Fuel Tank and Lines: Overview

WARNING: This page is about a different car, the 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The fuel delivery system incorporates a Low Pressure (LP) and High Pressure (HP) circuits to provide the engine with sufficient fuel for all operating conditions.

The LP fuel system features the following components:

Molded plastic saddle type fuel tank
Fuel pump module (with integral in-tank pump)
Fuel Pump Driver Module (FPDM).

The fuel system uses an electronically controlled returnless fuel system. This will allow the LP fuel pump to deliver fuel to the HP fuel pump, dependent on engine demand.

The in-tank LP fuel pump also supplies fuel to the 2 jet pumps on either side of the fuel tank. Thereby the LP fuel pump provides sufficient fuel in the swirl pot.

The HP fuel system is described in 'Fuel Charging and Controls' portion. For additional information, Refer to: FUEL CHARGING AND CONTROLS .

The emissions system is described in 'Engine Emission Control' portion. For additional information, Refer to: ENGINE EMISSION CONTROL .
