I just installed 1 on a 300x very simple -except the instructions were wrong . the bolt on mount has 3 options to bolt the valve to , I followed directions called for middle of mount, and they clearly state want for any thing hitting -1st time in use - well I snapped the fitting out of the cylinder ,the hose hit the valve. changed location of the valve to rear part of the mount and have plenty of room -just a $300 cylinder repair
and go to auto parts store and get a fuse holder that ads a circuit
