TD5 injectors... buy new ones or service the current ones?!!

Hi all,

I just rebuilt my TD5 2001 (D90 NAS) engine, all new parts except injectors due to the exhorbitant cost... (500£ a piece!) I believe they are Lucas Diesel electronic injectors...

Need help finding reasonablly priced injectors or how I can service them or any injector cleaning fluid that I can use to enhance their performance.

Thanks for the help...

they can be had for around the £200 Fuel Injector Td5 98-01 (Blue) MSC000040 Island 4x4 - Specialists in Land Rover and Range Rover Parts and accessories for all models. UK and worldwide mail order.
