thanks gents ,the reason I ask is that the car is pretty old (EK Holden ) and the existing tank is only 150 mm deep , I have been told I need a surge tank , high and low pressure pumps , regulator and inline filters etc , just though it might be easier to take the old tank out and replace it with one that goes with the 1uz engine . I would like to keep the old tank though if it makes sense to go with the external pumps , it would look more original , so does anyone have a simple plan.
