Trying to figure out best fuel pump for a multi-port injection system (its a manual mixture control injection system for an aircraft) that requires 20-25 PSI fuel pressure. the LS3 is limited to 1800 RPM by ignition controller. the pump needs to be a quality external (not fuel cell mounted) electric pump. I prefer a GM part, or AC Delco, but Delphi brands first, the aftermarket brands. Any suggestions are appreciated. thanks
