Hercules Automobiles Int’l (P) Ltd offers reliable fuel pumps that can work on even the most extreme environmental conditions. As a logical complement to the pump program, the company has developed complete in-tank modules around the fuel pumps that make the pump a complete fuel supply system with numerous additional functions. These functions include the delivery of fuel to the evacuation location (reservoir for curve driving ), the tank filling level detector, the improved fitting of the pump inside the tank as well as the safe and absolutely tight closing of the tank installation opening. The basis of fuel supply is a two-stage fuel pump whose first pump stage fills the reservoir, from which the second pump stage (pressure stage) takes the fuel. With this concept, fuel supply is guaranteed even under extreme driving and environmental conditions in an ideal way.
