15/32 size Fuel Line?

I just got my 78 Fiat spider from my dad, but it has been in storage for 8 years and the hoses all needed replacing. I have replaced all the rubber 5/16 and 1/4 inch fuel line and most of the 3/16 lines too. But I have one fuel line I cannot find at the auto store. It measures about 15/32 inner diam (but that may have some expansion from time) and is 14" long. I can't find this hose at IAP either. Anyone know what it is and where can I get 14 inches of it?

That seems kind of big, Where is it located on the car?

I thought this was rather large too. It is from the drivers side, in the back of the engine compartment right next to the fire wall. I'll try to post a picture tonight.

Crankcase breather hose perhaps?

Seems like it may be the heater hose from the heater core to the top of the head. Does it terminate at a spot in the head somewhere around the spark plugs?

Definitely sounds like the heater hose. One of them attaches tot eh carb and operates the choke. As the temp rises the spring inside expands, letting pressure off the choke. Fuel lines are on the other side of the car.

Found it!!!

Got a PDF of the manual, looks like it is just a normal vacuum hose. This is coming from the power brake servo. Thanks for the help everyone.
