good point

but where are those 180 original coming from

is it just a fault then.
I don't know it. I didn't go and measure the two tanks out...
3 and 8 seems pretty close, so might be an idea to change it to 130 then. At least what I know is, the German [img]/threads/images/Graemlins/Flag_Germany.gif[/img] and the Swiss [img]/threads/images/Graemlins/Flag_Switzerland.gif[/img] manufacturer are working close together (very close) [img]/threads/images/Graemlins/icon07.gif[/img]
