Fuel Injection Pump
WARNING: This page is about a different car, the 2012 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
The fuel injection pump is a single piston and a delivery-on-demand design. The pump is driven from an eccentric on the LH intake camshaft. It can raise fuel pressure from 448 kPa (65 psi) to anywhere between 1, 516 and 14, 823 kPa (220 and 2, 150 psi). The fuel is then supplied to the fuel injectors for distribution into the cylinders.
