Almost all of that heat is Fuel Pump concentrated at The purpose of highest resistance, and in a brush-sort motor, it’s where the carbon brushes touch the rotating copper contacts (commutator bars).
As the lever forces the diaphragm downward, a suction power is established that pulls fuel inside the pump by a Test valve together the fuel pipeline.
