you could maybe just tape it up to pass inspection if need. i could be wrong but now that i think about it i am almost certain it is only used to pump air into the exhaust to make the exhaust burn cleaner. could maybe even toss some split loom on it as long as it is not the one by the exhaust that is leaking.

Header reccomendations
I fought the exhaust recirc lines for hours today. Im transferring my registration to a non emissioned address and going with headers and duals. I cant even clean the engine with all the vacuuum crap in there. Pulled the air pump and going back completely old school so I can work on this engine with what I know. So exasperating! I want a trouble free set of headers and am asking for reccomendations for an 85 w150. Seems kinda tigjt on the sides.

you don't have to go with headers. you can just plug the wholes in the manifolds and it should make things all fine. do they actually test the emissions of the truck or is it just a visual? it might still likely pass without all the stuff just because the pump really doesn't do much. the only thing they might look for is the egr valve and cat.
