I've reused intake gaskets several times. Just inspect them good. On the dye some people have issues others don't. Don't know what the variables are , maybe fuel quality, maybe optics.
The only thing to watch out for is the tiny vent hole on it. Other than that I couldn't find a chemical in my shop that would hurt the diaphram inside.
Around here they're pushing the zip system. It's designed for use in a remote system but they're pushing it for use in regular construction. Recipe for disaster if you ask me.
