so i have a problem my GT is leaking gas but i cant locate the leak i can smell it and see it under the car, but i cant track the drops back to the source. so i was removing the intake manifold and after prying it off with some effort nothing seemed wrong. after i poked around for a while i traked the gas lines into the engine i found what looks like a missing bolt where the gas lines enter the engine. the bolt hole has moved a little from its mate hole under it so obviously the seal has to be broken. so is this my problem and if it is where can i get this bolt.?

Checked the Pontiac 22P manual for the parts you would need, did not find the individual parts listed that you will need. I did find fuel block kit, which includes the fuel block, fuel block seal, and screws (did not list which screws). You could check with a dealer, an they may have more details, and if the kit is still in stock. p/n 17110853, the part is still listed at Monster Parts.
Option two is a trip to pick-U-part.

Here's a recent thread about the fuel block seal : //www.fiero.nl/forum/Forum2/HTML/090145.html

As a guess for the missing bolt- size of 6mm x 1.0mm threads, length maybe 25 or 30mm ?
Maybe someone else has a V6 intake on their workbench and can check the size.

That does not hold the fuel block, it holds the fuel rail itself to the intake. There is an exact mate under the upper plenum, just a few inches towards the drivers side on the fuel rail. It's 8mm X 1.25 thread

Ignore the missing fuel block, this is actually the stock 3.4L fuel rail but the bolts are the same:
