Running a Motorguard with a Permacool universial adaptor on a Ford 4.0 OHC. Drilled the Ralph recommended 7/32 hole through the adapter to eliminate a start up rattle. The filter does not drain and makes a mess at change out time. Can I remove the restrictor to allow better drain back to the block. It is mounted high and shouldn't be this messy. The pressure diff on the in-out should be very low, and shouldn't have too much flow if eliminated. Thanks
