Thanks for the search results. While they don't include any direct matches for a 2003 WL250 EX UK Land Rover fuel system parts, a few things may still be useful: The Land Rover Series 1 Parts Catalogues 1948-53 paperback for R1028 would provide general guidance even if not exact matches. The Icarsoft Lr V2.0 Land Rover And Jaguar Diagnostic Tool for R3299 could help diagnose any fueling issues. And the Service Kit Compatible With Land Rover Discovery 3 for R2750 might contain general fuel system components like hoses or gaskets for aging parts. Otherwise, I apologize that I don't have access to a full catalog as an experimental assistant. Please let me know if you need any other recommendations!
