Some more info:
"The stock pump is a 'demand type'. Here is how it works. Upon start up, the pump cycles on for about 5 seconds, pressurizing the fuel line up to the carbs. Once the line is pressurized, the pump stays in the 'open' position and stops working (ie: the line is pressurized, we need no more fuel). As line pressure drops, the diaphragm in the pump collapses and the points make contact and the cycle repeats. Repeats that is, until the points burn out as in the pics above. Or you get it wet. Or it just decides you are now in a beuatiful natural setting and it doesn't care... it's just going to take a shite and leave your sorry ass right where you are...
The Facet 40105 is a floating piston pump. Here is how IT works. DC current is applied to an electronic circuit that converts the DC to AC, which for those of you in Rio Linda, CA. traslates to 'Alternating Current'. The Alternating Current is applied to a coil thereby creating an alternating magnetic field. Inside of this field is a metal 'shuttle piston' that now slides back and forth. A one way valve in the mechanism makes sure the fuel only goes up to the carbs, which is why there is a directional arrow on the pump housing. The looseness of the shuttle piston in its bore, insures that the pressure will not exceed a set amount. The pump just sits and buzzes fuel up to the carbs. all day long. One moving part, Homer Simpson simple!
Class Dismissed!"
