GUYS, I am sure that when i changed the fuel filter it had plenty of natural pressure (hydrostatic head pressure I guess) but thought I would check what people thought as cleaning the tank might be a pain !
thanks again Jeff. Jeff, Yep I was just going to say what Kris said :) Andrew > Jeff, > Has it always had this problem?
