Just got the ps box pump and lines connected...

How do we properly bleed the system? and rid the air?

fill it and start up the engine and go lock to lock with the wheel it may take some time to get all the air out... keep checking the level also good luck

I heard leave the engine off, thats why i posted this, to see what others have done :)

From Vanco Power Brake Systems ...

Bleeding your new power brake system
1. Fill the power steering pump reservoir.
2. DO NOT START ENGINE! Remove coil wire and crank engine for several revolutions.
3. Check reservoir fluid level - add if necessary.
4. Repeat steps 2 and 3 until fluid level does not drop.
5. Replace coil wire and start engine. Turn steering wheel from stop to stop - twice.
6. Kill the engine and depress brake pedal four or five times to relieve accumulator pressure.
7. Check fluid level - add if necessary.
8. Start engine, turn steering wheel from stop to stop. Kill engine and check the fluid level once more.
9. IMPORTANT - If foaming occurs, wait for one hour then check fluid level - add if necessary.
10. Road test vehicle.

Put front end on Jack stands.
turn wheel lock to lock about 10 times
check fluid
turn wheel lock to lock another 10 times

repeat steps until steering feels like there is no air in lines.

So which one is right? Engine off, engine on, or that pull the coil thing??

run the engine, just don't let the pump run dry.

Fill it up, jack it up, start it and turn to the left and right 1 time and then refill and repete turning from stop to stop and refill often. Shut it off and let the air bubbles settle and check it again to see if you need to refill again. The important part is to have no load on the steering system thats way you remove the draglink or jack it.

thats what we were doing last night ...about every other time when turning full left it would squirt fluid out the top like a geyser.. kinda funny actually, but a little unsettling.

Thats just the air getting out that was under pressure and is normal.

Here lets throw this into the mix. Fill your fluid reservoir and pull 20" vacuum for a half hour. This pulls all of the air out of the system.

It is (has been) advised to do the engine off (coil disconected) to keep some idjet from firing up a dry system.
Use your own good judgement ... :flipoff2:

Ok well we figured it out.. now we got another problem.. god im so friggin frustrated I just wanna sell the thing.

When I first put my Ford together and was moving it out of my compound for the first time the power steering would come and go and fluid would blow out the top when I loaded it up. After about three days of driving it was okay, except for that high pitched whistle.

Replaced the pump with a Fenco reman unit.
Its instructions said fill the reservoir and work the steering from lock to lock and refill fluid as necesary. A noisy pump is a sign of air in the system.

So I did this, I worked the steering from lock to lock, the instructions said nothing about taking the load off the system so I was getting jerky steering back and forth. I finally gave up and jacked the truck up. Worked the steering for about an hour and it still wasnt right. Let it sit over night to hopefully let the fluid settle and the air come out.
Seemed okay fist thing in the morning, then half way to work my power steering went away, I pulled over and checked fluid, it seemed fine. Had no choice but to continue on to work with no power steering, then as I turned the last corner to get into work the power steering came back, with a vengence, it was suddenly the easiest steering I've ever experienced, holy was I impressed.
Then on the way home it went away again.

Kept happening like that for about a week. Now it seems to be pretty reliable, but I've got barely any power assist at idle speeds, kind of annoying to have to rev the engine in a parking lot get it to turn the wheels.

I'm getting my power steering box rebuilt in two weeks so I'll quiz the power steering experts about it and see if maybe theres a stronger pump available or maybe he can pressure bleed it for me, cause man I'm getting sick of lack of power steering with 38.5 swampers.

if you damage it with the engine on then the pump was bad to begin with... as long as you don't let it run dry it will not hurt it:p
