A squirrel nested in my engine compartment. I cleaned it all out, and this, what appears to be thermal insulation, was separated.

Is it something I should replace?

It was put in to help with vapour lock in the later model Tjs. Not a bad idea to have it.

I oddly just replaced mine yesterday. Its not a very pricey piece and while I had the intake off I decided to replace mine which had turned into mush.

You’re in high temp country. I replaced mine and put shields on the injectors also when I installed new injectors. Like others said it’s a cheap easy fix.
