Start by just Teeing Pauls gauge into the supply line, temporary install. Use it to dial in 2 psi or thereabouts, check what your cheapy gauge says(probably zero). Once you get it happy, gently pack Pauls gauge away in your tool box, well protected. If you ever need to verify or change pressure, put the gauge back on. Mine uses rubber hose to the carb still, so I leave 2 chunks of hose and a Tee attached to the gauge, pull it out when I need it. Did a big carter pump come in the mail also? There is a place on the frame rail that the bracket can attach to that will let you mount it upright and still keep it out of harms way. It needs to mount upright. The stock pump wire harness will supply enough juice to run it without popping fuses or anything, at least on mine.
