To shorten and simplify the text, for convenience we will call the Fuel Pressure Regulator with the acronym rpb. Your engine runs “lean”, that is, low on fuel, either for an unspecified reason or because it was designed that way by the manufacturer. In this case, if we apply the rpb and raise the fuel pressure even slightly, we will immediately have increases in power that are noticeable even to the least experienced. But if our engine runs very well on carburetion and we install the rpb, we will not have any improvement, or if the engine runs slightly rich and we install the rpb, we will have lost both power and torque. MAX FLOW RATES: 3 bar = 270 lh - 4 bar = 220 lh - 5 bar = 190 lh
