Power Steering Pump
How well did the power steering pump from the F-450 install in your 76 F-250? I just put hydroboost in my 77 F-100. I used the booster from a 2008 F-250 and adapted to my factory 77 F-100 pump. The F-250 calls for Mercon V fluid and my 77 calls for regular old power steering fluid. I flushed my system and went with Mercon V assuming the booster would be the pickiest component. It doesn't seem to be working perfectly and now the pump is doing the classic ford power steering whine. I was thinking about getting a pump like the one from you f-450 and trying it out but I don't want to have to reengineer my entire accessory pulley system to do so. Let me know what you think.
Thanks!
P.S. I suppose let me know what fluid type you ran too. Thanks again.

Hi, For a year I used a Saginaw Pump then switched to a Borgeson. I was having trouble with the pedal not returning and when it was really cold out the PS wouldn't work for about 60 seconds. And of course the Saginaw whine. If you look at
WILD HORSES 4X4 Off-Road Bronco Parts and Accessories they have the pumps, bracket and pulleys, I ended up just calling them and they helped me get the right setup "duel return and stuff" and were really nice guys.
If you use the Borgeson it takes PS fluids not transmission, I went one step further and put in synthetic.

Sweet! Good info. I just bought a power steering pump from a 2000 f-350. I'm not sure if its a Saginaw or burgeson but from what I can tell with a few measurements, it has the same mount holes and pulley shaft as my original. It also has the dual return ports. I will know better in a couple of days how well (or not) it works. I'm also having an issue with my pedal fully returning. It's not far off, only about a half inch, that's enough to keep my brake lights on. I used my original master cylinder but I'm also wondering if the pushrod between the master cylinder and the booster is not the right length for my set up. I used the rod that came with the hydroboost but I'm considering swapping it with the one from my original vacuum booster. We'll see how it turns out. If that is not possible or doesn't fix the issue, I have the master cylinder that came with the hydroboost that I may try. Obviously its for a disc/disc setup but I have an adjustable prop valve that I have been wanting to install anyways. Will update when I get more done.

Compare the rod hole in the master cylinder piston. There are two types. One is a shallow hole which works with hydroboost. The other is a deep hole which is usually used on vacuum boosters. The rods from the boosters are not interchangeable. Someone makes an adapter plug that fits the deep hole so the master cylinder can be used with a hydro booster. It looks like a bullett with two o rings on the outside of it to hold it in place. I can not recall where I saw it but it was either Jegs or Ebay. This is one of the reasons you do not get full pedal return.

I finally got mine working. I ended up putting in the master cylinder from the same '08 F-250 that i got the booster from, along with a new prop valve with an adjustable rear and a 10lb residual valve for the rear circuit. I'm running a pump from a '00 F-350 and it's working WAY better now. Very firm pedal feel and amazing stopping power. My only issue now is the pump is incredibly noisy. I'm getting the typical Ford power steering pump whine but it's a brand new pump. Thinking I may have bought a lemon, i took it back to O'Reillys and swapped it for another. Same thing. Now i'm kind of just hoping that maybe there's still some air trapped in there somewhere that will work its way out soon. I know, it's a long shot, but here's to hoping. If not, i suppose I'll look into a pump from a old lincoln. It seems like i saw that someone used one of those either on this thread or another. I will be going back through and reading again to see if i can find it. If that fixes it, it will still be cheaper than any of the hydroboost kits i found. I'm in it for about $350 or so right now. Another $75 or so for another pump is doable...disappointing, but doable. I'll try and post a photo but i've never done that here so we'll see if it works. Lol.

I have a question..im using a hydroboost off a e450 van. Do i have to drill new holes in the firewall to mount this thing? Because it wont line up with the current bolt holes..they are too far up.

I got my hydroboost in but the pedal rod is bent down BUT it still pushes in when i push the brake pedal.
Had to grind some of the bend out of the brake pedal to get the pedal rod to line up better.
What does everyone think?

I think your nylock is worthless. There are thin ones that may work out better. If there isn't at least 1.5 threads out of the end of the nut it will not hold.
I'm working on a setup right now that should allow me to keep my cruise cancel switch.
