The Fuel Pressure regulator is normally mounted to the back of the passenger side head, right above where the the heater hoses will need to run. I decided I wanted to relocate it so I had more room back there. The hoses have been temporarily connected in preparation for the first start, but it is just hanging in mid-air there. You will also notice the hoses are currently much longer than needed. That allows me to play around with different mounting location ideas. Once it finds its final home, the hoses will be shortened.
