The 5.5L Staged Surge tank is designed so you have the ability to turn 1, 2 or 3 pumps on in stages. Running all 3 pumps at the same time is not necessary for light throttle driving or cruising or idling a car, doing so will add excess heat to the fuel system. By running a single pump for 90% of the driving until you need more fuel flow you can lessen the heat and load on the fuel system. Our 5.5SST is designed with 2 stages in mind. Stage 1 for your primary pump to carry the load of idle, cruising and daily driving, and Stage 2 for up to two additional pumps to carry the load of extreme boost or race applications.
