First, you need to determine whether you need a Standard Duty or Commercial Duty/Heavy Duty fuel transfer system. Will you be transferring small amounts of fuel may times, or will you be transferring high volumes of fuel to heavy equipment out in the field? Will you have access to your electrical services to run your pump? Or, will you need a battery-powered pump to refuel out in the field? If you donﾒt have access to a power supply, you need a hand pump. These simple-to-use and economical pumps transfer fluid safely and cleanly. Choose the method of transfer (lever action piston pump, diaphragm pump or rotary action pump) and check the features to make sure it works with the type of fluid you want to transfer. Also consider whether you want a manual or automatic nozzle. An automatic nozzle has an automatic shutoff feature for hands-free refueling. This feature costs more than manual, but may well be worth it in the long run if it frees you up for other tasks.
