FUEL PRESSURE REGULATOR FOR CARBURETTOR - ADJUSTABLE - WITHOUT FILTER ELEMENT

PETROL KING fuel pressure regulator has been designed to IMPROVE CARBURETTOR FEEDING SYSTEM. Fuel flow is steady and constant at any weather, ambient and driving conditions, thanks to its wide and sensible diaphragm inside. A standard fuel pump can delivery a fuel pressure 5 times higher than the useful to feed carburettor, with overload, stalling or starvation of engine and waste of fuel. PETROL KING avoids these problems reducing and regulating the fuel pressure, with a perfect idle, immediate and fast start of engine. The vehicle will run smoother without loss of performances at high rpm, as the pressure to carburettor will be set for the max engine power, plus additional safety percentage, according to the size of thr needle valve. PETROL KING is manufactured with the best materials, by accurate machining and quality controls.


  • For applications with carburettor aspirated engines
  • Compatible with alcohol fuel (E85)
  • Diameter 67 mm
  • 1 x IN connector, 8 mm tail
  • 1 x OUT connector, 8 mm tail
  • Supplied with bracket and bolts for easy fitting
  • For carburettor applications only.
  • Not suitable for high pressure injection pumps/system.
  • Suitable for Weber, Dellorto, Solex, SU, Sromberg, Zenith, Mikuni and similar carburettors
