Is check engine on? Check for leaking injectors. If you have some injectors that are leaking into the cylinders. Bad injectors will constantly drip fuel into the engine. Some of the raw fuel heads into your crankcase and your exhaust system which can damage the cat.converter. Also check your exhaust flow. If your catalytic converter is failing it will cause enough back pressure to make the engine struggle and burn more fuel.

could also be fuel pressure regulator. check for unburned fuel at the evap canister.

Look for a bad spot, like maybe rust, on all fuel lines on top of the gas tank.
