As some of you know it looks like my spider injection system on my 95 jimmy is on the outs. I currently have it off and was wondering if their is a way to properly clean these.

 

run something like carb cleaner or seafoam through them. depending on how much time you have, soak them for a bit, then force some through. when forcing, i'd go AWAY from the nozzel to avoid any chuncky crud blocking it up.
