    Its a stock 305 if that matters. I think its something to do with egr stuff. I am putting on a new carb and intake. So is it ok to lose that thing and all the extra junk that is under the hood? as always thanks

    I think thats and A.I.R. pump. Is there little tubes going into all of the exhaust ports in the exhaust manifold?

    AIR pump, above it is the AIR Diverter. Just like the name says it all...pumps air into the diverter to the exhaust manifolds. Their usually found on trucks with true duals, no cats.

    There were no true dual exhaust US gas K5's in the 80's, but it is the AIR pump.

    It's part of the fun joy of emissions. If you have inspections/emission checks their, then yea, you'll need it.

    It doesn't hurt anything to leave it , may even help burn unburnt exhaust . You won't notice any real horsepower if ya take it off .

    If you've got a guy to pass you, just take it off. I may be wrong on this, but I think the tubes run into the exhaust manifolds, so you'd have to modify your new headers. Just throw it all in the trash.

    2 ways around that . Buy smog legal headers . Or Weld some bungs onto the headers to attach the tubes too .

    I don't beleive in global warming , but I do believe in following the rules :D
