Jet Pump

WARNING: This page is about a different car, the 2010 Jaguar XF and 2009 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The fuel system incorporates two jet pumps. One jet pump is integrated into the fuel pump and draws fuel from the right-hand (RH) side of the fuel tank. The other jet pump is located in the left-hand (LH) side of the fuel tank. The jet pumps operate on a venturi effect created by the fuel at pump output pressure passing through the jet pump. This draws additional fuel from the left-hand (LH) side of the tank through ports in the jet pump body, delivering additional fuel to the swirl pot.
