough surface for future build up. u can buy a can of TB cleaner for just this purpose.

I ended up pretty much spraying into the manifold. that might have been the reason it had a little bit of trouble starting. but it started and all is good still.
