Fuel Pressure Regulator Regulator 15 - 90psi

The MSD Fuel Pressure Regulator 15 - 90psi (MSD2938) is a precision fuel system component designed for hot rod builders, street performance enthusiasts, and serious engine tuners who require reliable fuel delivery under varying load conditions. This regulator is essential for carburetor-fed engines, naturally aspirated builds, and mild forced-induction applications, where maintaining consistent fuel pressure is crucial for optimal throttle response and driveability.

Engineered for mechanical stability, the MSD regulator operates within a wide pressure range of 15–90 psi, allowing users to fine-tune fuel pressure to meet specific carburetor and fuel system requirements. Its robust construction ensures durability and reliability, handling repeated pressure cycling without issues like hysteresis or creep. This design philosophy supports effective fuel regulation across various applications.

Carburetor users will find this regulator particularly beneficial, as it accommodates idle circuits requiring lower pressures while also providing flexibility for higher flow applications. The compact size of the regulator allows for easy integration into engine bays with limited space, making it an ideal choice for street rods and performance tuning setups.
