     1973 beetle didn't have a tube going to the oil cooler.
The air filter just sits on top of the carb, and it will have
it's own way to be fastened, it has one tube about 1/2 in
dia. going to a little hot air scoop close to the muffler, a
small hole in the rear engine pan will be where the tube
fastens to the air scoop. if it doesn't have this any more
then plug the one hole on the air filter. This is a cut and
dry mount, even a cave man could do it.
     On some models the air filter housing had two small
preheat tubes, they both hook up the same as above
but have two holes instead of one.
     The small preheat tubes carried hot air to the carb,
but didn't work. However we still installed the tubes
for looks and to keep the owners from asking questions.

Yep sure do, it slides on a tube next to the oil filler cap,
then to the filter if it has a place for it. If it doesn't you
need to look for one that does, That is the crank case
breather, without the tube connected it will blow oil in a
lite mist around the engine, Hooked to the filter the crank
case fumes are sent down the carb and burned. That picture you posted is like the little chrome jobs we use to
use way back when. they do work some what, but they
seem to dirty up the small filter ring a little fast. so you
might want to find where you can get replacements.

It's nothing but a piece of tube, looks like a heater hose but smaller, and about a foot long. It should slip on a nipple
sitcking up at the oil filler cap, and slip on a nipple on the
air filter. It also has to be made of a material that oil will not
soften. Usually any type auto hose for the engine should
work.
