Hello Everyone,

Has anyone had a problem with gas fumes on a 67 Camaro, when parked in your garage?

I know the cap is vented. I have a new cap installed, but the filler pipe is original, as is the rubber sleeve that covers it. The fuel line is new #6 AN Hose to a Barry Grant filter, and from the filter to the fuel pump. There are no leaks on the tank, hoses, fittings or the pump. Could it be the seal between the new cap and the old filler pipe? Or does this type of cap just vent off all the time? That would seem odd to me, as it creates a HUGE safety concern. Please HELP me resolve this issue.

Thanks,
Vic

Yes !

And the one that smells worst has a new rubber hose between the filler neck/tank. I think there may be some fumes coming from the gas cap. I have 0 leaks but can smell gas from one of the 67's. Someone else recently told me they had the same problem on their 67.

What about the sending unit, is there a gasket there that could be bad ?

My 69' does the same thing. Brand new tank and sending unit. The system is open with a vented cap unlike the new stuff with charcoal canisters and check engine lights that will come on if the gas cap isn't tight.
I was really concerned the other day when I was welding the exhaust up back there. But it's been in the garage all summer with 100 degree heat and I haven't noticed a "build up" of fumes occuring during the daytime when everything is closed up. I do have a power vent in my attic over the ceiling right above where the Camaro sits in the attached garage so that may pull some of those fumes out/circulate the air.

Only options I really see is to vent your garage.

I would do that if I had fuel fired water heater, furnace, or cloths dryer, not saying electric doesn't make sparks too. Better safe than sorry.

Keeping it close to full may help also.

Don't forget the bowl on the carburetor is vented to atmosphere so that adds to the equation also.

I'm interested to hear what others have to say.

Goodluck, Drew

If this is a recent development and did not happen before I would be worried. If you are a new owner not used to the 30 yr old auto technology experience, it might just be normal. We are used to the newer vehicles that have systems to control the fumes but these old jalopies will never smell like a late model vehicle.

Thanks Everyone,

Well at least it's not just my car. I guess I will install an exhaust fan in the garage. After all, in 30 years I have not heard of one blowing up in anyones garage due to excessive gas fumes.

Welcome Vicburn,

Just go to right hand upper corner of page and click search. Type in ie: Gas Fumes or Gas Tank and hit go. You should get alot of archived post on this subject. I have the problem too it seems to be the rubber hose in line at the tank.
