Thanks grumpy for that too, I think mine cleaned up okay but I might just get one for the hell of it!

I have one with just the straight through fitting on it. No screen. It may be from a 1969 but I am not sure. Still has the tower clamp on it so I am fairly certain it's OEM. When did GM use the flame arrester and when was a plain nipple used?

That one looks like one with very large connection that won't fit in the typical setup. Apparently there are 2 sizes. Picture from GerhardH (click picture for related thread):

I have seen pictures of the plain nipple with hose attached, then inline flame arrestor, then more hose, then the air cleaner or spacer. And I believe some of the flame arrestors were like this and in the air cleaner at the place where the hose attaches.

For our year model trucks and 8-cylinder engine the common setup I've seen in forum pictures is like the one at the beginning of this thread.

If yours looks exactly as pictured in this thread except it has nothing in it, then it is possible it got clogged and a previous owner removed the guts from it instead of cleaning it.

They appear on eBay now and then, that is where I got mine. The listing was pointed out to me by a member here. And they appear in the parts section of this forum now and then.

I believe there are tons of these laying around in people's garages because the stock air cleaner, spacer, hose and flame arrester is one of the first things people rip off their new truck and replace with a chrome open air cleaner with chrome breather on the valve cover, baby chrome does get you home after all and the engine gets an extra 100 HP just for doing that! Not really, just kidding. But it does look so cool.
