Silly question, I know, but can someone help me ID the PS pump in my 1972 Swinger w/318?

The car is currently at the shop having the transmission completely rebuilt, and I'm stockpiling some parts for when I get it back. The pump leaks, so I'm either going to get a replacement or parts to rebuild it and fit some new hoses.

From my view, it seems to me it's a Saginaw style pump (by the shape, the bolt-on pulley, and the barbed fitting that comes off the side). But I'm no expert. Can someone take a look and tell me what they see here?

I'm going to say its a Federal, but i do think they have a Saginaw that looks the same with the round body. I also want to point out that it isn't a bolt on pulley, its press on.
 
It is also not mounted right. Suppose to use a single 3/8” bolt and a spacer where you have the two short 3/8” bolts. And yes that is not a bolt on pulley. It is a press on.
 
Thanks for all the help! Looks like I'm going to need a pump, a tool to pull the pulley, and the long bolt/spacer setup.
 
Those are unique in that the normal installer for the pulley won’t work. Unless the shaft on your new pump is threaded. It has to be pressed on with the pump can off.

Crap. So even if I get a reman pump, I have to pull the thing apart to change the pulley? That's not simple and convenient! Looks like my new strategy is to wait till I get the car back and make damn sure the leak is from the pump and not just the hoses.

Thanks.

Unless the Renan company is wise enough to thread the inside of the shaft so a standard installer tool can be used. Yes make sure where the leak is coming from.

From your photos, it looks to me that you have a threaded shaft pump. If that's the case, you can get a puller for the pulley, and use a bolt and washers/sockets/ to install it on the new pump. Some new and reman pumps don't come with a reservoir anyway, so pulling it off the old pump is required. They come off easily so it's not a big deal....just messy! As for checking for leaks, yes, clean everything up good and check for fresh oil leak(s). If the reservoir is dented or damaged, it can very easily leak around the "O" ring seal. The shaft seals are also a common place to leak. If the pump otherwise still works fine, I'd just reseal it. They're not hard to do.
 
Great information. I'm now convinced I have to wait to get the car back from the trans shop to see what I'm working with (thread or no thread in the shaft, is it really leaking, etc). Not as simple as just having it on hand to swap out once I get the car back.
 
In case anyone was biting their nails waiting for the gripping resolution to this, I got the car back. I got a new pump, pulled and pressed the pulley onto it, put in a long bolt with a spacer, and wrestled it all in.

But it all might have been for nothing -- I also got a new pressure hose, and when I pulled the old one, it seems the guy who put in my engine didn't put the o-ring on the old pressure hose-to-pump fitting. I find it very odd that Mopar didn't just do a regular flare fitting there (if flare is good for the pressure of brake fluid and so many other things, why not for power steering?).

I haven't filled and started it yet -- I have to bring some sheets of cardboard home today to protect my garage floor if it all goes bad. Which gives me a day to obsess whether I put that o-ring in correctly. Pardon the terrible artwork, but does this look right?

Some lines used the O-ring set up, and some used the inverted flair. You just have to remove the line to see which one you have.
 
O-Ring offers a more simple seal solution that a flare. And it is serviceable with a simple o-ring changeout. if the flare got buggered or cross threaded, the thing would have to come out and get serviced on a bench. PS pumps can be 800 psi, plenty of pressure to find a weep point in a compression type seal. No one likes a leak ask a Jag or Harley Davidson owner.....
 
Got it all together and zero leaks. Thanks everyone. Never noticed this before, but my pulley isn't exactly true -- has a little warpy wobble to it. The belt is running fine and so I'm not too worried, but probably on the prowl for a new pulley at some point in the future.
