Qualitec carburettor fuel pressure regulator 2x AN6 / 1x AN6 black

Qualitec adjustable fuel pressure regulator for carburettor engines is designed to provide precise fuel pressure control in carburettor fuel systems. The regulator can be used with many popular carburettors, including Weber, Dellorto, Solex, Holley, and Edelbrock, where stable and accurate fuel pressure is essential for optimum engine performance and reliability. The regulator operates within a range of 5–12 PSI (approximately 0.3–0.8 bar) and is suitable for most carburettor applications.

The internal design is engineered to minimise pressure creep after the float needle closes, ensuring more stable fuel pressure and reducing the risk of carburettor flooding. Its fast response makes it particularly suitable for engines with high fuel demand or motorsport applications where a consistent fuel supply is essential. The regulator is compatible with gasoline, E85, and alcohol-based fuels.

The regulator features two AN6 ORB outlets for the carburetor(s) and one AN6 ORB return port on the bottom. The dual outlets make it suitable for both single and dual carburettor setups, as well as V8 engines with dual carburettors. If only one outlet is required, the second port can easily be plugged using an AN6 plug. The integrated 1/8"-27 NPT port allows a fuel pressure gauge to be installed for quick pressure checks and adjustment. Mounting bracket included.

The compact aluminium housing is designed for long service life and reliable operation under demanding conditions. The stepless adjustment allows precise fuel pressure tuning to match your carburettor and fuel pump.
