well, i have about replaced everything on my 65 tbird ht....i still have a strong smell of raw gas when going down the road especially....obviously it is venting somehow/somewhere in to the car...anyone have experience with this trouble - any suggestions?....i do not see any leaks but who knows?!...thanks johnnyB

Could be O-Ring that is on fill neck going into gas tank. BTW how is your gas cap?

I had a simular problem with my 61 T-bird. It came down to being 2 things.
The accelerating pump on the carburetor were leaking gas when used. The gas dripped down on the hot intake where it vapourized and causing the smell.
The front cowel drain hoses were all dried up and let the engine smells easially in to the passenger compartment.
