Smog Pump Setup

Before I start removing items off of this engine I got, I need to make sure that I am removing just smog pump related parts. So I have some pictures, please tell me if it is smog pump related. I already know what the smog pump is on the bracket, I'm planning on gutting it so I don't have to find and buy a pulley. And what size bolts do I need to get to plug the holes in the exhaust manifolds?

I want to say that 1/4 NPT brass plugs worked great for me. Not exact but brass conforms really well and did the trick without any leaks.

Edlemann 120500. Got mine at Oreilly for $1.49 IIRC. The brass pipe plugs also seem to work but for a few dollars I just got the proper fittings.

Re: Smog Pump Setup

The CORRECT size is 5/16" inverted flare. The threads are something like ½"-18 but I can't recall the exact thread specs off the top of my head.

The pipe plugs GD posted are quite close to that thread; close enough, that when liberally globbed up with Teflon tape, they seal just fine. Just don't over-tighten them; only, enough to mooosh the Teflon tape, and call it good.

Well S.O.B., I ordered 1/4" on the 30th.
