The COBB Tuning Fuel Pump Holder has been designed to allow users to upgrade their fuel pumps to a larger sized fuel pump without having to modify the factory fuel hanger. With this Fuel Pump Holder, you can now successfully upgrade to several different types of direct drop in fuel pumps without making too many alterations. This holder has been made of high-grade Delrin materials, and will not break down due to the elements of ethanol, or race gas.
