Why does my garage always smell like gasoline after I drive E30

[whiteknightfl]

E30 104k miles. AfteR I drive my garage smells like gasoline. Any ideas?

Bad evaporative line, the larger line behind a metal cover in the rear passenger wheel well. It's 13mm inner diameter IIRC, so any 1/2 fuel hose will work since it is under no pressure.

Could also be the fuel pump or fuel sender seals, but you'd smell those in the inside of the car.

Also worth checking your engine bay fuel lines.

104k miles but also 30+ years.

Filling your tank too much? My E39 leaks from an overflow vent somewhere if I fill it all the way.

In my case it was a rusted-through hardline to the charcoal canister.





This diagram may also be helpful. This is for the early-model E30, yours will be different if it's a late model.

Yep. Fuel is coming out somewhere. Just gotta trace the diagram

Find that leak! You won't be the first one to burn up an E30 by not dealing with a fuel leak. Trace the lines from the tank to the engine. Remove the rear seat, then the access cover to the fuel pump and sending unit. Check those hoses. Also, the expansion tank sits behind the filler neck. Remove the rear wheel, remove the splash shield and check all those hoses also.
