The regulator body is CNC-machined from 6061-T651 aluminum and ships with multiple springs to cover low, mid and high pressure ranges. The package includes AN fittings, stainless braided lines, and a 0–160 PSI gauge to make installation and adjustment straightforward for most EFI systems.\u003c\/p\u003e\n\n\u003ch3\u003eWhat parts come in the PQY regulator kit and how do they simplify installation?\u003c\/h3\u003e\n\u003cp\u003eThe kit arrives with the regulator, a pressure gauge, two alternative springs for different pressure bands, multiple AN fittings and braided feed\/return lines.
