CNG leaking into intake manifold-2000 Excursion

[Royger]

I bought a 2000 Ford Excursion. It seems to be leaking slowly into the intake. I'll go into detail. The system leaks out very slowly. I don't believe there are any leaks in the system. I'm guessing that it's bleading through the injectors (If you can call it that). I have a home fuelmaker. I noticed when I hooked up the fuelmaker after a couple hours I could smell gas leaking. I traced it down to the intake manifold tube where the CNG system is located. Is there a valve that's gone bad?

On my system (Dodge Caravan) There are 2 Solenoids. One on the GFI high pressure regulator and the second in the engine compartment just before the fuel rail.
