I wanted to know how i can stop the smell of gas and exhaust fumes coming inside the my car. I find that when ever i put in gas and fill it more the half a tank i get a strong smell of gas. Anyway to stop this?

Also, when I'm driving my car to work lets say, I totally have smell or exhaust fumes. This really prevents me from driving the car more often. This bothers me every time i take the car. Any help or ideas would be greatly appreciated. I normally have a roof down, but i've noticed this also when the roof is closed. I don't notice much smoke coming in when the roof is closed. I'm wondering if maybe because the engine is directly behind me that it would cause this. Has anyone else experienced this?

HI. Change out all the fuel line and fuel vapor vent hoses. Inspect the fuel tank fill line and tank vent. Inspect the plastic separators for cracks. Check the check valve so that it can 'suck' only. The old hose can get 'leaky' along its entire length.

The factory fuel and emissions hose material tends to dry-rot. Replace w/ modern fuel hose.

Or, if you don't need to pass emissions tests, remove the network of evaporation system hoses and filters all together, cap one of the 2 pipe outlet on top of gas tank and install check valve on short hose to second pipe outlet. Plug manifold, air cleaner and carb as necessary.

Ditto all the previous suggestions. Also, a few other things to check.



Make sure you have some sort of vapor (activated charcoal) canister connected to the fuel tank vent. Even an old one is better than none.
Make sure you have an underside "belly pan" in place. If you don't it significantly changes up the airflow inside the engine compartment.
Make sure that you have the cover plate that goes on the end of the shifter tunnel. The one that covers the hole at the center bottom of the firewall. If you don't have this you can get a lot of fumes sucked into the cabin through the tunnel.

What?! Damn, I gotta go check the fische, I never realized there was supposed to be a cover on the back of that thing, I always thought it was just an (ineffective) fresh air itake for the engine compartment!

Yup. Of course, I'm talking about the upper tunnel where the shifter rod comes through, not the lower tunnel where the A/C lines run.

It has a rubber sealed cover with holes for the shifter shaft, parking brake rod, and the two heater tubes. If you're missing that you are likely pulling some engine compartment air into the cabin.
