Actually it has a hollow iron coated nylon/teflon plunger with a one way valve in one end. It slides back and forth in a sealed unit powered by electromagnets hence the clacking sound. There are one way spring loaded ball valves at the inlet and outlet. Bloody simple but susceptible to dirt I think. They are easy to disassemble but the little springs have a mind of their own and jump all over your workshop. I don't why a Facet would be any better than any other pressure pump in preventing vapour lock.
