check the vacum line to the fuel pressure regulator, if its wet, that means the diaphram is ripped, cuzzing poor fuel economy, and a gas smell. this is common on tpi cars.

My car is the same way. real bad odor under hood but no leaks. Im thinking its my regulator as well. I am replacing all the O rings and getting a new regullator body in the next month. hopefully this fixes the 5 gallons to a mile fuel economy I get
