I have a Buick century 2000 3.1 and I have a gas leak I already checked gas lines filter ,fuel pump and none of those leak whatelse can I check .... I smell it more on the drivers side in the hood what...

Check the EVAP system - the smell may be coming from it. There is a vapor recovery canister that may be cracked, full of gas or with a bad tubing connection. As part of the system, there are also usually two vent valves to relieve vapor pressure in the gas tank - one on the engine and one towards the rear of the car. If you have a loose connection or one is stuck open, you can get that smell.

I have a 2000 Buick century 3.1 I smell gas when it starts but can't locate where its coming from I changed the fuel filter hoses and checked the fuel pump it smells like its coming from the hood

You may have a fuel injector that is leaking tiny amounts of fuel at the connection to the fuel supply pipe that sits over the fuel injectors, check there and replace any seeping "O" ring seals that you find. There should be stains from any fuel leaking, look carefully.

2002 Buick Century fuel odor

The oil pan is on the bottom of the engine, so any oil leaks from the top or front of the engine could drain down and look like an oil pan leak. It's important to verify that there are no other leaks before having the oil pan resealed. Repair cars by diagnostic tool.

Gas smell coming from car. after its been running especially. When car is parked in garage after its been running garage smells like fuel

Then it is leaking fuel from somewhere. Check all of your fuel lines on the bottom of your car and check the lines under the hood.

Poor gas mileage

Do you have a gas smell in vehicle if you do there check and make sure that you are NOT loosing gas by a leak in the fuel line that was replaced or anyother part of the fuel sytem for that fact. If there is NO leak then the pressure from the pump may be too high and therefore dumping too mucj fuel into chambers but if this is true the vehicle may have a hesitation on take off or may run a little roughand a rich burning smell from exhaust, Check these things out make sure that the fuel pressure at the injector rail is correct refer to your repair manal for exact specs,because I NOT sure what it its, good luck and thanks for using FIX YA

Gas odor when at stops sign or parking in garage

I recently had the same problem. It turned out that the fuel regulator on the engine at the left side just above the intake manifold had an intermitent leak. The gas leaking was not always visible so I had the regulator changed and that solved the problem.
