Delivery Nationwide - Door to Door
This is a brand new, affordable OE Specification aftermarket replacement product. 100% Factory tested and built to strict quality control standard to ensure high performance and guaranteed to deliver better fuel economy.
The fuel pressure regulator is a device designed to maintain a constant fuel pressure for proper fuel atomization. The fuel pressure regulator is able to maintain proper fuel pressure to the vehicle it has been designed for because inside the regulator housing there is a spring pushing against a diaphragm, the spring pressure has been pre-set by the manufacturer for the desired fuel pressure, so the fuel pump has to pump enough fuel and enough pressure at the same time to overcome the spring pressure. The extra fuel not needed is sent back to the fuel tank through the fuel return line. When the vehicle is at idle, there is less pressure against the fuel coming inside the regulator because the fuel pressure regulator has a vacuum hose attached to it, this way the fuel pressure will be lower ( from 5 to 10 psi depending on the system) due to the fact that the vacuum is forcing the diaphragm inside the regulator housing to have extra pressure against the spring, resulting in a lower fuel pressure when the car is at idle because there is high vacuum inside the intake manifold; when you accelerate and the vacuum drops, the fuel pressure increases to allow the engine to have more fuel as it needs it.
Lack of fuel pressure, excessive fuel pressure, black smoke and rich engine running condition, instant drop of fuel pressure once the vehicle has been turned off, delay building sufficient fuel pressure.
