1999 Chevy Blazer 4.3L V6 - Bad fuel line o-ring
At first I thought there was a crack on top of the spider injector unit. After removing the fuel lines I found a torn o-ring and did not notice any cracks on the spider injector. I also did a little research and found that I was missing a stainless washer between the black o-ring and the yellow o-ring. I guess the mechanic who replaced my fuel pressure regulator forgot to put them back. I'm just surprised it didn't create a problem for over 5 years. Looks like I'll be heading to the dealer in the morning to find the kit. The order of installation for the rings and spacer are as follows: black o-ring, washer, yellow o-ring, and then the spacer. ***UPDATE*** The o-rings can found at the dealer or parts store.
