Malpassi Petrol King Fuel Pressure Regulator – 1.5–5 PSI

The Malpassi Petrol King fuel pressure regulator is designed for vehicles fitted with a carburettor and an electric fuel pump. It reduces and regulates the pressure supplied by the pump to help maintain suitable fuel delivery to the carburettor.

Electric fuel pumps often provide more pressure than a carburettor requires. The Petrol King helps stabilise fuel pressure to support consistent engine operation.

Benefits & Operation

The Malpassi Petrol King regulator is designed to optimise fuel delivery to carburetted engines.

• Helps maintain stable fuel pressure despite changes in temperature and ambient pressure.

• Reduces excessive pressure that may be supplied by some electric fuel pumps.

• Helps limit issues caused by unsuitable fuel pressure, such as carburettor flooding or irregular engine operation.

• Supports a stable idle, efficient starting and smoother driving.

• Helps maintain suitable fuel pressure at high engine speeds, depending on the carburettor and needle valve specifications.

Applications

Ideal for classic vehicles equipped with a carburettor and an electric fuel pump. Check the fuel pressure requirements of your carburettor before installation.
