Brian,
Petrol isnt to easy to come by in NE Marinas. To the best of my knowledge, Royal Quays (River Tyne) has a pump and then it's down to Hull marina before you get another. Quite a few marinas have petrol stations really near by though.
I guess Royal Quays is a bit close to Amble and Hull a bit far to get to.
I'm often about between Hartlepool and Whitby so PM me if you need some help moving the petrol about.
Ed
