Land Rover Part Number: WTB500240 - Fuel Vapour Reservoir Assembly
WTB500240 is a Fuel Vapour Reservoir Assembly fitted to the fuel tank and vapour recovery system on L322 Range Rover V8 petrol engines. The reservoir provides a controlled volume within the evaporative emissions system to manage fuel vapour generated at the tank, moderating vapour flow during normal operation and during vapour recovery cycles. It connects to valves and hoses that route vapour for temporary retention and later processing by the vehicle's emissions control system. The assembly is supplied complete to replace a damaged or degraded tank-side vapour receiver; ensure correct mounting and secure hose and valve connections. Any visible damage or cracking to the reservoir body may allow uncontrolled vapour escape and should prompt replacement. Use the compatibility data below to confirm the correct part for your V.I.N.
Compatibility
- Range Rover (2002-2009) - 4.2 V8 Supercharged
- Range Rover (2010-2012) - 5.0L OHC SGDI Supercharged V8 - AJ133
- Range Rover (2010-2012) - 5.0L OHC SGDI Naturally Aspirated V8 - AJ133 - From VIN AA000001
The WTB500240 fuel vapour reservoir provides a controlled holding volume within the vehicle's evaporative emissions system, capturing and moderating vapour generated at the fuel tank before it is routed for processing. It interfaces with tank-side valves and hoses and supports vapour recovery cycles to prevent uncontrolled venting. If the reservoir is cracked or mounting and hose connections are insecure, vapour can escape and the unit should be replaced.
