I have a leak that seems to be coming from the power steering pump. Fresh oil has a reddish color. I'm cleaning up the oil and grime to get a better idea on where it's leaking. The manual suggests I have a Saginaw pump but my pump is different and it seems I have something similar to this Motorcraft pump: https://www.summitracing.com/parts/m...SABEgLas_D_BwE
What I'm trying to figure out is how this hose going up to the pump should be connected? On the pump end it's connected using a hose clamp. It could be leaking there and may just be a question of refitting the hose and clamp.
The hose goes down and on the other end of the hose it connects to a metal pipe that runs and loops along a cross member:
Is it supposed to be a regular hose clamp to connect this hose to the pump (1st picture), or is there some special clamp to connect the hose with the pump?
And on the other end where it connects with the pipe (2nd picture), is there supposed to be a hose clamp or was it designed to just have the hose fit over the pipe?
Assuming this is on the end where the hose connects with the pump. Do you also have a clamp on the other end of the hose where it connects with the metal pipe? Or is it like mine in the 2nd picture that the pipe just plugs into the hose?
THIS: Assuming this is on the end where the hose connects with the pump. Do you also have a clamp on the other end of the hose where it connects with the metal pipe? The pipe has a stepless ear hose clamp on it.
It appears to be covered I. Grime and out of line of sight from the hose in front of it, but it looks like it’s either got one that’s riding right above the flare on the tube or the impression from where it was is there and it’s grimes filled in. If it’s there, it doesn’t appear to be compressing much and it looks like a valid place for diagnostic cleaning and inspection
edit; I say it looks to be riding the flare because the hose looks like it’s about an inch down where it was before, probably from a stiff hose that had a weak clamp, so the return pressure jacked the hose downwards to where the clamp is preventing it from sliding off the flare but perhaps is not sealing well anymore.
I would buy 2 constant tension clamps for the use or 2 fuel injection clamps and some 3/8 trans line. I would also do a cooler at this time but that is me. A filter ain’t a bad idea either. Flush too
and since you asked, your truck has a c2 Ford power steering pump. A Saginaw “p” pump was used by Ford till 78 or so and then used for certain applications after that.

Here is a 77 LTD with a 400m
SEe down low? Saginaw
That is a Ford power steering pump. This is a Saginaw pump:
There was a clamp on the rubber hose on the steel return line. It was crimped on?
I recommend installing a worm drive clamp on the return hose since you don’t have anything there and the clean off the area entire area before replacing anything then top off the system with Type F transmission fluid. Otherwise you could end up replacing a good part and still have a leak.

Worm drive especially cheap ones usually eat into the hose over time, but not tightening, so they lose tension. And the hose over time gets stuff and less pliable and it's apt to create a leaky hose.
A expensive or old worm drive is okay, but they aren't everywherd. But. Fuel injection clamp is a like 50 cents for 2 or something from auto store and has a wide band around it which doesn't eat in so bad. And also 4 of them and the right hose makes for a flareless repair on ps return or trans cooler lines
Here is my return hose. The clamp on ta one end and the crimp on the other(commonplace) if you had the crimp ever leak, cut it off, like carefully, cut the hose clean, flare the remaining hard line, slip over and clamp. For future reference

It’s on the return hose. Would a fuel pressure clamp be better? Maybe, but that type of clamp will be fine.

I’m saying from personal experience with a new hose and a new work clamp that it isn’t a robust idea unless the clamp is nicer or different design. Been there lol. Multiple vehicles.
Also, we can’t overlook a potential contribution. Vent in the cap. How old is your cap OP and have you cleaned the vent out at all. They can clog and cause excessive pressure in the return and make something otherwise a sealed line leak a bit
Thanks all. I need to inspect the lower end of the hose where it connects with the pipe as there could well be a clamp around it. And yes, the grime (and pipe) may be camouflaging the clamp.
Just got back from Napa but they only have the regular (worm gear) clamps and no constant tension bands. The hose seems to be 3/4" od so I'll get a tension band for that (may have to get that online).
Unless the pump (and the cap) has been replaced it should/could be the original from 1988 (made in 1987) so it could be pretty old by now. I'll check the vent.
Think I was reading the wrong chapter. In the manual I was reading 13-52 "Power Steering Pump - Saginaw". Didn't think to look at the following chapter 13-53 "Power Steering Pump - CII", which is what I have. May have to do with the manual consisting of over 6000 pages (and me not realizing there's 2 types of pumps).

hydro boost applications usually would have an extra return and a feed off the ps pump too. For Ford I know it means an extra return nipple but I’m not sure how the pressure feeds to it. You don’t have hydro boost so that helps.
E vans and certain equipped trucks would have Saginaw pump. The regular plain Jane f series is c2, which is inferior in my opinion. There is a company that makes the c2 body with Saginaw internals so that it has the benefit of fitting without modifying brakets or looking out of place. lol
