My 240z has the SU's with the same tubes. They covered with fuel ine tubes that
run to the air filter housing. When people us K&N filters they either route the
fuei over flow lined to the K&N filter or run it below the exhaust manifold.
When I first bought the car (and was driving it home from the PO's house) there
were short lines attached. The carbs shot out some gas that it hit the hood and
dripped onto the manifold. This started a small fire under the hood. I noticed
the paint bubbling on the hood and pulled over to find the rubber lines on
fire. Lucky I noticed it.
So do not drive it until routed past the manifold or into the air filter.
Good luck,
