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....

A bit of an update to this-

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.

nice! so this is a 3/8 inlet and a 3/8 outlet? it almost looks like the outlet is for a 5/16?

4SPEED427 · A Poncho Legend!

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.

This picture shows it perfectly.

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?

4SPEED427 · A Poncho Legend!

No, this one is for a big block Dave. I can check their website to see if they have for a small block though.

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.

Hi 4spd427 Can you tell me if this M16210 pump worked out for you? I cant seem to have OReillys ship it to Canada IH

4SPEED427 · A Poncho Legend!

Hi Rob

Welcome to Canadian Poncho! I replied to your private message but for anyone who is wondering I will answer here also.

The pump fit my 66 396 Grande Parisienne perfectly. I don't have the car insured for the road yet but it starts and runs fine in the garage/driveway at least!

LT1Caddy · Poncho Master!

Hi... Yes, the pump works on a 427/454. I have the OReilly pump too.

If it's for your 67 Gary, the outlet is different (if you want to stay totally authentic). The 67 has an inverted flare outlet. The bottom end of the line has a 90 degree bend and the nut on the line threads right into the pump. The 66 has 1/4" female pipe thread for the outlet, a 90 degree fitting with 1/4" male pipe thread screws into the pump and that fitting has a female inverted flare fitting for the line to thread into. The 66 line has no bend at the bottom, it just comes straight down the face of the engine and threads into the fitting that is threaded into the pump.

Big news! I ordered to 66 pumps from James Hinshaw at Hinshaws Chevelle in Elon NC. I asked if he would ship USPS and he obliged as the couriers wont deliver to my side of the road farm mailbox. I ordered it on a Tuesday and it arrived Thursday the next week! And what a pleasant surprise when I saw that they were Precision M16210s!
This solves the whole OReillys doesnt ship to Canada issue.

Well how cool is that! Excellent. You are in business. Bolt it on and no changes needed vs the original pump.

Are you willing to share what the total cost for 2 pumps was sitting at your doorstep?

International Harvester · Member

Yes as soon as I get back the shop Ill check the bill, I ordered 2 pumps, a 66 hardline and a 67 hardline. James doesnt have a website but he sent a catalogue with the order. Just a phone call to order straight from him, no emails lol. Very pleased with the speed.

I forgot to ask, is there a hardware/automotive chain you use for the brass elbow fitting? I figure I might as well update that too.

Cheers

In Manitoba we have Piston Ring stores which are part of the Auto Value chain. I believe they sell Weatherhead and their number for that fitting is 402X6.
