WALBRO 525 FUEL PUMP

Genuine Walbro 525 (GSS342) high-flow in-tank fuel pump, rated at 525 liters per hour. This is the industry-standard fuel pump upgrade for turbocharged and high-horsepower applications like the Nissan GT-R R35. 

It supports fuel systems up to approximately 600–650whp on gasoline (lower on E85 due to higher flow demand), making it a reliable choice for stage 2+ builds needing more fuel delivery than the factory pump can supply.

Key Features

• 525 LPH flow rate @ 3 bar
• Genuine Walbro / TI Automotive construction — not a clone
• Brushless-compatible design for consistent flow under load
• Direct fit for most OEM fuel hanger/basket assemblies (installation kit may be required depending on application)
• Suitable for gasoline and E85 (E85 support flow-dependent on build)
