I have my tank on the CG with a Cline regulator (Iron Bay regulator is the same) and a Saito 100. I chose the regulator because after having dealt with pumps in the past, the Cline was the easiest to set up, nothing to adjust, no flooding, no loading up, no unintentional lean runs, and no midrange issues. The concept is simpler, just a diaphragm that inhibits fuel unless the carb asks for it, and a check valve on the muffler pressure tap to pump up the fuel tank to provide positive pressure to the diaphragm. The only down side to it was placement of the regulator inside the cowl within an inch of the carb, but even that wasnt too bad... although all the fuel lines look a little busy

Pumps work too, I'm sure the perry folks will pipe up soon, there are some bennies to pumps - this is just my humble opinion.
