The braided hoses and plastic reservoir things? The workshop manual calls those plastic reservoirs "separators." I think it's designed to let air/vapor in and out of the tank safely without letting any liquid gas out. They run to a charcoal canister mounted on the back side of the engine bay, which filters and then vents to the atmosphere. At least that's my (mostly uninformed non-expert!) impression.Why did they install this? Its connected To the fuel tank.
You will want to keep those on the car. If sealed off the fuel tank can collapse. If left open the car will smell of gasoline all the time.Thank you
They are currently not in use. Some pre owner bypassed them. Dont see any use of them nowYou will want to keep those on the car. If sealed off the fuel tank can collapse. If left open the car will smell of gasoline all the time.
Sorry, can you circle what you're talking about in the photo - comparing to my car nowI had 12 different x1/9’s and never seen this on others
Its part of the evaporative emissions control system. If you hook it up properly, your garaged car will not smell like vaporized gasoline after a hot run. These systems were required on cars sold in the USA starting in model year 1974. Similar systems are used is most first world countries.Why did they install this? Its connected To the fuel tank.
That hot air supply hose is a key piece of how the evap/charcoal system works.I have not noticed any fumes despite my charcoal canister being 47 years old. The only mod to my system is the removal of the hose going from the charcoal cannister to the exhaust manifold heat shield (heat shield removed to accommodate headers).
I'll ask the stupid question - where's the charcoal cannister, and how would one know if it needs service?I have not noticed any fumes despite my charcoal canister being 47 years old.

I think that the hot air nipple on the cannister is close enough to the header that it gets enough hot air to operate. In any event, no smell of gas fumes.That hot air supply hose is a key piece of how the evap/charcoal system works.
