Hi... I'm going to say NOT correct for 66 Chevy BB, don't know about the other years. The inlet from the tank is at the wrong angle. As I had said in my previous posting, you have to watch the "clocking" of the inlet versus the outlet. This pump it would be nearly impossible to get the inlet line on....
I have been doing a lot of hunting for a correct looking 65-66 396/427 fuel pump ever since Airtex redesigned their pump and abandoned the original style. They still make a replacement and it looks like crap, fittings are not at all like the original pump was.
I did a bunch of researching at home a few weeks ago and found one that looks very close (slightly different plating) that is sold by O'Reilly Auto in the US. Their website has pictures, looks fine but I was not believing it would be correct because EVERYONE lists their pump as being right, many show the picture of the correct pump but when it arrives it's the ugly piece of crap with the wrong fittings. Well, I took a chance and ordered from O'Reilly's. I told the guy it had to look identical to the pump shown on their website. The pumps came in today, I just picked them up and they look correct (other than no AC logo of course). I'm very excited because other than buying NOS pumps (which I fear will fail because I think ethanol will destroy the old diaphragms) this is the only pump on the market that is correct for 65-66 396\427 (but not the same as L72 427 or L78 396). The only thing wrong is the plating and that can be fixed with a product Eastwood sells I believe.
The O'Reilly pump comes in a Precision Fuel Pump box. The only other place I can find this one listed is on Summit. They want about $20 US more than O'Reilly and Summit has no stock.
The outlet is 1/4" pipe thread so that is identical to the original AC pump. A 90 degree brass elbow was threaded into the outlet from the factory with the female portion of the elbow being a 3\8" inverted flare fitting, pointing straight up. The 3\8" steel line threads into that.

Ooooh. Nice. I should probably buy a couple of those for the l79. They would work for that motor too. What's the part number?
Does the pump you want have a threaded outlet for a fitting to go into that converts it to inverted flare? Or does the pump have have an outlet that is inverted flare and the line goes directly into it?

It like your picture. L79 line comes straight up from the 90 degree fitting. I assume a smalblock and bb pump are the same internals.
I've read guys talking about changing the arm to convert big to small, or small to big. At a glance, I am not sure how a guy would do that though. So I'm tossing this out as a challenge for you to figure out!

Bit of an old thread but I just had someone PM me about the number for the pump I got from O'Reilly's. I guess I never posted the part number. It's an M16210.
