Don't know how you got 7 litres in. Normal refill is less than 5. I take you did it on level ground.
Oh I thought it was too low as RAVE says it's 9.7? Some of that 7 could well have been what was in my upgraded (rather large) delivery pipe.
Most level I have access to ie the road - spirit level indicated it was fine
Just driven her, and the good news is she's running fine so I haven't broken anything internally
The bad news is that it's weeping around the sheered bolt :'( Any suggestions for this.. Can I just drill through the screw?
