Assuming the car's electrical system is 12 volts, the answer is 12 volts??
36.4 psi
Inside the gas tank.
The fuel pump is located next to the tank behind the right rear tire.
I'm pretty sure it should be around 36 psi.
I own a 1977 280Z automatic and the fuel pump relay is located above the kick panel on the right passenger's side floor in front of the door. You have to access it from under the dash.
The outlet. Most fuel filters are built so that the hermetically sealed end is the OUTPUT. The rounded end is the INPUT.
I have a 74 260z and it's next to the passenger's right foot, just in front of the door. Hope that helps!
Gas in the oil of your 1975 Datsun 280Z can be caused by several issues, primarily a faulty fuel injector or carburetor that is leaking fuel into the engine. Additionally, worn piston rings or valve seals can allow fuel to bypass into the oil system. Another possibility is a malfunctioning fuel pump that may be delivering too much fuel, leading to excess fuel mixing with the engine oil. It's crucial to address this issue promptly, as it can lead to severe engine damage.
fuel filter may need to be replaced or the fuel pump is going out. check all of the fuel lines for moisture. wooden clothes pins work best for checking the lines
temp sensor going bad will cause the engine to dump fuel and foul plugs very quickly.
Nissan 280z's and zx's had external fuel pumps around that psi, and Ford's from the 1980's had external fuel pumps (but it had a higher psi).
The fuel pressure for a Datsun 280Z typically should be around 30 to 36 psi (pounds per square inch) at the fuel rail. It's important to check the specifications for your specific model year, as slight variations might exist. If you’re troubleshooting, ensure the pressure is within this range while the engine is running and that it holds steady when the engine is off.
