Calculating Fuel Line Size
To calculate the correct fuel line size, you can use the following formula:
Fuel Line Size (inches) = (Fuel Flow Rate (gpm) x 0.025) / (Fuel Pressure (psi) x 0.006)
Where:
- Fuel Flow Rate is the maximum fuel flow rate of your engine in gallons per minute (gpm)
- Fuel Pressure is the fuel pressure of your engine in pounds per square inch (psi)
For example, if your engine has a maximum fuel flow rate of 20 gpm and a fuel pressure of 40 psi, the calculated fuel line size would be:
Fuel Line Size (inches) = (20 x 0.025) / (40 x 0.006) = 0.208 inches
Standard Fuel Line Sizes
While the calculated fuel line size may vary depending on the specific application, there are standard fuel line sizes that are commonly used in the automotive industry. These sizes include:
| Fuel Line Size (inches) | Fuel Flow Rate (gpm) |
|---|---|
| 0.25 | Up to 10 |
