The hoses above the tanks include the fuel pick up for the fuel pump. If it is now10 years old it is probably not a barrier hose (which is resistant to the ethanol in the gasoline). It could have cracks that don’t leak gasoline but could allow the fuel pump to suck in air through the cracks. This can give you the power loss problems you have alluded to.

You should replace all of those hoses with barrier hose or you can put in metal lines instead of the rubber ones.
