Breathless Performance Products’ new Adjustable Fuel Pressure for 1985 to 1998 LS1 Corvettes, Camaros and Firebirds, (Item # 100-208) easily installed in about 20 minutes. It is manufactured from 60/61 aircraft aluminum and a stainless steel adjusting screw with a locking nut and a vacuum port manufactured from high-strength brass providing years of use without breaking off. As LS1’s tend to run too rich from the factory, fuel pressures can adjust to provide optimum air/fuel ratios for maximum HP gains --- between 6 to 20 HP depending on engine modifications. For additional HP increases, Breathless Performance Products manufactures custom modified air boxes and lids to increase intake CFM. The same high quality adjustable fuel pressure regulators along with EGR block off plates and modified air lids are available for L98 LT1 models.
Extra gold fitting is no longer used.
