v8 EFI engines 35 to 45 psi
96 EB Bronco 5.8L EFI what is the standard fuel pressure
9 to 13 psi is factory
41 to 47 psi. _____ 10 to 12 PSI as it varies slightly from factory. The answer provided above applies to 1995 and up s10s with the 4.3 v6 and the newly added MPFI fuel injection system. In 1992 the fuel injection system was TBI (throttle body injection). TBI fuel pressure was set at 10 to 12 PSI from the factory.
i believe it should be around 6 psi that's what mine was at after i installed my new pump
For a 1995 Ford Explorer , 4.0 liter , EFI , V6 engine : With engine idling ( 30 PSI ) Key On / Engine Off ( 39 to 40 PSI )
When I put a fuel pressure regulator between my stock fuel pump and carb, I found about 5psi gave me good results
I'm looking for the factory specification which when measured is taken at the fuel rail port. Also what is an acceptable range if any?
35-55 psi per factory service manual.
The fuel pressure for a 1987 Suzuki Samurai typically ranges between 28 to 34 psi (pounds per square inch) when the engine is running. It's important to ensure that the fuel system is functioning properly, as incorrect pressure can lead to performance issues. Regular maintenance and checking of the fuel pump and filter can help maintain the appropriate pressure.
The fuel pressure for a Suzuki Samurai typically ranges from 28 to 38 psi (pounds per square inch) at the fuel rail. However, this can vary slightly depending on the specific model year and engine configuration. It's important to check the service manual for your particular vehicle to ensure accurate specifications. Maintaining the correct fuel pressure is crucial for optimal engine performance and efficiency.
Fuel pump pressure depends on which fuel system the car has. If your car has a carburetor then the fuel pressure should be 9 - 13 psi. If your car is fuel injected then the fuel pressure should be about 45 psi.
