Where is the part number on a fuel pump?
The part number on a fuel pump is typically located on the side or top of the pump housing. This number is important for identifying the specific make and model of the fuel pump, which is crucial when ordering a replacement part. In this article, we'll provide a detailed guide on where to find the part number on a fuel pump.
Locating the Part Number
The part number on a fuel pump is usually a combination of letters and numbers, and it can be found in one of the following locations:
- On the side of the fuel pump housing
- On the top of the fuel pump housing
- On a label or sticker attached to the fuel pump
The part number may be printed directly on the pump or on a label that is affixed to the pump. It's important to carefully inspect the entire surface of the fuel pump to ensure you locate the part number.
Identifying the Part Number
Once you've located the part number, you'll need to identify the specific make and model of the fuel pump. This information is crucial when ordering a replacement part, as fuel pumps can vary significantly in their design and specifications. The part number will typically include a combination of letters and numbers that indicate the pump's manufacturer, model, and other identifying details.
For example, a part number like "FP-123A" might indicate that the fuel pump is made by a specific manufacturer and is a specific model within their product line. By referencing this part number, you can ensure that you order the correct replacement fuel pump for your vehicle.
Tips for Finding the Part Number
- Carefully inspect the entire surface of the fuel pump, including the sides and top, to locate the part number.
- If the part number is not visible on the pump itself, check for a label or sticker that may be attached to the pump.
- If you're still unable to locate the part number, consult your vehicle's owner's manual or contact the manufacturer for assistance.
By following these steps, you can quickly and easily locate the part number on your fuel pump, which will help ensure that you order the correct replacement part for your vehicle.
What are the numbers on a fuel pump?
"Fuel pump numbers" can refer to octane ratings at a gas station (like 87, 89, or 91) or part numbers for replacement fuel pumps. Gas pump octane numbers indicate a fuel's resistance to engine knocking, with higher numbers meaning higher resistance. Part numbers are used to identify specific models of mechanical, electrical, or module-type fuel pumps for repair and replacement purposes.
At the gas station
- Octane rating: The numbers on a gas pump (e.g., 87, 89, 91) refer to the octane rating, which measures a fuel's resistance to "knocking" or premature detonation in an engine.
- Typical grades: In the United States, the three main grades are regular (usually 87 octane), midgrade (89-90 octane), and premium (91-94 octane).
- Higher is not always better: You should use the octane rating recommended by your vehicle's manufacturer. Using a higher octane than needed will not provide benefits in most standard engines.
For auto parts
- Part numbers: These are unique identifiers used to order replacement fuel pumps.
- Examples:
- Mechanical fuel pumps: Part numbers may start with "MF" (e.g., MF0076).
- Electrical fuel pumps: Part numbers may start with "FD" or "FE" (e.g., FD0031, FE0441).
- Fuel pump module assemblies: Part numbers may start with "FG" (e.g., FG0111).
- Finding the number: If you need a part number, you can look it up in a manufacturer's catalog or use the vehicle identification number (VIN) to find the correct part.
Where to find part number on fuel pump?
Part numbers, also sometimes referred to as model numbers, can be found on your pump's tag. A pump tag is a small rectangular plate that displays all the basic information about your pump.
Where is the serial number on a fuel pump?
Serial numbers are indicated on the pump nameplate as well as stamped on the pump casing.
How do I find out what fuel pump I need?
To find the right fuel pump, you need to know your engine's horsepower, fuel pressure requirements, and fuel type, as these factors determine the necessary flow rate and pressure the pump must provide. Additionally, you must decide between an in-tank or in-line pump and consider factors like voltage, filtration, and whether a return-style fuel system is appropriate for your vehicle.
Key factors to consider
- Horsepower: Higher horsepower engines require more fuel, so a higher flow rate (measured in gallons per hour or liters per hour) is needed.
- Fuel Pressure:
- Carbureted engines: Typically need lower pressure, between 4 and 9 psi.
- Fuel-injected (EFI) engines: Require much higher pressure, often between 40 and 60 psi.
- Forced induction engines (turbocharged or supercharged): Need pressure that increases with boost levels.
- Fuel Type: Some fuels, like E85, require a significantly higher flow rate than gasoline due to lower energy content.
- Voltage: The voltage supplied to the pump affects its flow rate; for example, a pump rated at 60 psi and 13.5 volts will flow more than the same pump at 12 volts.
- System Type:
- Return vs. non-return: A return-style system is generally recommended for EFI as it circulates fuel, which helps cool the pump and eliminates air pockets.
- In-tank vs. in-line: In-tank pumps are cooled by the fuel, while in-line pumps are often easier and less expensive to replace.
How to choose
- Determine your engine's needs: Find your engine's maximum horsepower, its specific fuel pressure requirements, and the fuel type it uses.
- Calculate the required flow rate: Use your horsepower and fuel type to estimate the required flow rate in gallons per hour (gph) or liters per hour (lph). A general rule of thumb is to calculate approximately 0.5 pounds of fuel per hour per horsepower for gasoline, but this can vary.
- Find a pump that meets the requirements: Look for a fuel pump that can provide the necessary flow rate at your required pressure and voltage.
- Consider system requirements: Decide on an in-tank or in-line pump and whether a return-style system is needed for your application.
- Account for other factors: Select a pump with appropriate filtration and fittings, and ensure your electrical system can handle the pump's power draw.
