SARD adjustable fuel pressure regulators for EFI engines utilizes extra light weight diaphragm assembly that provides excellent pulsation dampening; to dampen the pressure spikes caused by high flow fuel pumps and cycling injectors (especially non-factory high flow fuel injectors). SARD offers two universal regulators, the Type-R & the normal models. Both models comes in either blue-anodized -6 AN aluminum inlet ports with a 1/8 NPT gage port, or blue-anodized aluminum 8 mm inlet with a 1/8 NPT gage port. SARD fuel pressure regulators are designed to provide the correct fuel pressure for any high performance fuel injected vehicle. The normal model is designed to be used on fuel injected, non-turbo-charged engines, and it is machined from billet aluminum. The other universal regulator, Type-R, is more expensive, and is designed for fuel injected and turbo-charged engines. Due to its boost compensating design, it can provide more fuel under high turbo boost conditions. As per the normal model, parts are machined from billet aluminum. Pressure adjustment is made easy on both models by turning the built-in 360 degree nut. Both models are made to bolt in the factory location in most vehicles, so installation is a snap!
