72' fuel tank vent canister
I have a 72' in cab fuel tank and I need to find out how the vent line is run to the charcoal canister. My truck, a 69' but there's a 72' tank in there. On the passenger side of the tank there's a fitting for a vent hose. Rumor has it, that it travels upward the side pilar, eventually ending up in the engine compartment attaching to a canister. Is this true. Any help and/or pics would help. BTW, plans are to keep the tank in the cab. Thanks in advance.

No it makes a U shape up in the pillar, there is a seperate line that runs through the floor and goes up the frame to the canister.

Re: 72' fuel tank vent canister
Is there any other way to run this line to provide venting for the fuel tank. If I cap it, is there a vented cap made for the 72 tank. Seems the 72 tank neck is smaller than the 67-71 tanks. 2" neck on the 67-71 opposed to a 1-1/4" neck on the 72'. Other than changing the tank, are there other options. Thanks.
