I have been to Auto parts stores in person, and have now searched Nissan parts and Atsugi's parts stores online and no one seems to have this part. There are alternatives that somehow screws into a hole that doesnt exist on my truck.. Perhaps this is a common problem?? I'm trying to find the problem with my erratic idle. I've changed all my vacuum hoses and my next step has been to look towards heat sensitive parts within the vacuum system (due to its low idle once heated up). But curiosity caused me to remove the VCV and open it up to only crumble a very old filter material inside... It looks like a 5 dollar piece of plastic but it's now seeming more like a treasure hunt...
