I think the fuel pump is going out. I want to test the fuel pressure. I can't find the piece where I screw the pressure tester on the rail. How do I test the fuel pressure?
You'll need access to a fuel system test kit.
There isn't a valve. You have to use an adapter that goes in place of the fuel filter
