It doesn't matter mechanically which order you reinstall the 2 hoses on the long bolt since they are both connected to the same point. The only thing is to route the hoses so there are no sharp bends or kinks and they don't go near heat or sharp edges. Flow and pressure are not the same thing, you could have high flow at low pressure and no flow at high pressure. Now that you have LOW pressure check the primary regulater if it is stuck open, the pump, it may not be able to make pressure, the suction hose, it may be kinked or collapsed, the fuel filter, it may be plugged up. As I expected trying a different Control Pressure Regulater had no effect. If you cannot get the Primary pressure regulated then you can't measure the cpr, it will only work correctly once you get primary pressure correct. You may still have a cpr problem but you can't tell yet!
