It should go from the air filter to the valve cover some where. This is part of emissions system. Look for a pcv valve or another type fitting on the cover to plug it in.

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.

Usually if you can smell fuel inside the cabin the vapors are coming in thru the vent system from the engine compartment.
Could be a fuel leak or a problem with the vapor canister.

Strong gas smell in vehicle


Take it seriously! Gasoline as a liquid is not flammable but the vapors are! Have it serviced and diagnosed by a professional unless you are mechanically inclined. If you were mechanically inclined I would assume that your question would have been more specific. Gas vapors can come from multiple sources. The seals/gaskets on the inlet. The vapor emission filter. Broken gas line. Bad air fuel mixture. Leaking fuel rail. Damage in-line fuel filter. Etc.

91 Maxima Gasoline odor when I first start the car


If it is running fine, the busted bolt isn't the source of the gasoline smell. The intake manifold has vacuum, so the smell wouldn't be getting out, air would be going in, and a vacuum leak would give you poor idling. The exhaust manifold wouldn't have much raw gasoline smell. But it would have loud noise if the broken bolt were causing an exhaust leak.

Check that the vapor recovery line is not broken or disconnected. The hose connectors get cracked. If that were broken, it would cause a gasoline smell after the car has been sitting, especially if it has been sitting in the sun, heat driving gasoline vapor out of the tank. It is supposed to condense in the vapor canister, but some escapes if the line is broken. If it is broken, driving would **** out the gasoline from the line and the wind would dissipate the smell.

Or it could be a leaking injector. With the injector cover off, engine idling and cool, you can visually look for raw gas around the injectors and injector rail connections.

Hope this helps.

When I go to fill up the gas tank the gas keeps cutting off at the pump handle and I have to slow the gas pump to a trickle in order to fill the tank.


The problem is that your gas tank "pushes back" like it's full even when it isn't and makes the fuel valve click off. Tom and Ray on Car Talk covered this in a 2007 show and I pasted some of their response below:

"RAY: This condition is probably caused by either a blockage in your gasoline vapor recovery lines or a bad refueling control valve.

TOM: Gasoline vaporizes. How do we know that? Well, when gasoline is spilled, you can smell it, right? What you're smelling is vaporized gasoline.

RAY: And in the old days, when you filled up your tank, all the air inside the tank -- the air filled with gasoline vapors -- came whooshing out through the filler hole or through a vent at the top of the gas tank.

TOM: But then people in places like Los Angeles realized they couldn't see the person standing next to them due to smog. And since gasoline vapors contribute to smog, car makers were forced to install devices to capture those vapors.

RAY: So now each car has a vapor recovery unit that collects the gasoline vapors from the tank and then, the next time the car is started, sends them to the engine, where they're combusted. Your vapor recovery system isn't working, Lottie. One possibility is that one of the rubber hoses is blocked or collapsed."

I overfilled my Jeep Grand Cherokee on my first fill up and now I smell gas every time I fill up. I now stop at the click. I am told it is probably my charcoal filter because I keep smelling gas and the...


The charcoal filter is used to filter fumes from the fuel tank. There is a vent line, that comes from your fuel tank to this filter. (Charcoal canister)

Now since the charcoal filter has been completely soaked with gasoline, it will no longer function as it should. Even with vapors from the fuel tank vent line, the canister only has a working 'life' of so far.
You will smell gasoline in strong amounts until it is replaced.

Can't comment whether it is safe or not. (In my thinking, you are driving around with a charcoal canister, that has a charcoal filter soaked with gasoline. I wouldn't use it this way, but that is just my thoughts)

Gas smell


your brand new 1972 VW beetle may have as simple hole in the fuel line..when the car is not running you will not see any gas leaks becuase there is no call for gas to be fed to the motor.

have someone, or yourself crawl under the vehicle and look fort a small dripping or small stream of fuel.....REMEMBER!!!!!!!!!...gas is HIGHLY explosive and flammable...no smoking while checking/working on the rpoblem...and fuel's smell comes from Naptha, a chemical added to oil to make gasoline, it is a very strong ordor..a small amount can smell like a gallon.
hope this helps you

Gasoline smell from time to time


I have seen a 2004 Grand Am that had a very light leak around one of the fuel injector o-ring seals allowing fuel to seep out onto the lower intake which then vaporize when the engine would get hot making the smell.

Gasoline smell off and on


Have them check EGR tubes, and any hoses, or tubes running to the exhaust. My guess is ones leaking while driving & getting drawn up into the incoming air at the cowl.

Hi have a nice day!
Check EVAP Emission Control System Vent Circuit.

DESCRIPTION The evaporative system prevents hydrocarbon (HC) vapors from the fuel tank escaping into the atmosphere where they would form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Canister Close Valve (CCV) closes off the air inlet to the canister for leak detection of the evaporative emission system. The CCV also prevents fuel vapors from escaping from the canister. When the engine purges HC vapors from canister, the clean air comes into the canister through canister air-filter and CCV. If open error message displayed is "P0447" If shorted error message is "P0448"
