I found a good thread about removing the tank for s-types but not a 2007 XKR. One of the nipples broke off, I read the manual I have and now I have all the hoses disconnected. It seems I need to slide the tank toward the engine but the tower strut is in the way. I saw in the manual how to remove the tank mounting bracket, it has three bolts but can only feel two.
So do I just force the tank out, or do I need to loosen the tank mounting bracket.

Thank you!!

 

When I replaced the expansion tank on my 2007 XK, I loosened the hardware securing the tower strut, to provide a bit more space to extract the tank.

 

Yank it out. With it pushed up against the bar.
