just use the banjo fitting without the check valve ...it goes on the bottom of your crank case where they told you in the bdx instructions to put the bolt...run a line that your comfortable with for routing and fastening with zip ties filling easy..(vertical.)..1/8 id clear line..(same size that came off oil pump)..fill end use a 1/8 barbed fitting with 1/8 female pipe...and then have a 1/8 pipe plug to remove for filling..(plug also isolates the integrity of the crankcase)
