it came as a full unit
Spiders were replaced because of a crack on spider for Cyl1 causing a miss fire. After taking them out almost all tabs were broken off and missing.
Just pulled intake off and cycling the pump resulted in NO leaking in intake. Nothing came out of pressure valve. Cycling pump 4 times for 2 seconds does not result in any leaks into intake.
I have cloth rags laying all over the intake and nothing is wet. Could the fuel pressure valve be bad but not leaking?

A general comment for anyone else reading this.
This is one of the reasons that I don't like the parts cannon. You can actually add to your problems ripping out a perfectly good OEM AC Delco part and replacing it with a crappy aftermarket clone. If this happens and this was not the original issue, now you have two problems. Sometimes detailed analysis is impractical, especially for the shade tree mechanic and an educated guess is required but this should be kept to a minimum.

In your case you may very well have needed a spider but I am just driving the point home that a replacement does not automatically take that component off of the table. The infant mortality rate of parts store offshore replacements is significant.
