Hose to no-where? Can anyone ID this?
I was giving one last look to the engine bay before trying to reinstall the engine, and notice a small hose that ran across the width of the engine bay hanging slightly loose. I grabbed it to push it back up and it snapped right in my hand. The rubber had turned to brittle. When I traced the hose upwards, I found it was connected to nothing, and looked like it hadn't been for a while. When I traced it down, it ran by the driver's side heater vent hose, and then back into the body at the transmission tunnel. Anybody know what this was/is? The car is a 1974 with an 83 SC engine in it. No cats, and no O2 sensor, in case that sheds any light on it.
Where it snapped at  Following it around the heater vent  Bound to the body  Into the transmission tunnel

It would have connected to the charcoal canister in the engine bay of an SC (right front corner of the engine bay) and the other end to the fuel tank.

And, the car is a 1974 911, not an SC...
Cheers, Captain Obvious. |

Got it, thanks. I don't have a charcoal canister, so if one end of that hose is connected to the fuel tank, does mean gas fumes are being openly vented into the engine bay?

it may not be connected at the other end either. the sc had a vapor tank in front left fender above the washer reservoir. the hose connects to it and from there to the tank. not sure if your car has that.

Hose is fed from the vapor expansion tank which is in the driver's inner fender. Gas tank feeds the expansion tank through a fatter hose - probably through some sort of Y in the tank fill neck closer to the tank than the petrol fill point. I am not absolutely sure the expansion tank is in the inner fender on a 74. but the charcoal canister is in the engine compartment on the oil tank fill side on the inner wall. There should be a metal strap there if the canister is missing If you have a WW squirtie fluid tank in the inner fender and you see another tank in there too - that is the expansion tank.
