MANUFACTURED IN ITALY

Genuine Malpassi 'Petrol King' Fuel Pressure Regulators are designed to improve a carburetors fuel feeding system. They were used as OEM equipment by Europe's leading automobile manufacturers such as Rolls Royce, Lancia and Maserati.

Proper fuel pressure and consistent flow are critical to any gas-powered engine. No matter the type of fuel pump used, your engines overall performance and operation will benefit from a properly installed and tuned fuel pressure regulator.

Petrol King regulators eliminate excessive and pulsating fuel pressure, delivering a perfect idle, and fast/ reliable engine startup. The vehicle will run smoother without loss of performance at high rpm, as the pressure to carburetor will be steady and constant under any running conditions.

Petrol King (CB# 3178) is compatible with mechanical or electric pumps, has one fuel inlet and one outlet for installation between the fuel pump and carburetor. They're pre-set to provide ~3 lbs. of constant fuel pressure and can be easily adjusted with just a turn of the screw.

Installation is a breeze using the included universal mounting bracket/ hardware kit. Malpassi products are manufactured in Italy with only the best materials, accurate machining and quality controls.
