Description

The Cobb High Flow Fuel Pump (COBB315450) is a crucial component for Subaru vehicles requiring increased fuel delivery, especially for Flex Fuel setups. Engineered with robust internal construction, this in-tank pump is designed to withstand the unique demands of ethanol and methanol fuels, being tested for compatibility with fuels up to E100 and M100, as well as all grades of gasoline. This high-flow pump delivers a tested 340 liters per hour at 40 PSI, ensuring adequate fuel supply for modified engines. Its compact, short-body design (65mm length x 39mm diameter) with mounting hooks allows for an ideal, direct replacement of the factory fuel pump in many applications with tight fuel tank tolerances. This fuel pump is a vital part of COBB's NexGen Stage 2 and Flex Fuel Power Packages. This fuel pump is specifically designed as a direct replacement for the factory unit in various Subaru models. It is compatible with the 2005-2009 Subaru Legacy GT, the 2008-2014 Subaru WRX, and the 2008-2021 Subaru STI. The pump is also noted as being 50 State Legal with California Air Resources Board (CARB) Executive Order D-660-105.
