another what is this

Unread post by Leroy22 » Wed Feb 08, 2017 4:12 pm

what is that pump for? I'm guessing its for exhaust emission.
the hose piece in the picture is hooked up with the pump.
Can this be removed completely and still run?
Thanks in advance for your help.

it's your air pump. It pumps air into the exhaust ports to help reduce hydrocarbons and carbon monoxide emissions. I can not advise you on defeating federal emissions equipment

yea I understand,anyway its coming off,my truck is an 87 so the smog stuff has been on it for 30 years so its worn out and probably not doing what it is suppose to do anyway, here in Fl. we have plenty of clean air so its not really needed.
