I finally put enough miles on this new-to-me 1970 914-4 to refuel it. Since then I've noticed a strong gasoline smell after hard acceleration. I've tried fiddling with the gas cap to get it to seal better, but I'm also wondering if it's the correct one for the car. Many years ago I had a 1975 and 1973 and don't remember the gas cap looking like this.

The 75 cap would have been different. The 73 cap would have been like this--but someone painted this one.
I believe there is a seal on the underside of the cap; it can fail after a few decades. Double-check your charcoal canister lines. If they are unplugged they can lead to a gas smell. I think there is a gasket between the fuel filler neck assembly and the tank. A leak there might possibly give you a fuel smell too. The tank often rusts where it rests on the shell of the car--there are felt pads that can trap moisture and lead to pinholes. --DD |

Also make sure the large clear overflow line exits out from under the car. |

Is the large clear overflow line supposed to attach here? There should be a small cloth cover rubber line from the nipple on the filler going to the charcoal filter on top of the fuel tank. |
