And the pump is in good shape. That image near the bottom of the pump rotor with three of the five rollers, and the housing it spins in -- that pump shoves through sixty-plus liters per hour of gasoline at high pressure by pulling it into the gap on one side of the rotor as it increases to what must be easily a millimeter or better, and rolling that droplet of gasoline around to the other side where it gets squeezed out the side when the gap closes. Five times per revolution, and with the dimensions you could figure out how fast it has to be turning. Pretty fast. Yours, d |
