air pollution pump , what does it do for the engine , i think it does something for the emissions , and my dad says it helped with fuel consumption cause we filled the tank last week and drove it to were we should have filled up again and we still have decent amount of fuel remaining . more then we should have to were even i was like WTF mate?

 

If you live in an emission rule state, keep it. If noit take it out.

 

eh i already replaced it so it dont matter but my dad thought it helped the fuel , and how do ya take it off , just take it off ... ?

 

I found this thread.
This might explain it.
