When upgrading injectors and fuel pump to a larger flow setup, the stock fuel pressure regulator becomes inadequate for the required pressures of the new configuration. The factory preset of the stock regulator is non-adjustable, limiting the tuning potential for the car. The TOMEI Fuel Pressure Regulator addresses this by ensuring stable pressures through its oversized diaphragm, allowing for effective adjustments. The Hard Anodized finish provides added protection in harsh environments, safeguarding the regulator from grit, grime, corrosion, and heat. The AN6 and #8 straight fittings included in the package cater to popular fuel piping requirements, offering a hassle-free installation out of the box. Depending on your specific setup, additional equipment or parts may be necessary to complete the installation process.
