82 xj6 series 3

So I decided to drain the right tank which is the tank I haven't been driving on. When I pulled out the plug it was covered in black sludge/grime/dirt. The filter on the plug to was falling apart. Just goes to show these tanks being this old def need a cleaning for anyone who thinks this is a issue or is having fuel related problems. Wish I could of recorded a video for you guy to see
