Fleet Refueling Depot: How to Choose and Size a Fuel Dispenser System

Oct 12,2026

Quick Answer:

It’s economically viable to set up a private fuel station in order to reduce fuel costs and time by minimizing visits to commercial fuel stations, especially for all those who require fuel on a daily basis. It’s important to consider that the kind of system to be installed will depend on many factors such as peak demand, kinds of vehicles, fuel storage, and control. Aocheng Group manufactures fuel handling equipment and management systems that suit these factors.

Is On-Site Refueling Cheaper Than Using Public Gas Stations?

On-site refueling will become more cost-effective when the volume of the fuel that is consumed by the fleet is sufficient enough to cover the costs associated with the installation of tanks, pumps, dispensers, and other equipment. Buying bulk volumes of fuel will lower the price per liter, and on-site refueling will allow saving time for visiting the gas stations.

However, the cost savings will not be limited to the price of the fuel. The drivers will not have to go to the public gas stations, wait in line, and pay there. Moreover, the consumption of fuel by vehicles, drivers, departments, and specific tasks will be easier to monitor.

How to Estimate the Return on Investment

There must be a consideration of the savings in terms of the cost of fuel, labor time, losses in fuel, and operating costs.

Net savings per year = fuel cost savings + labor cost savings + loss of fuel savings – operating and maintenance costs.

For example:

A fleet that uses 200,000 liters of fuel per year and saves PHP 3-5 per liter due to bulk purchases would have an estimated savings of PHP 600,000-1,000,000 per year without considering labor and loss savings.

Note: These are purely hypothetical calculations and do not represent guaranteed savings. The real savings would be determined through the prices, annual usage, installation cost, and frequency of use.

The depot is more feasible when there are established routes for the vehicles with returns to the same location. Fleets that consume less fuel or scattered fleets can make do with public filling stations.

How Many Nozzles and What Flow Rate Does a Fleet Need?

The dispenser selection should be made based on peak demand rather than monthly fueling alone. We want to serve the needed number of cars without having queues or excess capacity.

Match Flow Rate to Vehicle Type

The following ranges provide a starting point for fuel dispenser sizing:

Fleet typeSuggested flow rate
Cars, vans, and light vehicles40-60 L/min
Mixed fleet of vans and light trucks70-90 L/min
Trucks, buses, and heavy equipment100-150+ L/min

The rate of requirement depends upon the following factors:

1. Size of tank in the vehicle

2. Fuel inlet configuration

3. Flow of the pump

4. Diameter of hose

5. Capacity of nozzle

Note: The rate of flow of the dispenser should be compatible with the rate of flow of the pump.

Calculate the Number of Active Refueling Lanes

One active lane needs to be provided for each vehicle that is expected to refuel simultaneously. Two nozzles will be adequate for a small yard, while four nozzles will enable larger fleets to handle the demand at the beginning or the end of their shifts.

For example:

Suppose there are eight trucks that require 150 liters of fuel within a one-hour morning period. The total requirement is 1,200 liters. A single lane with a rate of 100 L/min will have the potential of 6,000 liters per hour.

However, the practical potential would be lower when the positioning of the vehicles, authorization, handling the hose, and filling up the tank are considered.

Two lanes would be enough for the above scenario, even though the final decision should be based on the actual time and demand. A test or operation schedule could be conducted to prevent queuing and unnecessary cost.

How Should the Dispenser, Tank, and Fuel Management System Work Together?

The optimal fleet depot needs a systematic approach to storage, dispensing, and transactions. Choosing them individually without making sure that they work well together may lead to inefficiency, incorrect data, and wasted time.

Storage Tank Capacity

Normally, one begins with calculating the storage volume required for a week or two of average fuel consumption. The total volume will depend on the frequency of delivery, lead time, available room, and required ullage – space for fuel expansion.

It should be noted that the tank should meet all regulations and requirements in terms of environmental protection and safety. It all depends on the characteristics of the site.

Pump and Dispenser Selection

The pump should supply the flow required by the fleet, whereas the dispenser, meter, hose, filter, and nozzle should sustain the flow rate and the fuel type required. Accuracy of the meters is crucial since dispensing records will be used for costing purposes and stocktaking.

When installing fleet fuel dispensing systems, it is essential to consider the overall capacity rating of the systems as opposed to one capacity flow rate alone. It is also necessary to ensure that all electrical and fire regulations are observed.

Fuel Management and Back-Office Software

A fuel management system records who dispensed fuel, which vehicle received it, when the transaction occurred, and how much was delivered. Depending on the setup, the system can also record odometer readings or engine hours.

Back-office software can combine transaction records with tank levels and fuel deliveries. This helps managers compare fuel consumption across vehicles, identify unusual activity, and allocate costs to the right department or job.

An automated fuel dispenser can support this process by requiring driver or vehicle identification before dispensing. However, compatibility depends on the dispenser’s authorization interface, meter output, communication protocol, and the management software. These details should be confirmed before purchase.

How Can a Depot Control Access and Prevent Fuel Theft?

Simply having a lock on the tank is not sufficient to manage fuel loss. Proper security at the depot involves controlling access, monitoring transactions, protecting the fuel, and periodic auditing of inventory.

Limit Access for Dispensing of Fuel

Access can be controlled by using PINs, fleet cards, key fobs, or automatic vehicle identification. Access should be restricted only to authorized drivers and vehicles. Limits on the amount of fuel dispensed can also be set per transaction, per day, or per vehicle.

Monitor Tank Levels and Reconcile Inventory

Tank level monitoring can reveal any variation in fuel stocks and signal unusual stock losses. Managers should match the starting stock, delivery of the fuel, dispensation records, and ending stock. Any discrepancy should be investigated immediately as it could suggest leakage, inaccurate measuring, data entry error, or theft.

Physical security is yet another area that needs attention. Access control, locking gates and fuel tank filling stations, sufficient lighting, and surveillance systems would limit the chances of any break-in.

A fuel management system is most useful when its records are reviewed regularly. Installing the technology without checking exceptions or reconciling inventory limits its value.
