it's a gas leak, not oil...need suggestions!!!
needed to start another thread due to my findings......the supposed oil leak that I though I had turns out to be gas and not oil, so I need some advice on this..... posted are some pics and I will explain where the gas is coming from......
in the first pic, where the black cap is located, there seems to be a bleeder relief under it similar to a tire valve, at the bottom of the stem is where the fuel leaks from...
in the next pic with the black cap removed, you can see a better view of the stem, and where the fuel leaks, it is at the bottom of the stem. I am assuming that is the actual fuel line which delivers fuel to the pump. I am going to attempt to use the Toyota RTV in this area when it completely dries. Is this round disc some type of filter or what does it do??? I may have to get this assembly and replace it....thanks for any imput..........

Our fuel system runs at very high pressure so the RTV isn't going to do anything probably. Have no idea what that piece is but I've often wondered on my own SS. I thought it was a pressure relief valve at first but only one line in, one line out so no way. Maybe a pulsation damper of some sort.

"The fuel delivery system features a high-pressure stainless steel feed line and a pressure-regulated fuel rail, without a conventional fuel return line from the engine to the tank. Fuel pressure varies from about 750 psi at idle to 2,250 psi at wide-open throttle."

If it were me I'd replace the entire assembly rather than relying on an attempt to solder it or some other kind of bodged repair. Even though its only 50-60 psi of fuel pressure, if that eventually fails you'll have a high pressure fuel spray under hood and that could very well lead to a fire and a loss of the vehicle. Whatever you do, be vary careful and wear eye protection because a blast of pressurized gasoline in the face will ruin your day.

A conventional port injected engine needs as little as 60psi, were the 2.0L direct injection system operates at pressure as high as 2250 psi
