Filling the tank
It is necessary to decide what type of delivery truck the fuel-oil supplier will be using during the design process. Fuel-oil trucks are either a type of gravity or a type of pump (i.e., equipped with an integrated fill pump).
Both types of trucks are capable of handling USTs and ASTs found at elevations below the vehicle. Pump trucks are suitable at higher altitudes for filling ASTs. Gravity trucks are great for filling out USTs. However, a gravity style truck alone won’t operate when the fuel storage tank is at a higher level than the vehicle. A choice for these applications is a remote filling system with an integrated fuel transfer pump that allows gravity trucks to fill ASTs at higher elevations. Remote fill systems are fitted with gages and sensors to assist and alert the operator during the process of delivery.
