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.

Thank you,gonna have to check that out, we are all chevy people, But when it comes to vortec. like working on the older styles.

How did you fix that?? any easy suggestions Hate to take it to the shop

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.
