power steering pump
hey folks it's me again. I just posted about my intake manifold gasket. Now I have a question about my power steering pump. It just started leaking real bad yesterday. It is not from the hoses but from the resevor. how hard is it to change out he power steering pump. It is in my 72 f100. I know the engine came from a 79 e 100. When I look at the autozone part for the 79 e 100 it looks like the on I have. The one for a 79 F100 looks different. But what I need to know it what is entailed in the change out?

On my 87 E150 van it wasn't hard at all. Take off the belt, take off the hoses, catch the fluid, couple of bolts to get the pump off.
Consider getting new power steering hoses, esp the high side hose. Sucks to spring a leak there. At very least, replace the O-ring on the hose.

May have to swap the pulley between the old and new units - this calls for a special PS pulley puller to make things easy without damaging the new unit. AutoZone will likely have this available as a tool rental.

the picture of the pump has no pulley. I guess that is what kinda made me wonder what I'm getting into. They recommend that I use a power steering filter, what is that? is it some sort of inline filter like a fuel filter?

I've never seen a filter with the pump. Probably the seller anticipates wear matter in the rest of the system which either would cause, or be the result of, the pump being replaced. So the addition of a filter would protect the rebuilt pump.
Is your pump good except for the leak? The tough work is in removing the pump and the pulley. Once you have that done, you can clean the pump in solvent and hopefully find the leak. Probably the big O-ring between the plastic end housing and main body, or the oil seal behind the pulley. Or maybe the O-rings at the hose fittings.

I mean, it works. It just leaks real bad now. it was just a small leak. Now, Oh my gosh! I have a small red lake under my truck. I guess I could try the kit they sell. I just thought it might be a few too many little parts for me.

eh, I suggest that the filter is a 'feel good' thing.
IMO, if the OEM didn't put one on there, it doesn't really need one as long as things are started out clean.
Suggest to get the right tools for the job, else your new pump will end up as junk, or best case, the pulley won't be in line with the rest of the serpentine belt path.
An old trick was to put some brake fluid in to swell the seal - however, it sounds like your leak may be beyond this. Plus, I think this was an old trick meant for those wanting to sell the truck - along the lines of sawdust in the axle, etc.
