Today i removed all of my smog pump stuff but i don't know what the plug the stock headers with until i get aftermarket ones. I tried to go NAPA to find a bolt to put it there and by following their chats its a 14mm 1.5 thread but they don't have it !!! so i went every where and cant find anything with those deminsions what should i do. i don't really wanna break those air railings cause i might need them in the future. any responce would be appciated!!

 

you dont need to plug them you can leave the stock AIR fittings in there

 

I had to get those stupid tubes out of there they take up too much room

 

3/8"
?

 

1/8" NPT pipe plugs, need 8 of them.

 

i used jbweld

 

You can just leave them in there and cap the main tubes with a 5/8" (i think) pipe cap. I did this to mine, but it's just temporary until I get the headers on.

 

If you follow the lines up, they all come together before they go into a check valve. Take it off there. You will need a 1" wrench and a adj wrench. Unscrew it and put on a brass fitting. Once it fills up with pressure it will not cause any turblance. I did it to mine.

 

I just did this on a buick..I took the tubes out of the manifolds...trimmed them to the fittings and then welded them shut. Screwed the fittings back in like little plugs
