I'm looking to get rid of the what I can only assume is the air injection pump on my 89 d100. Is there anything in the vin that says that it should be present? Because the pulley is making a god awful noise and id rather remove it than buy a new one if I can help it

 

it depends where you are from... here in PA, i have to keep mine as its part of the emissions system, which is inspected during our yearly inspections.

 

the previous owner on my 86 just took the belt off it and left it to free wheel. im happy with it like that. it just spins with the air thats pulled by the fan. i tell people that its electric when they see it spinning.

 

Never thought about that royal haha! I was gonna plug the tube since it doesn't line up with the cat but It always made a horribe noise
