View Full Version : Garage reeks of gas, can't find a leak

My car has been in my garage for months and it's never smelled of gas. Now that I finally fired the car up, it absolutely reeks of gas. I have the tank vented, but it doesn't make any sense as to why once it's been fired up it would start to smell. I traced all the lines and I can't find a leak.
The real problem is that my inside a/c unit is in the garage and it's sending in hints of gas. I can't have that. I don't know if it's possible either, but the buildup of the gas smell be concentrated enough so that when the a/c kicks on to cause a fire. That would be devastating. I leave the door open during the day and have a fan on to blow the smell out.
Surely I'm not the only one that has a similar situation. Are you able to seal off the a/c unit or does it need to have a "fresh air" source to circulate? I'm going to be going out to sea soon so the car will inevitably be sitting for some period of time and I definitely don't want to come home to a burnt down house.

When mine was doing that it was due to a leaking gas tank. There was a pinhole leak in one of the factory seams. I removed the tank and sealed it with Red-kote ever since I havent had the smell. Ive also heard of SS braided lines causing a gas vapor smell. Dont know if its true or not but its something to think about if you use them.

^^Is your tank vented?
The only thing that has changed is the car has started. So there is now fuel in the lines. None of the fittings have any evidence of fuel. It's definitely more prominent by the vent, but it engulfs the entire garage with the door closed.

are you running a return style system? my garage always smells like corn with the return and the cell vented

make sure when you vent the tank you loop the line coming out of it, he helps keep vapors in

and your sure that there is no injector o ring leaking that would cause fuel to puddle ontop of the intake?

Yes it is and I never smell gas anymore now that my issue is fixed.

Also reduces the chance of spillage in high G force scenarios.

Do you have an AFPR? I couldn't figure out where my smell was coming from but it turned out it was a slow leak coming from there.

It took me about 2-3 months and removing my tank about 10 times before I found my leak.
I wonder if you parked it outside if something like this would work find the source.

strike a match to search with and when it goes boom you found the leak.

Yea, I have the return style and it's vented. I have the loop in it as well. I guess I can just plug it until I get back to stop the smell and just put the vent filter back on it when I get back.
But it still doesn't solve the problem of it getting into my house.

I don't know if it would or not. I really have no reason to think it was the tank. It should have been doing it the hole time.

Im not saying your tank is leaking. Just stating that was my issue. I think your problem is elsewhere. The fun part is finding it.

You can seal the ac unit to the house up with ducttape. Go for it. I have similar issue when I fired the fourwheeler up in the garage with bad gas in tank. It took a couple of days for smell to get out of there. I would assume the nose of your car is facing out of the garage.

Mines return style with no evap and a vent but never smells like gas even parked in my closed garage for weeks. But Im on stock lines still.

Could be the stock lines keeping the smell down. I run the Fragola push lock lines and i have a feeling thats where the smell comes from. Mine doesnt really smell bad with the key off/not running, i think its only bad when theres some fuel pumpin around in the lines.

For those of you with the gas smell, how do you not smell it in the house?
I taped up all around the inside unit and now it's coming through the door.

We have a laundry room between the garage and the kitchen and as you were walking thought it before you opened the door to the garage you could smell the gas fumes. It was so bad the wife almost kicked the truck to the driveway and IIRC her cleaning lady got sick.

I've got the same thing and it goes through there into the rest of the house

return system here, no corn smell, my SS fuel lines are Teflon though.. maybe that's why..

apparently that's the problem. Mine are rubber. From what I've found out the ethanol in the gas.
"What is essentially going on is the ethanol that is mixed in gas is seeping out. Ethanol is pretty much a type of denatured alcohol so even tho you can not see it cause it is wrapped in ss braided line it is slowing drying out your lines faster than normal. No one had this problem before they started mixing/putting ethanol is gas that is why until a few years ago this was unheard of. So what your smelling is the ethanol leaking/seeping out of the lines. The reason why you dont smell it after a few days cause that is usually how long it takes for the fuel to go back into the tank and then since your tank is metal i.e. steel or alu. it no longer seeps thru. NOW how you fix this you have to replace ALL your fuel lines with Teflon lined braided fuel lines......I know it is a bitch to replace all your lines, but this WILL fix your problem. I did the fix 2 years ago and still NO smell.....Trust me......also why some may not smell gas with regular rubber braided lines cause they do not put ethanol is race gas so that is why if you run race gas you will not smell it."
Fuck that. I guess when I get back I'll be going to a -12 feed and -10 feed and a real tank and pump.

since you guys have all your lines already made, just remove them, and measure, or take them to a hydraulic shop that makes lines. theres a place on cross county that could make me some, dont know the name, but if was right off that main road, or maybe chas rubber can do it. then sell the old lines to someone else... or just say fkit...

I use those same lines, mine doesnt stink when the car is off, but sometimes you can smell gas when the key is turned on and the pumps are running.

That is CESS, Carolina Equipment Something Something. They make alot of hoses for us. Had them make my oil feed hoses for the turbos. They use a high pressure Teflon hose.

Don't know if I agree with that, or the SS braided lines either, nor a single word in the quotes of what 98Camarod posted... Its BS to me...
I replaced my entire fuel system, 100% all of it..
Its been on the car for at least 1.5-2 years now.
Before that, I have been running E85 through my Evo since late 2007 through a rubber return line, the same aeromotive rubber pushlock hose. I would have no issue disconnecting it from my FPR and literally licking the exterior of the rubber hose to show you that its not "bleeding" through the rubber line. (Sarcasm...)
I have a pipe fittings to AN adapters that I used Rector (?) Seal to seal up the NPT fittings, and all the rest are AN fittings. My feed side is -8AN SS braided hose, and the return is -6 Aeromotive Push Lock hose, and I have ran gasoline and E85 through it, a lot of both fuels. Never had a smell of either fuel from the car 90% of the time sitting in the garage.
The only time I ever smell fuel is when an AN fitting has came loose, or an NPT connection didn't have enough Rector (?) Seal on it.
Things sitting for long periods of time are sometimes just as degrading to their condition as it is driving the car. Both gasoline and E85 are solvents that upon sitting on things for some time, they will eventually eat through stuff. If I had to wager on your problem, I would almost say your issue is going to be something that you would say "For sure I don't think that's it" partially due to Murphy's Law, the car sitting, and well, quite frankly, that's how most of working on a car goes.
But then again, this is just me and my sometimes stupid "logic" in my own mind at work.

I'm going to plug my vent line and see if it still does it. If it does, I'm going to have to put the hood and bumper cover on and it's getting the boot outside while I'm gone.

I have all push loc hose and leave my car in my trailer all the time with no smell. I have two fuel cells with 116 in both of them. Both cells are vented also.

I wouldnt do that and drive it very much. It will create a vacuum on your tank.
