Fuel Pressure Regulators for EFI Systems, LS Swaps & Carbureted Builds

Control your fuel system with precision using high-performance fuel pressure regulators from Hot Rod AN LLC. Whether you're completing an LS engine swap, building an EFI conversion, or tuning a carbureted setup, a fuel pressure regulator is essential to ensure reliable and consistent fuel delivery.

Our fuel pressure regulators are engineered to maintain the correct fuel pressure for your application—whether it’s 58 PSI for LS-based EFI systems or 6 PSI for a traditional carb. Maintaining proper fuel pressure not only protects your fuel injectors and carburetor, but also ensures consistent performance under load, boost, and heat.
