SOURCE: leak onto floor passenger side from neck of ac drain through firewall

It's not your heater core. If your heater core is out it would leak antifreeze. My wife's 97 Grand Cherokee had the same problem. It is condensation from your AC coming leaking through a round hole in the AC unit at the firewall. Pull the carpet back and dry out underneath it, there will be a lot of water and we had to leave the carpet pulled back with a fan blowing on it all weekend to dry out. I fixed this about 8 years ago so if I remember correctly, the was a plastic part of the AC at the firewall that had a hole in it that the water was coming out of, I could see leaves and debris in the hole so I know it was part of the drain system. I cleaned out what debris I could and used a cone shaped peice of rubber and twisted it in to plug the hole and tapped over the plug to ensure that it wouldn't back out with vibrations, etc. After you dry everything off start the engine and turn the AC on max, you'll be able to see the where the water is leaking from after the AC gets cold. Hope this helps, it drove us nuts for a year before we figured it out and the wet carpet smell wasn't pleasant.

Put more in. Keep adding untill it won't take any more. You can't over do it with those cans. It'll either work or you'll find the leak if it really has one.

SOURCE: pushing fuel out the filler neck

Was the fuel check valve recall performed on this truck? These are similar symptoms to the recall in which gas would pump from one tank to another.

How to fix the fuel filler neck


You have to get under the car and look up between the area that the tank filler hose goes up to the cap, if there is not enough area to work, you will have to lower the tank, this means a jack is needed and the tank should be almost empty. There is a clamp on the neck of the filler that holds the hose and you remove that and pull the hose off the filler connection. Then you continue to lower the tank to get to the connection on the tank itself. Remove the hose from the tank and inspect it for leaks. You really should replace it anyway. Go to an autoparts store and get a new hose Permatex high tack adhesive, reassemble the host to the tank and use the adhesive on the outside of the tank connection and slide the hose over that and tighten the clamp, raise the tank back up to get to the connection on the filler and do the same with the sealant. Replace the clamp and finish the tank install. This is not an easy job and that adhesive does not come off your hands.

My gas cap appears new, but doesn't seem to screw on right, check engine light is on


make sure you have the right gas cap for you car, next check for rust on the fuel filler neck threads as this can cause the cap not go on properly.

Gas Overflow


Sounds to me like a bend/kink in your filler neck, or someone stuffed a rag down there.

Remove the fuel filler cap and run a long, rigid wire down your filler neck - if you encounter significant resistance, remove the filler neck from the tank and investigate further.

The hose is on the side of the gas cap and it runs down to the bottom of the quarter panel. When I filled the gas tank up, gas comes out of this hose. We just had the fuel pump replaced. Its not leaking...


There are normally two hose lines from the fuel filler that run to the tank. The larger one carries the fuel from the nozzle to the tank. The smaller one is a vent hose that allows vapors to leave the top of the tank while filling. These vapors come back to the nozzle area and can be vented and/or collected by the nozzle depending upon air pollution standards in your area. If your second hose is running to the bottom of the quarter panel, it is probably the vent hose that may not have been reconnected at the top of the tank when the fuel pump was replaced. The fuel running down there is from kickback fuel at the time the pump shuts off. The real problem is that the vent line is open on top of the tank and when the tank is full, that can allow vapors and fuel to escape out of there and it could contact hot exhaust areas - a major fire or explosion hazard. Have this inspected and repaired IMMEDIATELY.

Gas leaks on the ground when refueling from a blk tube underneath my car 2011 ford tauras


There is a over flow tube that is connected close to the top of the filler neck. It allows fuel to return back to the tank instead of overflowing back out towards you and covers you up with Gasoline. That area could have been in a accident at one time and not been repaired right or a Factory Fault, not likely to be the age of the car.

Emission evaporative system large leak


Error messages like this are typically caused by air leaks at one of several key places: (1) at the gas tank filler neck; (2) at the charcoal canister; or (3) one of the larger vacuum hoses under your hood.

A loose hose is probably the most common problem--over time, the plastic nipples to which those hoses attach weaken and can break off. Thus, a hose can look like it's in the right place, but it's not actually creating a seal at one end.

You can try to listen for this with the engine running and the hood open. Do you hear any kind of a "hissing" sound like you might hear when using one of those spittoon-things at the dentist? That's a major vacuum leak, right there. Many leaks aren't noisy enough to hear over the sound of the engine, though, so don't consider an absence of noise a statement that everything is just OK down there.

The problem at the fuel filler neck was endemic to certain GM vehicles, but it appears in other cars, too. Believe it or not, there's a vapor recovery hose that is attached at some point of the fuel filler neck to catch evaporation off the tank. Some cars also have another pickup right at the top of the gas tank, too. If one of these has worked loose or rotted, you'll start getting strange vacuum readings and a check engine light.

Hope this helps. Finding the cause of this problem usually takes more time (and money) than the actual fix.

Good luck!

Cleaning/changing fuel filler neck on 2003 Cavalier


You might be able to take it off the car and use a wire brush to clean it.
I would not want anything falling into the tank.
It might still be available new from the dealer, or used from a salvage yard. Should just be a hose clamp and the screws holding it to the quarter panel.

GMC Jimmy gas filler neck leak


Replace your filler neck. It's not hard and when you buy the new one, installation should be obvious and rather straight forward.

A fuel leak is not something to take lightly and it will get worse over time.

Most fuel systems are pressurized (that's why you'll sometimes hear a hissing sound when you open your cap) so if your filler neck is leaking it can throw a code.
