Hi I was wondering what the correct fuel pressure is for a my car? When my brother steps on the gas it acts like it has no power and wants to die. He had the alternator battery and starter checked everything was good. I do not know if you would know but does this car have a fuel filter or is it built into the fuel pump. I have a feeling it is the fuel pump but I have not checked yet. What is the normal operating fuel pressure with just turning the key and starting it. Also when I take it for a drive what should the fuel pressure be. I have looked all over and cannot find what the fuel pressure should be. Also does this car have a fuel pressure port. I have a master fuel pressure tester. If it doesn't have a fuel port where do I connect the fuel gauge at. Thanks.

Hello,

You will need a special adapter I don't know if your gauge kit has it you will need to check.

Here is the specs and a diagram on how to do it.

Pull circle clip upward to unlock fuel line
Install a fuel pressure gauge with appropriate adapters.
Open shut off valve on fuel gauge.
Switch ignition on and off repeatedly until fuel pressure stops increasing pressure.
Read fuel pressure on the gauge.
Specified value: 3.5 to 6 bar

Please let us know what happens.

Best, Ken
