Troubleshooting Codes

Curious if anyone has run into this, CEL came on this morning upon start up and gave me codes P0463 and P1494. I do know it is fuel related with the sender producing too much voltage? and fuel leak detection. Question is what steps should I take in troubleshooting the problem?

The first one is the sending unit for the fuel pump and the second code is a bad Leak Detection Pump. It is located under the charcoal canister/solenoid on the driver's fender.
