4-Port Fuel Regulator Black

The 4-Port Fuel Regulator Black (MP-9450-BLK) from MAGNAFUEL/MAGNAFLOW Fuel Systems is designed for builders and enthusiasts who require precise pressure control in modified fuel systems. This regulator is particularly beneficial for those tuning carburetors, EFI conversions, or performance fuel-injected platforms, providing the flexibility to balance fuel delivery across multiple circuits.

Featuring four independently regulated ports, this vacuum-compensated regulator allows users to adjust fuel pressure separately for each circuit, which is essential for forced induction builds and complex EFI systems. Its internal design includes precision-machined passages and a robust diaphragm assembly that ensures stable pressure across varying RPMs. The durable black anodized finish also resists corrosion, making it suitable for harsh underhood environments.

Serious street and race builders rely on the MAGNAFUEL multi-port regulator when factory fuel management cannot keep pace with modifications. Its compact dimensions (5.2 x 3.2 x 6 inches) and lightweight construction (1.05 lbs) make it an ideal choice for engine bays with limited space. This regulator is perfect for performance EFI, carbureted setups, twin-carb configurations, and forced induction applications.
