R1200GS 04MY 55Plate 2006 32K miles - On my last ride to France last year I noticed these leak marks on left side of bike.


I got home cleaned it off and put the bike away for the winter. Off to Portugal in May so yesterday I thought I'd better get her out give her a run and find out if the leak was still there. Within a mile or so I could see drips coming off of the lower side panel below the tank. Further investigation revealed the dreaded fuel pump flange had hair line cracks in the boss that the QR line connects to from the high pressure side of the pump. And this is with my bike having had the BMW recall to have the metal collar fitted to the flange! I couldn't be asked to take this up with BMW so I contacted MotoWorks and have a used flange but good flange being sent to me.
Question for the learned of this forum - Would you use any jointing compound or PTFE tape around the QR union that screws into the flange or just assemble 'o natural'? And I assume that you shouldn't do the QR up too tight as it is has a tapered thread that effectively puts pressure on the moulded flange boss and cracks it. I've attached some pics that should help to explain.
Thanks for any advice.
