I think I’ve found and corrected my noisy fuel pump issue.
With the engine running I felt and tugged on the fuel lines with no change in the pump noise until I got to engine compartment. The AN 6, pressure fuel hose attached between the engine and the steel fuel line at the frame rail could be moved and the noise would stop. The line was attached in a horizontal position. I situated the hose in a more vertical position and the noise and pressure line pulsation are mostly gone. Much quieter, cant hear it driving and only faintly with the hood open.
Attached a picture of the hose in its new position.
