Probably, yes, but like a lot of things like that, they shouldn't be too
expensive.

Probably not for long. Get the new parts, and do it right.
There is also a particularly vulnerable plastic elbow/tee at the rear
end of the longer hose, check it out before ordering since you might
need one of those, too. And a third hose that goes the rest of the way
to the intake boot.

Pretty much - but only the top half of the IM. Undo air boot to
throttle body hose clamp, undo five bolts, remove fuel hose minder and
flip it over. Not too hard, really. Cover the lower half IM openings
with a rag while you work so nothing falls in there (which I did not do
til late in my recent injector/lifter job).
