Larger suction pipe to pump - better?
All inside tubes, inlets on the pump, and suction tube from fresh tank are 1/2". 3GPM pump, 40 PSI on the push side, self-priming up to 10ft (I think). Now, imagine fresh tank 6ft away, sitting on...

Better or worse what? Pressure? Flow rate? The answer to both though, is "No." The limitation is the inlet bore on the pump as well as the internal pump "plumbing" where the water passes through the diaphragm ports and check valves. The only practical cure for that is a pump with a higher pressure/flow rate capacity.
