The Petrol King (part number PK5) is a reliable and adjustable pressure regulator from the renowned brand Malpassi, specifically developed for engines equipped with carburetors. Unlike its sibling model, the Filter King, this regulator does not have a built-in fuel filter, making it an excellent choice for those who already have a separate fuel filter installed in their system.

The main task of the regulator is to ensure an even and precise flow of fuel to the carburetor. Maintaining the correct fuel pressure is absolutely crucial to achieving a smooth running engine, preventing the carburetor from flooding, and reducing overall fuel consumption.

Tip from Misab: This regulator is essentially a must-have if you are using an aftermarket fuel pump (such as a Facet pump) that delivers a higher pressure than 0.25 bar (approx. 3.6 PSI) to your carburetor.

Technical Specifications:

• Type: Adjustable fuel pressure regulator for carburetors
• Setting Range: Around 0.25 bar (factory set for standard carburetors)
• Connections: 8 mm hose nipples (in/out)
• Gauge Port: No
• Built-in Fuel Filter: No
