The Chevy 350 needs at least 8 psi of fuel pressure to operate properly. If the fuel pressure is too low, the engine will run lean and may eventually stall. A loss of power may also be noticed when climbing hills or accelerating.
The Chevy 350 is a V8 engine that was first introduced in 1967. It was designed as a replacement for the 327 engine and quickly became one of the most popular engines in Chevrolet history. The 350 remained in production until 2003, when it was replaced by the LS1 engine.
The fuel pressure requirements for a Chevy 350 vary depending on the year and model of the engine. Early models (1967-69) require 6-9 psi of fuel pressure, while later models (1970-2003) require 10-12 psi. Most aftermarket fuel pumps will provide adequate pressure for any model 350 engine.

Chevy 350 Low Fuel Pressure
If you have a Chevy 350 with low fuel pressure, there are a few things that could be causing the problem. The most common cause is a clogged fuel filter. If the filter is clogged, it will restrict the flow of fuel to the engine, causing low pressure.
Another possibility is a faulty fuel pump. If the pump isn’t working properly, it can’t deliver enough pressure to the injectors. Finally, a weak injector can also cause low fuel pressure.
If an injector is only partially open, it won’t deliver as much fuel as it should, resulting in low pressure. Whatever the cause, low fuel pressure can lead to engine problems so it’s important to diagnose and fix the problem as soon as possible.

What Should Fuel Pressure Be in a 350 Chevy?
Assuming you are referring to a stock 350 Chevy engine in a car from the 1970s, the correct fuel pressure is 10 psi. If the pressure is too low, the engine will run lean and may overheat. If the pressure is too high, the engine will run rich and may also overheat.
How Much Fuel Pressure Does a Carburetor Need?
A carburetor needs fuel pressure to work properly. The amount of pressure needed varies depending on the type of carburetor, but most need between 3 and 5 psi. Without enough pressure, the carburetor will not be able to draw fuel from the tank and will not work properly.
What is the Normal Psi for Fuel Pressure?
Your car’s fuel system is responsible for providing the engine with the right amount of gasoline. The key component in this system is the fuel pump, which is responsible for moving gasoline from the gas tank to the engine.
The pressure that the fuel pump produces is measured in pounds per square inch (psi).
While there are different types of fuel pumps and each one has its own range of acceptable pressures, most modern vehicles have a fuel pump that produces between 30 and 60 psi.
If your vehicle’s fuel pressure is outside of this range, it can cause problems with starting the engine or maintaining a consistent idle speed. If you think your car’s fuel pressure might be off, you can have it checked by a professional mechanic.
How Much Fuel Pressure Does a Chevy 305 Need?
A Chevy 305 engine needs between 10 and 15 pounds per square inch (PSI) of fuel pressure to run properly. If the fuel pressure is too low, the engine will run lean and may eventually stall. If the fuel pressure is too high, the engine will run rich and may also stall.
Conclusion
The Chevy 350 engine requires fuel pressure between 6 and 9 psi. This range is adequate for most applications, but some high performance engines may require up to 12 psi.
