1996 S-10 Blazer 4.3, I am having trouble identifying this part. It's a part of the fuel pump system. Any help would be appreciated.

 

I think your 96 has the same cpi injection as my 95, doesn't it? I've been all through my fuel system, multiple times, and never seen anything like that

 

I believe you are correct on them being the same. This is my son's blazer and he dropped the fuel tank the other day to replace the fuel pump and he came carrying this in asking what it is. I am not sure exactly what it attached to. I am waiting for him to get off work.

 

Maybe a vent of some sort? That's not what my tank vents look like though

 

This is attached to the middle connector on the fuel pump via a vinyl line and also connects to the front of the tank and leads to the charcoal canister. I am trying to find a replacement and cannot find it anywhere on the interwebs! Please help

 

Why not just replace the entire fuel pump and the wiring harness
