Electric or Mech Fuel Pump? For a carb...

The OP has a Magnum which has neither a mechanical pump "hole" nor an eccentric on the cam to run it. You can buy an adapter for mechanical FP but its a waste when electric pump works better. Best bet is get the pump in the tank where it belongs, unless you like the constant buzzing of a diaphragm type "jiggler" electric pump which will not be alcohol fuel compatible either and made in china.
