Walbro Intank High Pressure Fuel Pump: 255lph [GSS342]
Walbro fuel pump has been a staple in fuel supply for years now. Compared to the stock pump they are tiny in size but make up for it in high performance flow. With 255 liters per hour of flow they can support upwards of 600hp in an RSX. They are sometimes a little noisy especially compared to a stock pump, but most with aftermarket exhausts you will never hear them.
The GSS342 is designed for high fuel pressure applications and is the go-to choice for most performance builds.
