I think your hoses are crossed.
Other than that, you may not have the correct pump - is it truly from a '65 - 69? The later canister pumps for the longer Ford steering box look identical, but they are not the same internally.
Or, the gearbox is snafu-ed.

yes it is from a 1965 ford mustang with a 289

A 65 Mustang PS pump operates at a different pressure than a pump for a truck with a Bendix box. Just because they look the same does not mean they are the same. Hawkrod

so this pump is not right and wont work then?thats why the wheel is doing this?

[banjopicker66]

Hawkrod is right, that is the wrong pump.
I knew the car pumps are different, but I assumed your pump was for a '65 truck.
As proof, the online stores show identical pictures, but different part numbers.
About $50 at Advance Auto for the correct one.
I would take your hoses in to make sure they will fit the correct pump.

this is getting very frustating,i cant beleive with all these trucks out there there has to be someone who uses a 302 motor with a bendex pump that make it work!

[jeffs1965]

so the hoses crossed does not sound like the answer then?

Probably not, Jeff. I was assuming your pump was from a truck Bendix power steering system.
You could try reversing the hoses at the steering box.
If you used factory hoses, they probably won't swap around because the fittings to screw into the box were sized differently. If you have a factory pressure hose, and the fittings for in/out are different on the box, then they won't swap. This would lead me to conclude it is a pump problem.
However, if the hoses are custom made, then they might indeed be backwards, so the fittings would have to be changed to test it.

[jeffs1965]

i will give it a try,i just did not want to swap hoses around if the pump is wrong anyway.

[jeffs1965]

because my hose are custom made so i can switch them around,but again if the pump is wrong it probally wont matter?

How can you cross the hoses if one is high pressure and one is not?
Do some pumps have line fittings on the low pressure side?
