If you think that your lift pump is not capable of maintaining a full surge tank either your tank is to small or your lift pump is to small. The advertised flow ratings for most pumps is in US gallons (3.75 litres) per hour at what ever restriction required to achieve a rated pressure, when you remove the restriction and the pump is in free flow the volume is greatly increased, Make sure that the surge tank has the same size return as supply.

Can you get non-return valves as I would want to plumb the high pressure return and the "low pressure" Surge Tank overflow back to a single outlet in the Fuel Tank?
