I pulled the fuel filter and turned the key to the "ON" position and heard the pump run but no fuel came from the lines (left tank only, I tried right but no pump noise). I have not worked on the dual tank setup at all so can anyone explain this to me please?

One fuel pump in each tank... 2 fuel pumps.

Not in stock dress. The selector valve switches the feed and return lines from Left or Right tanks to the engine compartment fuel feed and returns. The fuel filter is after the valve.

No.
It sounds like the selector has moved to the RIGHT tank then hung... And... the RIGHT tank has a fuel pump issue.
