Morning, Fantastic Stef. Thanks!
Funny, I was going to try and work out what else that nozzle could have been for, as it was on my mind that it really wasn't the box oil that came out.
I will have to look harder for that black hex head that is the fill and level point other members have mentioned in g/b topic.
Why do the answers to my questions come on the morning its raining that cold wintery/icy rain, not wishing to sound ungrateful buddy . Just have to drink plenty of tea today I geuss n light a fire somewhere nearby (or manup ). Hopefully you have helped me in the nick of time and overted us having another seased box .
Thanks again Stef, have a nice warm day
