[quote=LUVMBDiesels;2125558]What car is it? Does it smell inside the car or only under the hood? Does it only smell with the car running or all the time?

Year, model, etc would help.
Without this information I can tell you to check the following.

Rubber fuel lines -- check with the car running as they could have a pinhole.
Idle control valve
Charcoal canister
Fuel injector lines

If the car has a carburetor
Check the base for leaks as well as the float reservoir
Check the intake manifold for leaks.
