Lift Pump
The Lift Pump is a low pressure pump designed to lift the fuel from the fuel
tank to the swirl pot.
The Lift Pump must be capable of flowing enough fuel for full power
operation.
Swirl Pot
The swirl pot (Header Tank) maintains a reserve of fuel to avoid fuel
starvation to the engine during cornering and acceleration. Fuel starvation
can also cause damage to the pressure pump as it relies on the fuel for
cooling, lubrication and speed limiting.
The swirl pot also forms a header tank for the pressure pump since the
pressure pump is not capable of lifting the fuel from the tank if the tank is
lower than the pump. Place the swirl pot at the same level, or higher than the
pressure pump.
Pressure Pump
The Pressure Pump is a high pressure pump that must be capable of
delivering the required amount of fuel at the correct pressure at full power.
