Adding fuel might affect the reliability of the fuel system, and certainly would affect the operational characteristics. Therefore I think this isnít a minor change and requires FAA approval and an airworthiness review. Is this correct?
Make an appointment with your local FSDO to get the airworthiness certificate and operating limitations re-issued. Your new oplims will require that you notify the FSDO of your intention to put the airplane into phase 1 after a major change and get their approval of your proposed test flight area. They won't need to re-inspect the airplane. It may be possible for a DAR to issue the certificate and oplims. It's worth checking with a local DAR.
