Maintenance Update: I was getting an intermittent p0455 code which is for the Evaporative system indicated a large leak, coupled with a “tighten fuel cap” warning across the dash. Started with the easy stuff, a new OEM fuel cap intermittent code still persisted.
Today I installed ACDelco part #212-2339 which is actually a replacement Evap Vent Solenoid for a NNBS truck with the remote filter box.

There is a GM TSB with this system under 02-06-04-037H which calls for using service P/N 19152349 which is a replacement evap vent valve solenoid with a remote mount filter to prevent the filter from being clogged like the factory part since is a vent valve and filter all in one canister.

The problem being if you read through the bulletin, it’s hacked up garbage lol. They want you to replace all the evap lines to the vent valve and remote filter with 5/8” heater hose and hose clamps. That and the fact the service kit is 120 bucks and doesn’t include heater hose and clamps for you.
A little research I was able to find thru another forum (GMTrucks iirc) a guy had used this NNBS kit with success on his NBS. The kit includes all factory parts, evap vent valve, proper evap lines with looming and clips to attach to the brake lines all for 64 bucks on amazon. Since it is from an NNBS truck you do also need a conversion harness for the vent valve solenoid but wouldn’t ya know, ACDelco has that as well for 16 bucks on amazon.

So for nearly half the price of GMs service kit that isn’t complete, you get a complete OEM solution that is literally bolt on and isn’t all cobbled together with heater hose and hose clamps. Why they even offer that service kit instead of marketing the NNBS kit as a retrofit is beyond me.
Regardless, this kit with a new purge valve on the motor and no warnings or codes after a decent drive, hopefully it stays that way.
It’s not very exciting so I didn’t take any pictures but literally bolts on with a new bracket, plugs in with the conversion harness and then find a nice dry spot to mount your remote filter. I slid mine right between the filler tube and the bottom of the bed.
If anyone is having that issue and wants more info or pictures let me know!
