joakcal Posted March 16, 2011 Share #1 Posted March 16, 2011 Hi:I am a new member from California. I have just purchased a 72 Z and noted that there is a slight gasoline or exhaust smell inside the car. I have not found any leaks in the fuel system or the exhaust system. I have had a 73 before and I don't recall having that problem. Does any of you have any experience with that? Any suggestion on what I should check next. Thanks.

Travel'n Man Posted March 16, 2011 Share #2 Posted March 16, 2011 Welcome to the site and the true joy of driving!!Pull your passenger rear quarter panel and your rear tail light panel. Odds are your fuel lines behind those panels are old and brittle - replace and you should be good to go. Exhaust and fuel smells are different......right? Exhaust would be while the car is running and fuel would be while the car is sitting (not started).........all IMO.

StephenJ Posted March 16, 2011 Share #3 Posted March 16, 2011 I could smell a bit of exhaust in the morning when letting it warm up. I replaced the rear hatch seals.....no more smell.

240260280z Posted March 16, 2011 Share #4 Posted March 16, 2011 You can also take the inside panel off the rear hatch and seal the big hole by cutting polyethylene plastic "Vapor barrier" and affixing it with silicone or similar sealant.

esmit208 Posted March 17, 2011 Share #5 Posted March 17, 2011 WELCOME JOAKCALTravel'n Man is right on about the rotted fuel vapor lines. To replace all of them it might be better to drop the fuel tank. One line runs into the deck on the drivers side of the car and attaches to the tank just above where the muffler is and it has an elbow. It is common for this particular spot to rot due to constant heat from the muffler. I have seen people try to replace them without removing the tank but they have horror stories to tell afterwards. Fuel tank removal is generally not a big deal. And as StephenJ said that rear hatch seal can allow fumes to enter as well. Good Luck!

Travel'n Man Posted March 17, 2011 Share #6 Posted March 17, 2011 .............some people say to extend your exhaust tip out beyond the rear bumper............I say "what the hell, it's a sportscar!!" Crack a window or speed up!! Link to comment https://www.classiczcars.com/topic/38906-introduction/#findComment-349533 Share on other sites More sharing options...
Gary in NJ Posted March 17, 2011 Share #7 Posted March 17, 2011 I thought the fuel and exhaust smell were part of the ambiance. Now I have something else to fix Welcome to the club joakcal.

joakcal Posted March 18, 2011 Author Share #8 Posted March 18, 2011 Thankyou for the leads. Will look into the lines, most likely culprit. Ambiance was good until the smell moved from the garage into the house Link to comment https://www.classiczcars.com/topic/38906-introduction/#findComment-349712 Share on other sites More sharing options...
