The Basics:
Optimized Performance:
Fuel pumps are designed to ensure the efficient delivery of fuel to the engine, enabling optimal performance and power production. Upgrading fuel pumps often involves replacing stock units with high-performance versions that can handle increased fuel flow and pressure. The need for a fuel pump upgrade is dependent on the platform, goals, and fuel used. Common examples of upgraded fuel pump components include high-flow fuel pumps, fuel pressure regulators, and fuel injectors.

How it Works:
Types of Fuel Pumps:
External Fuel Pumps: Mounted outside the fuel tank, these pumps pull fuel from the tank and push it to the engine. They are often used in high-performance and racing applications where easy access and maintenance are crucial. External fuel pumps are also used in situations where the fuel tank design does not accommodate an in-tank pump.
High-Pressure Fuel Pumps (HPFP): These pumps are essential for direct fuel injection systems, delivering fuel at very high pressures to ensure efficient combustion and power output. High-pressure fuel pumps are crucial for systems like Direct Injection, where precise fuel delivery at high pressures is necessary for optimal engine performance and efficiency.
Lift Pumps: These pumps are used to transfer fuel from the fuel tank to the high-pressure fuel pump. They are essential for maintaining the proper fuel flow and pressure required for the high-pressure pump to function effectively.
In-Tank Fuel Pumps: Located inside the fuel tank, these pumps push fuel from the tank to the engine. They are commonly used in modern vehicles due to their efficiency and ability to reduce the risk of vapor lock. In-tank fuel pumps are often part of a fuel module that includes the fuel level sensor and other components, making them integral to the vehicle's fuel delivery system.
Low-Pressure Fuel Pumps (LPFP): These pumps deliver fuel at lower pressures. They are simpler and less expensive than high-pressure pumps.
Explorer-Specific Recommendations:
General recommendations for this platform are as follows:
HPFP:
Choose one that provides a flow rate at least 40% greater than stock.
For customers planning max effort builds, we recommend the greatest flowing HPFP available.
F150-Specific Recommendations:
When to Upgrade / Stock Fuel System Capability:
2.7L F150 (2018+ - Factory Port Injection) Can run up to full e85 with a tune only. No fuel pump upgrades are needed in most cases.
3.5L F150 (High Output - Raptor, Limited) Can run up to e50 with no additional modifications. No fuel pump upgrades are needed in most cases.
3.5L F150 (Standard Output) Can run up to e50 with no additional modifications. For customers looking to run full e85, a fuel pump upgrade is needed.
We recommend upgrading to the OEM High-Output Pump (OEM Raptor Fuel Pump)
