Gas Fumes...

First of all… I hope I’m not spamming with all the questions.
The very first thing I’ve been doing is searching through past posts to see if my questions are answered.
When I can’t find them… I post.

Gas Fumes.
The garage is filled with the smell of gas. Not exhaust. Gas.

I can smell it in the house as well.

Are there key places to check on the car for this?
There’s no leaks on the car. Nothing on the ground.

I’m hoping it’s something simple like a worn piece of rubber on the gas cap.

I just fix a similar issue, gas was seeping from the fuel pump

I second the fuel pump suggestion. When I got my car it was dripping out of the center connection of the body of the fuel pump.

Also check all the fuel line connections.

If you have a glass/reusable fuel filter, check that it’s all screwed together correctly.

On the carburetor, check the screw on the side of the fuel bowl. Also, if the carburetor is a model that runs fuel from the front bowl to secondaries in back, check that tube. Sometimes the O-rings and tubes aren’t seated, and it leaks.

Thanks for the quick response.
I just need to find where the fuel pump is. Going to youtube now.

right behind the power steering pump

Also look for it pooling up in the intake, from carburetor leaks. Take a good look under the edges of the air cleaner. Also, look for wet fuel running down the back of the engine and bellhousing.

Just to state the obvious, since you smell gas in the garage and most importantly in the house, roll the car outside and ventilate the garage and house!! Gas fumes are a fuse waiting to be lit by a spark, hot water heater, stove burner, etc…

Next drain the fuel tank into acceptable gas containers.

Now to search for your fuel leak. Look around the fuel tank, are there any signs of black goo? I had a persistent slight fuel smell in the car and when I pulled the trunk mat, there was a black goo in the right rear corner. The goo was the remnants of the black caulking strips that is used to seal the tank to the body that a mixed with gas that leaked through the gas tank seam.

Check the fuel filler neck and fuel filler hose. Next check the bottom of the tank where the gas sending unit seals to the tank AND the rubber hose connecting the fuel tank to the steel fuel line. Follow the fuel line through any clips and undercarriage, grommets should be used whenever the line passes through a metal hole, also pay special attention to the rubber fuel hose connecting the fuel line to the fuel pump as the rubber line (on a 67) runs through a portion of the frame. Next the fuel pump to carb line and lastly the carb.

Personally I replaced everything fuel related a new tank, sender and gasket, rubber filler tube and gaskets, steel fuel line, all rubber hoses used in he fuel system, all clamps, and pump, basically everything except the carburetor.

Good luck but most importantly STAY SAFE!!

Thank you!

An old fuel line doesn’t need to be leaking on the floor to leak enough to smell gas. You don’t say what year car and engine you have, a 67 has 4 pieces of rubber fuel line from tank to carb.

I had a problem with a split seam on the fuel tank. Took me ages to find as I rarely filled the tank. It became evident when I filled the tanks and a small amount of fuel seeped out

Make sure you have fire extinguishers!

Thank you all.
This morning. No gas smell whatsoever.
I did find some oil on the ground and checked under the car and saw oil on the bottom of the oil pan.
I took off the air filter and didn’t smell any gas. Couldn’t find any pooled up.

I literally know NOTHING about cars. So telling me to “check the fuel pump” is like asking me to find a unicorn.

I need to order the handbook you’ve all mentioned.
So much to learn.

Another thing to mention is that, being a carbureted vehicle with modern fuel, it WILL smell more than a fuel injected modern car. When you park it when it is hot from driving, the fuel will naturally tend to vaporize out of the carb and stink up the place. When I get mine home I usually pop the hood and leave a side door open on the garage for a while with the garage door up a smidge, so that the car can cool off and the fumes be drawn outside.
My wife is highly sensitive and smells “stinky car smells” that I don’t even notice. But, too much fumes is a good indication of fuel escaping somewhere, or many places in small amounts.

As mentioned, be safe, and get a little dirty checking over the entire fuel system.

Also, if the engine / drivetrain is very oily / greasy / grimy, that can contribute to the “stinky car smells”. Spend a bit of time wiping up all the grime and gunk. Your car will look better under the hood and stink less. It can also help you find leaks, as the gunk starts to reappear.

Good luck, and keep us posted!

Yeah. The car is right below the living room and it’s not as bad in the morning. Just after I’ve driven it.
Does that sound more like “it’s just an old car… plus carburetor”?

My garage smells like fumes as soon as I get home too, but smell fades away in an hour or so. I have noticed that I smell fuel when I drive when I put a lot of gas in the tank. So I try to keep it under half a tank.

Mine usually fades away in an hour or so too. When I first got the car though it seemed like it would stink forever - which bothered the wife to no end :stormzap1: So I wiped up every bit of smudge and gunk off the engine and trans, top and bottom, and then was able to chase down the various spots that were seeping and oozing. That has helped immensely - except for that hour or so when the car is still hot from driving.
