after driving to work or home or where ever I can smell fuel in engine compartment. driverside front. I have looked and have been unable to find a fuel leak.Am I missing something?.

99 suburban 6.5 turbo 4x4 192,000 miles

 

Possibly a return hose on an injector is cracked, or the return line is leaking on the injection pump.

 

you sure its diesel fuel or diesel smoke. i bet you got an exhaust leak just like me. if im sitting at a stoplight and there is just enough wind the diesel smell fills the cab until i satrt driving. its not too bad just a little hint of it
