COBB High Flow Fuel Pump – 2022-2026 Subaru WRX / 2020-2026 Outback XT/Wilderness

Description:

Cobb High Flow Fuel Pump 2022-2026 Subaru WRX / 2020-2026 Outback XT

The Cobb High Flow Fuel Pump for the 2022-2026 Subaru WRX is a direct drop-in replacement for the factory in-tank fuel pump, providing increased fuel delivery capacity for flex fuel, high injector duty cycle, and high-power builds where the factory pump's flow rate becomes a limiting factor.

• Prevents fuel pressure drop at high flow rates
• All hardware included

High-Flow In-Tank Pump for Flex Fuel and High-Power Builds

The fuel pump's job is to deliver sufficient fuel volume at the required pressure to keep up with injector demand under all operating conditions. At high power levels on E85 or high ethanol blends, the fuel pump faces significantly higher demand than on gasoline ethanol requires approximately 30-40% more fuel volume than gasoline to make equivalent power because of its lower energy density. A high-flow fuel pump ensures the fuel system can supply adequate fuel volume to keep up with injector demand even at the highest boost levels and fuel flow rates, preventing the fuel pressure drop that causes lean conditions under sustained high-power use.

Drop-In Installation and Fuel Delivery Capacity

High-flow fuel pumps are drop-in replacements for the factory in-tank pump they use the factory fuel pump housing and electrical connector without modification. After installation, a fuel pressure sensor and Accessport monitoring confirm the pump is maintaining correct rail pressure under all conditions. For flex fuel builds on E85 or high ethanol blends, a high-flow pump is generally considered a required upgrade when power levels increase beyond what the factory pump's reduced fuel supply margin can support.

Why Choose Cobb Tuning

Cobb Tuning has been developing performance software and hardware for turbocharged enthusiast vehicles since 1999. Founded in Austin, Texas, Cobb built its reputation on the Accessport and expanded into a full catalog of hardware engineered to complement it. Every OTS map is developed in-house on real vehicles, and every hardware product is validated as part of a complete system not sourced and sold in isolation. That integrated approach is why Cobb produces consistent, reliable results across the builds we see every day.

The RallySport Take

The Cobb high-flow fuel pump for the 2022-2026 Subaru WRX is the fuel delivery foundation for any serious flex fuel or high-power build. The factory pump's flow margin is adequate for moderate power increases but becomes a liability on E85 or E30 blends where significantly more fuel volume is required. The drop-in design uses the factory housing and connector.
