These filters are the finest racing style filter available. They flow 130 GPH at 7PSI or 330 at 40PSI and filter down to 10 microns with a replaceable paper filter. Viton o-rings are used throughout and new o-rings are included with element. Two tapped holes are provided for a mounting bracket. Since most installations will require a custom bracket, one is not supplied with the filter. Note that a Barry Grant element for the BG500 Filter will fit in the filter and the 10320 element will fit the BG500.
