What engine? What kind of Fuel system, CPI, SFI, MFPI, Throttle body, etc. Sounds like a leaking fuel injection line inside the manifold, very common problem on 4.3L CPI, and MFPI engines. Could also be a leaking Fuel pressure regulator on similar engines with it inside the intake manifold.
Has your mileage gone down recently?
