Question type: Maintenance & Repair

I am working on a 2008 Silverado with 5.3 V8. I am trying
to perform a smoke test I the EVAP system but cannot
locate the test port. I feel stupid for asking but does
anyone know where it is located? I've been looking for an
hour now with no results

I was actually referring to the same block as you just stated. There is only about 8 inches from that to the firewall and there is no test port in that location
