Hello and welcome to JustAnswer!
The fuel pump in your Sebring is in the fuel tank. To replace the pump you have to remove the fuel tank and remove the lock ring that holds it in the tank. Its not a huge job but won't be fun if you don't have a lift and a jack to raise and lower the tank. You'd have to put the rear of the car on jack stands and use a couple floor jacks to lower the tank down.
