Fuel Press Reg EFI 25-90psi 6AN/6AN

The FUELAB Fuel Pressure Regulator EFI 25–90 PSI with dual 6 AN connections is a precision fuel management component designed for EFI systems utilizing gasoline, diesel, E85, or methanol. This in-line regulator is essential for maintaining stable fuel pressure across a wide operating range, which is crucial for consistent fuel delivery and engine performance in modified turbocharged, supercharged, or naturally aspirated applications.

Constructed from durable black anodized aluminum, the 51502-1 model features two 6 AN female inlet ports for supply and return lines, along with a 1/8 inch NPT port for vacuum reference or gauge installation. The adjustable pressure range of 25–90 PSI accommodates high-flow fuel pumps and varying fuel demands without the need for multiple regulators. The anodized finish provides corrosion resistance, making it suitable for engine bay environments.

Engine builders, performance enthusiasts, and fabricators upgrading fuel systems on modified vehicles will find this regulator particularly beneficial. Fuel pressure stability is vital for modern EFI tuning, as inconsistent pressure can lead to lean conditions, detonation, and drivability issues. The wide 25–90 PSI band supports everything from low-pressure street applications to high-boost racing setups without compromise.
