Quicksilver 25L petrol tank....
Now surplus to requirement , as per pic.
The feed pipe/connection has a crack in it (where I have slipped a bit of paper in to show) so I would not use this actually run an engine , but I have been using to top off the tank on the boat with a simple syphon tube down to tank. Or to carry on deck.
£10 - really need to be picked up, or can drop off Southampton/Portsmouth way in 2 weeks.
