I noticed that the air pump on my S5 91 N/A has a hole in the back leaking air, I need to do smog soon and ive never noticed this. Is this a problem and should i replace the pump?

 

don't worry about it

 

It's for a wick.,.,you fill it with gas,light wick and toss the pump at a Honda..lol!

Seriously though If you want to check the pump just take the hose off the outlet and turn the pulley(somehow or start engine..be Careful.!)..if you feel air it is Ok.

 

I found my other air pump and I spin the pumped it seems like air also comes out of that little hole,



This little hole releases air but seems like its normal

 

see above

 

Thanks for confirming it not being a problem
