Tight Turns and Gas Smell

[lespaul]

78 SC.

When I take tight turn and push it hard (interstate on-ramp), I get a whiff of raw gas. This even occurs with a half tank. Is this common and/or dangerous?

You could have a small leak. Mine had similar situation and I was told its normal for an old car... until one day I turn on the car and fuel is pouring on my garage floor.

Should be no smell.

Check your gas cap gasket and rubber hose clamps on the tank filler neck.

Brad,

My situation was similar and it ended up being the gas cap, which I replaced and all fixed!.

Replace the "crush" seals for the fuel filter.

I have the exact same problem with my 82. I think it could be some of the vent hoses around where you fill up. Happens with partial tank or more with a full tank.

Had the same problem. Replaced the vent hoses that are connected to filler area. Kind of a pain to replace but only took about 30 minutes. After that no smell at all.

I'd suggest making sure your replacement isn't a Cohline hose, or budget to replace it shortly if so. At least a couple of us have found Cohline hoses between one and three years old that were leaking. A search of the archives will turn up details...

Thanks guys. I had purchased a new gas cap a while ago, but I think when I turn it to "tight" the seal is compromised. Yesterday, I filled up and turned it so it felt sealed buy not turned 100% of the way. 3 hours of hard driving and no smell so far.

Just take the gasket out of the cap, put something... rubber, cardboard, plastic.. cut in the shape of a gasket in with the gasket on top of it. You just want to make it a little thicker. Simple.
