2008 SEAT Sport UK, Technical Manual – New Leon Cupra v3 (Autosport International)

Fuel Delivery System (5.7.8)

The fuel delivery systems including the tank internals must remain as those supplied by SEAT Sport UK.

The car is fitted with a double-sided fuel tank with two lift pumps. It is not recommended to run with less

then 5 litres remaining in the tank. The system is assembled as shown in diagram 27.

The fuel pressure can be monitored on the data logger. The low-pressure system must run above 2bar and

up to 6.5bar depending on engine load. The lift pumps located inside the fuel tank are operated via a

pulsed current control module, controlled by the engine control unit.

Fitted in the engine bay is a homologated 'Dry break connector' for draining and sampling fuel. To empty

the fuel tank there is a pump out control switch available from SEAT Sport UK, Part No. U4PL 971 001.

Caution! Do not run the lift pumps dry, as this will result in damage.
