Product Description

The Walbro F90000262 is a high‑performance universal in‑tank electric fuel pump designed for upgraded fuel delivery in gasoline‑powered vehicles. It is engineered to deliver approximately **400 liters per hour (~106 GPH)** of fuel flow at typical operating pressure, making it suitable for powerful engines with higher fuel demands than stock pumps can support. Its advanced **dual‑channel turbine design** enhances hot fuel flow and overall efficiency compared with conventional single‑stage pumps, and the compact body is suited for in‑tank installations needing increased pressure delivery.

This pump’s robust 12 V design and high‑flow capability make it a popular choice for performance and racing applications, especially for builds exceeding approximately **500 horsepower**. Because it is a **universal fitment option**, professional installation with custom wiring, hoses, and possibly a suitable installation kit is typically required. The use of this pump often also involves upgrading supporting fuel system components such as fuel lines, wiring harnesses, and regulators to ensure reliable operation. Due to its higher flow and pressure characteristics, proper tuning and safety measures (like a dedicated relay and fuse) are recommended for optimal performance.
