When the regulator does not work correctly the fuel pressure to the engine will be off. Either pushing too much fuel towards the engine or too little. This can, for example, lead to an engine that runs too rich, leading to poor fuel consumption.

In extreme cases leaks in the regulator can cause the engine's cylinders to flood by an excess of fuel. In turn it also contaminates the engine oil. This can cause damage to the engine and furthermore lead to potentially dangerous situations.

Should you experience problems with the fuel supply, then it is advisable to have the system and the fuel pressure regulator inspected and, if necessary, have the regulator replaced.
