Default Fuel rail/injector leaking, maybe?

Hello, I had issues with my car starting, and it seems that I might be leaking some fuel, and loosing a pressure. I removed plastic cover on top of engine and looked at back of it, and it I could smell gas and see very little gas all around there. I am not sure whether this is fuel injector, or something on the rail, or line is leaking. Has anyone had same issue, can someone advise what can be done to test. I am attaching couple pictures of how it looks under the hood.

There is a valve on the fuel rack - same type as for a tire. Mine was leaking fuel there and found the valve to be clogged with a piece of rubber from the cap. Looks as if it some sort of a one way valve in the system. Anyway, I repaced it with a tire valve and all well now for at least 3 years. You may need valve tool - $ 5 or so for the kit.

It should be under the black cap.

I would just tighten the black cap/cover in most cases that's all that need to be done. That valve is how the pressure is tested for the fuel system sometimes the cap comes loose and just needs to be tightened. If the o ring is forcing out the gas just reseat the oring and tighten the cap.

Thank you for your feedback. A couple of questions:
1. Black cap, is that the one on the center of fuel rail, and has a has on top flat screwdriver grove?

2. When you said you replaced the valve, was it under that black cap, or by the fuel injector, and did you had to remove valve cover to access them?

Be careful if you’re going to remove that valve it's under pressure from the fuel pump in order remove relieve the pressure first; but try tightening the cover and see if that works.

thank you all for feedback. After spending couple days taking things apart, cleaning and testing, I found that the valve on the fuel rail was leaking. I got one from tire shop, replaced with this one, and so far the car has been working fine. I did not even needed a tool, just a long needle nose pliers worked great.
