I have strong gas smell in my dodge 2000 interpid but i see no leaks anyway. also running out of gas faster.

Thanks for choosing FixYa and welcome. You may want to try a fuel cleaner and changing the fuel filter first if you haven't already. Check for any codes that may have came up if the check engine light is on. Check all your fuel lines and gas tank again. You may have a bad fuel injector so check them for sure. If one is leaking, fuel can be smelled. A simple tune up can help your gas mileage, as well as the cleaner. Check around the fuel filter for loose hoses. If you can access the fuel pump from your back seat, check in that area also. Check the engine block for leaks. Remember, if it is leaking there, the gas will evaporate before you notice leaking spots. Check all your lines behind the engine block and at the firewall. Are your rpm's jumping any? High idle? The throttle may need adjusted. You may be getting rich fuel as well. Check your catylactic convertor. There may be a leak around the fuel pump so that is an option also. If it is not in the back seat, you will have to pull the tank to check it though.
