So I decided to change my fuel pump today. I thought this will be a 5 minute job. How wrong I was!   In  an attempt to keep the original system I got a Bosch pump off Kieran and took the old one out. Then I sat scratching my head for an hour working out how to remove the pump from the surround and the filter...   Anyway after much pain and help from Kieran here's a picture of it dismantled for anybody who may attempt it.   I just couldn't work out how to dismantle it but essentially   1. Gently removed the bottom outer filter . It pulls off   2. Push the 4 rubber lugs in ( I used a screwdriver and pushed them under the bottom lip of the outer case)   3. Disconnect the top feed pipe clip and the electrical connectors.   4.carefully pull the pump out from the bottom.   5. Remove the pump from the rubber sleeve.   And as Haynes says refitment is the opposite process.   I read a few bits of advice saying it was impossible to remove and you will destroy the housing. If careful it all comes to bits without breaking.   Hope that helps someone
