In-Tank Electric Fuel Pump

The Walbro / TI Automotive GSS line is recognized as the Gold Standard for high-performance fuel pumps. This particular GSS340G3 model is a 39mm in-tank electric fuel pump with a centrally located inlet configuration. It delivers a robust 255 lph flow rate and is engineered to support up to 550 horsepower, operating at a standard 40 psi (final fuel pressure determined by the regulator). Its compact dimensions allow for installation into existing hanger assemblies without requiring modifications. This fuel pump is constructed with a tried-and-true gerotor design, known for its durability and performance, making it particularly suitable for supercharged engines. While the pump is compatible with a wide range of vehicles, including popular Acura and Honda models, it is important to note that installation without adequate pre-filtration can lead to early failure not covered by warranty. The manufacturer recommends using an installation kit that includes a depth media filter for proper pre-filtration and a wiring harness for secure electrical connections. Options for such universal installation kits are available. For optimal performance and longevity, it is crucial to purchase from an authorized dealer, as there is a high rate of counterfeit products in the market. The GSS340 model has been revamped and reintroduced as the G3 series.
