Yes, it sure sounds like you have a fuel leak under the plenum. Inside the intake. Apparently the plastic lines are a popular leak to have. Mine was leaking very slightly a number of years ago, but yours sounds like a huge leak.

After 2 garages misdiagnosed it and didn't convince me that it was a fuel pump I checked it out myself. After diagnosing it , I pulled off the plenum and seen a tiny pinhole in one of the plastic supply lines . I got a new line set and just replaced it.

I have heard it called "nut kit" or something like that, it seems to be a common problem. Mine was a number of years ago.

Here's a thread that may apply and help, there are other threads that describe the pressure test.
