MSI has recently developed a brand new fuel surge tank for the 2002-2010 Subaru WRX/STI. The MSI fuel surge tank is made from 6061-T6 aluminum and is 100% CNC machined for quality and performance. The MSI surge tank can be fully disassembled for easy cleaning and servicing. Capable of running one or two external Bosch 044 fuel pumps and internal or external fuel filters, the MSI surge tank has the option for multiple configurations depending on your fuel needs. The MSI fuel surge tank also comes with the option of a clear acrylic center section for easy viewing.
