Without a reliable and consistent fuel pressure, your ECU has no way of knowing how much fuel it is injecting into each cylinder. Most conventional fuel pressure regulators use a bladder-type design. Although the bladder-type design is cost-effective and reacts to disturbances quickly, those bladders often lead to significant pressure fluctuations, which are manifested as a bouncing needle on your pressure gauge. The Hybrid Racing fuel pressure regulator features a piston-type design that introduces damping into the regulator to reduce pressure fluctuations and needle bounce, giving you a more stable and reliable fuel pressure. Constructed from aircraft grade 6061-T6 aluminum and 304 stainless steel, each regulator receives durable Teflon impregnated, hard anodized finish and redundant seal quad o-rings for improved performance and longevity. The end product is a regulator that keeps your fuel pressure consistent and looks good doing it. Each regulator comes supplied with all of the fittings you’ll need to hook up either a return or returnless fuel system with -6 AN lines. The regulator can accept up to -8AN lines. (Package includes: x3 -8ORB/-6AN fittings, x1 -6ORB/-4AN, x1 1/8th NPT plug, Nylon vacuum port, anodized billet mounting bracket & hardware).
