1. What is GPH to LPH Conversion?

The GPH to LPH converter calculates fuel pump flow rate from gallons per hour (GPH) to liters per hour (LPH). This conversion is essential for comparing fuel pump specifications and ensuring proper fuel delivery in various applications.

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Where:

• \( LPH \) — Flow rate in liters per hour
• \( GPH \) — Flow rate in gallons per hour
• \( 3.785 \) — Conversion factor (1 gallon = 3.785 liters)

3. Importance of Fuel Pump Flow Rate

Details: Proper fuel pump flow rate is critical for engine performance. Too little flow can cause lean conditions and engine damage, while excessive flow wastes energy and may overwhelm the fuel pressure regulator.

4. Using the Calculator

Tips: Enter the fuel pump flow rate in gallons per hour (GPH). The value must be greater than 0. The calculator will instantly show the equivalent flow rate in liters per hour (LPH).

5. Frequently Asked Questions (FAQ)

Q1: Why convert between GPH and LPH?
A: Different manufacturers use different units, and some applications require metric measurements. Conversion allows for accurate comparison and specification matching.

Q2: What's a typical fuel pump flow rate?
A: Passenger vehicles typically use pumps with 30-80 GPH (114-303 LPH), while high-performance applications may require 100+ GPH (379+ LPH).

Q3: How do I measure actual fuel pump flow?
A: Measure how much fuel the pump delivers in one minute at operating pressure, then multiply by 60 for GPH or use this calculator to convert to LPH.

Q4: Does fuel type affect the conversion?
A: No, the volume conversion is the same regardless of fuel type (gasoline, diesel, ethanol, etc.).

Q5: When should I upgrade my fuel pump?
A: When adding forced induction, increasing horsepower significantly, or if experiencing fuel starvation at high RPM.
