Gas Smell

[nathanmargolis]

Have Backdraft #357 built in 2006 by Vintage and had the car for almost a year now. Previously kept a '69 Stingray in the garage before Hurricane Harvey in Houston for 20 years.

I know carbureted cars will have a gas smell as the Stingray did. The Cobra has one but is stronger than the Corvette by far. This is the only vehicle kept in the garage.

Have checked thoroughly the fuel lines, gas tank, carburetor on a lift and areas underneath the Cobra while parked. Absolutely no leaks. Have check the Holley venturi right after shut down and no drainage. Carb has no signs of leakage. Car runs fine and idles nicely at 900-1000 RPM. Even checked float levels and that correct. Have not made any carb adjustments as car runs fine and want to leave well enough alone on that.

QUESTION: Cobra has real stainless braided fuel lines in engine bay. A reputable engine and high performance mechanic who installed a Vortec blower on a S95 Mustang once owned told me that these type of fuel lines are known to permeate (release) fuel odor even though there is absolutely no leaks in the hose. HAS ANYONE ELSE HEARD SOMETHING LIKE THIS OR HAVE A STRONGER THAN ONE WOULD THINK FUEL SMELL IN A TWO CAR GARAGE? When the car is running in an open area like sitting at a red light, you do not smell a fuel smell.

Appreciate comments.
