BBK FPR
You adjust the BBK fuel pressure regulator by using an Allen key? That's strange to me, my Accel regulator adjusts with a screwdriver, and the adjustment is on the fitting which the vacuum line connnects to- so you have to removed the vacuum line to adjust fuel pressure. I assumed that all adjustable regulators were like this. The other ones I've seen have had a nut on the same fitting that you adjust with a wrench.
