Not sure on the disco but many modern petrol cars dont have a filter just a gauze in the tank, some of the mercs used to have a filter which was also the fuel pressure regulator

FUEL DELIVERY – V8
DESCRIPTION AND OPERATION
V8 Fuel Delivery System.
Fuel Delivery System Components
The Land Rover V8 fuel delivery system comprises the following main components:
l Saddle type fuel tank
l Fuel injectors
l Non return fuel rail
l Fuel pump
l On board refuelling vapour recovery system (NAS only)
l Tank leakage detection system (NAS only).
Fuel Tank
The fuel tank is constructed from moulded plastic and is mounted under the rear seat just forward of the rear axle.
The fuel tank has a 100 Litre capacity and activates a low fuel warning lamp in the instrument pack when there is 12
litres in the tank. The tank is of the saddle tank design with a siphon jet pump in the left side to transfer fuel to the right
side where the fuel pump is mounted. The fuel is delivered along pipes that run along the underside of the vehicle to
a fuel rail mounted on the engine.
Fuel Filter
The fuel filter/pressure regulator is mounted in on the lower right hand side of the tank. The charcoal canister is
mounted at the front of the tank on the right hand side. The components are covered by a plastic under tray to protect
them when driving off-road. The undertray has an inspection cover to enable access to the charcoal canister and the
fuel filter.
Fuel Pump
The fuel pump comprises a pump, sender unit, pot and ventrui. The unit has an integral filter inside the pot. The pump
unit operates at 3.5 bar for 170–205 l/hr (the V8 has a maximum operating requirement of 90 l/hr).
The pump is controlled by the ECM via the fuel pump relay.It can when others can't,
It will when others won't,
It goes where others don't.

From the workshop manual, no mention of replacement and if it was the case it would involve the removal of the fuel tank.:

Fuel Pump Module
The fuel pump module is attached to the carrier and is located at the bottom of the swirl pot. The pump module flange has three electrical connectors; one for the fuel pump motor and one for each of the fuel level sensors. All are connected to the external electrical connector via the connectors on the underside of the fuel pump module flange.
The pump module has a rated flow of 122 litres/hour (32.2 US gallons/hour) at a voltage of 12.3V and an output pressure of 4.5 bar (65.2 lbf/in2).
The fuel pump is energised by the fuel pump relay which is located in the battery junction box. The relay is controlled by the engine control module and energises the relay at all times when the ignition switch is in ignition position II.
A pump inlet filter is attached to the pump inlet port at the bottom of the pump. The filter has a 'winged' section which is located vertically at the side of the pump to ensure that a portion of the filter is off the base of the swirl pot, to prevent premature blocking of the filter. The filter has a 31 micron fine mesh filter with a surface area of 70 cm2 (10.8 in2).
A second fine mesh filter is located around the top of the fuel pump. This provides additional filtration to the fuel before it is passed into the manifold and onto the fuel rail. The filter has an electrical connection which is attached to ground. The ground is required to dissipate electrostatic charges that can build up on the fine filter. The fuel filter outlet also incorporates a non-return valve which prevents fuel returning to the pump when the engine is not running. This ensures that system pressure is maintained in the fuel feed line to the fuel rail when the engine is not running.

You wont see it, its part of the fuel pump which is inside the petrol tank, the only way is to remove the tank, I don't believe its meant to be serviced.==================================
