Could be a vacuum leak but it could also be a burnt gas pump. If your vehicle is taking up more gas then it should be, or your smelling gasoline when exiting the vehicle, that's a sure sign that your gas pump is gone. They're not extremely pricey but they're not cheap either, typical cost would be around $80.00 to $230 depending on what the shop charges and parts. Check the hoses, it could just be a bad / rotten hose.
