Apparently the Piston is pushed positively in one direction against Spring Pressure but on the way back the Spring Pushes the Piston. This means that that if the Outlet of the Fuel Supply/Lift Pump was Plugged the Piston being pushed back under Spring Tension would not move until what is blocking the Outlet is removed.
I see, so the pressure can never rise higher than what the spring tension can produce? That makes a lot of sense. Otherwise one clogged injector would likely destroy the pump.
