What seemed to work was a small Facet Posiflow fitted on the inner wing, pressure is about 2psi and no sign of either starvation or overfilling.

Some thought has to be given to the fuel pump action when deciding where to place pump. Pumps can give short suck long blow (place near tank) or vice versa (place near carb). I remember spending time on a diesel heater installation on a yacht. The run from tank to heater in stern of boat was over 20 feet down narrow bore pipe, moving pump from close to tank to near heater solved the fuel starvation issue.
