'97 Vette Fuel Rails?

Has anyone used one of these on a swap vehicle. I have them on my '94 V6 to LS1 swap and the vaccum line is not hooked up.

Should it be? If so, to where?

what pcm are you using? what calibration.

on a f-car setup, you just leave it open to atmosphere, since they run a 58# static rail pressure, some trucks you need to vacuum reference it.

Do not hook it to vacuum. It is just a run off for leaks. Hook a line, run it down under the rail and out the back past the head and leave it open. It still keeps a constant PSI just like the newer fuel filter style mounts.
