engine smells like gas

Basically when ever I drive the rodeo the engine smells like gas. I can't find any leaks but the fumes are real strong. Does anyone know where I should be looking. I know its coming from the engine and not the gas tank. Thanks

Pull the vacuum hose off the fuel pressure regulator and see if there's fuel in it. When the diaphragm on the regulator fails it leaks fuel into the vacuum line.

if there is a leak your service engine soon light should be on if so check codes and you may have to have it checked with a smoke machine
