Alright the fuel pressure reg is set to a certain amount lets say 40 psi with 0 vac. As the vacumm increases the fuel pressure decreases because it's easier to spray into a vacumm. Hense less fuel pressure is required. Well when you spray nitrous the kit does the exact opposite of what normally happens it ups the pressure in that vac line to increase fuel pressure. Hope this makes sense.
