Put bad gas in my car. Where is the fuel pump relay and fuel filter

The fuel filter is integral to the fuel pump itself. This means you'd replace the pump, essentially, to replace the filter. In other words - not a maintenance service to be performed. "Bad gas" - are you certain you had bad gas? Highly unusual to happen these days. Fuel pump relay is in an under hood relay / fuse box.
