Proflow single or dual pump fuel surge tank systems prevent starvation due to fuel sloshing or limited tank baffling. Proflow fuel surge tank systems maintain a small amount of fuel to operate their own internal fuel pump that can supply high fuel flow rates, while only needing a relatively low fuel flow rate from the main fuel pump. A return line is required to return excess fuel back to the vehicle's fuel tank. Every Proflow surge tank features a high-quality billet aluminium construction and long-lasting finish. Available in polished or black finish.
