I recognize the interesting spelling from other forums and it appears the mechanic is looking for something that does not exist for a Reatta. There is no packaged fuel pump and level gauge sender available. The fuel pump, level gauge sender and inlet filter are all separate pieces. The fuel pump, and filter, are the most commonly replaced items. If the fuel level does not work correctly, Dave has found a substitute from another GM model that works, but indicates empty with a little more fuel left than the original. The exact Reatta sender model has not been available for many years.
