I have a 1980 GMC Sierra Grande with a 350 5.7 and I can’t figure out where these two hoses connect. The longer hose goes to the gas tank and I don’t know where the other one connects to

the one from the tank is a vent. It would run through the charcoal canister and the other one ran to the intake. The goal was to keep the fumes from venting to atmosphere. It isn't necessary for the vehicle to operate, but you will notice a gas smell without it.
