Some of these symptoms include your engine running rough, poor fuel economy and black smoke from the exhaust. On the opposite side, if fuel pressure is too low, your vehicle could experience a lack of horsepower, slow staring, an inability to start the engine or stalling.

How do I adjust my fuel pressure?
When adjusting the fuel pressure, the engine should be at its lowest setting. A screw is held in a fixed position with an Allen wrench while a nut is loosened on a regulator. The fuel pressure can be raised with the help of a screw clock. The way to lower pressure is to turn the screw count clockwise.

What happens if fuel pressure is too high?
Too high of pressure may result in, over fueling of the engine. As a result, this can lead to a rough running engine; poor fuel mileage, and black smoke coming from the exhaust. If your regulator is going bad, your car could display several different symptoms.
What happens if a carburetor has too much fuel pressure?
Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage. In more extreme cases, the float needle and seal in the carburetor can be damaged and gas leaks may occur during idling.
Can high fuel pressure damage injectors?
High fuel pressure results in a rich air-fuel ratio because the increase in pressure forces more fuel through the injectors than required producing increased emissions (HC's) and black sooty exhaust. These excessive hydrocarbons overheat and damage the catalytic converter.
Can a fuel pump have too much pressure?
Using the wrong fuel pump that delivers excess pressure can cause problems ranging from poor performance and lower gas mileage to flooding and carburetor damage. When the pressure is only a little over the required amount, your vehicle may sputter when you first accelerate from a stopped position.
How can I lower my fuel pressure?
- Locate the rubber fuel hose that runs from the fuel pump to the carburetor.
- Install the proper size hose fittings in each end of the pressure regulator.
- Place a hose clamp over each end of the fuel hose.
- Tighten the hose clamps.

What is normal fuel pressure?
It is between 35 and 65 pounds per square inch (psi) on most vehicles.May 4, 2015
What psi should fuel rail pressure be?
No matter what operating condition (short of demanding more fuel than the pump can supply), pressure in the rail will always be 58psi (or pretty close). When idling at 20 inHg, this means effective pressure will rise to 68psi because the vacuum in the manifold is adding 10psi to the rails 58psi.
