My 2005 Pontiac Sunfire is leaking gas under the motor,
Not sure what you mean by "leaking gas from under the motor", but the most likely source of an under the hood gas leak on these cars would be around the O-rings where the fuel injectors connect to the fuel rail. The original O-rings can fail over time as they get older and need to be replaced. I believe this is a common issue with these cars. Even if only one O-ring is currently leaking, its always best to replace all four.
Agree,with 65acre,if it is leaking under hood ,check entire fuel rail,and gas line leading to it,
