When choosing petrol pumps, there are certain factors you need to consider. First, you should remember that they can vary in terms of sizes, features and shapes. When shopping for one, be sure to get one that perfectly suits your application.
Even though there are many factors to look into before settling on specific petrol pumps, below are some key ones to consider:
- The maximum petrol system pressure
- Horse power
In the article below, you will find useful information on how to choose the right petrol pump. Read on to find out more.
What to Consider When Choosing Petrol Pumps
When selecting a fuel pump, the choice goes beyond the physical size of the pump. It is more important to think about the volume of fuel that can flow through it. You can rate your fuel volume on litres-per-hour or gallons-per-hour. Here are some crucial details to consider when choosing a fuel pump:
The fuel volume highly relies on horsepower rating and the Brake Specific Fuel Consumption (B.S.F.C.). B.S.F.C. is the amount of fuel a vehicle consumes to the unit of power it produces.
As a driver, all you will need to calculate is the average fuel you need by the horsepower rating and B.S.F.C. You may also realise that the amount of fuel used and the B.S.F.C. will differ depending on the efficiency of the vehicle.
If you are unsure of your car’s horse power, it is best to consult with a mechanic before making a purchase. This is because if you make the wrong calculations on your vehicle’s horse power, you may buy the wrong pump and severely damage its engine.
Engine Fuel Efficiency
To determine whether your engine is efficient, you will have to calculate the amount of fuel it needs to produce 1 HP in one hour. The majority of modern engines fall under the following categories:
- Engine Type: Normal Aspirated Engine Industry B.S.F.C. Standards 45-.5
- Engine Type: Super Charged Engines, Industry B.S.F.C. Standards 55-.60
- Engine Type: Turbo charged Engines, Industry B.S.F.C. Standards 6-.65
As a driver, you can use these figures as guidelines, but the best way of getting the exact B.S.F.C. figure is by carrying out an engine dyno test.
When choosing a fuel pump, it’s important to go for one that works within the engine’s voltage output. When you increase the voltage of a pump, it will either make or break the pump’s performance – even more so if it is under high pressure. For instance, if you use a fuel pump that pumps 12 volts to a car with an engine output of 13.5 volts, it will automatically increase the volume of the fuel that it pumps, which may cause serious damage to the pump.
With the above information, it will become easier to select a fuel pump when you need one. You will know what to look for in fuel pressure, voltage supply and engine fuel efficiency. That way, it will be easier to select the best petrol pumps for your application.
