hydroboost/pump question?

[teqoso]

I need to modify my steering pump system to put on a another return line o the pump for the hydroboost system. My question is, I am running BC Broncos heavy duty pump and have been real happy with the pump. I also do not want to go thru another pump and mounting system. Can I just drill and tap another return line onto the pumps neck, just above the mechanism. Is the possible or should I just break down and convert to saginaw?

I would start with a nice large fullflowing "T" in the return line right at the pump. Some people have problems with it others including myself don't. Then the second best would be to drill and tap an extra hole in your nice pump since it works so well for you.
After all that then you might want to convert to a different pump. But since you are happy with the pump you have now, why change it?

the problem I'm having is that the pedal returns slowly, and I understand that that means I have a little air still in the system. That I know how to take care of, I'm figuring that the pump makes a little more noise during braking. A buddy has the same setup with two return lines at the pump and he hasn't had any problems. I'll try to tap the line and see what that does for me. Thanks

There was just a trouble shooting thread on this a couple of weeks ago, the conclusion being that you wanted the return as close to, if not in, the reservoir. Any residual pressure in the steering return line would cause pboblems with the hydro unit. Just got one and I'm going to weld a second return line into the ham reservoir. Seemed like a good way.

You can tap and braze a return right to the pump. Be careful not to get really hot so you don't to destroy the seal. I'm one of the guys who couldn't use a tee in the line. I wasted 25.00 in JIC fittings to ultimately only need one weld on JIC fitting 2.00.

Good luck, Joe

For starters, the pump BC Broncos sells *is* a Saginaw pump. Cardone (the rebuilder) just puts a longer, smaller diameter shaft in a Saginaw pump body so it will work with a Ford pulley on a Ford bracket. The reservoir on that pump is also a standard Saginaw model on certain 60's and 70's vehicles.

Pull the pump, unscrew the pressure fitting and the one or two bolts holding the reservoir on. Now you can tap the reservoir off the pump body with a soft hammer. Braze or weld on a second return fitting at a convenient location. I did exactly that with my canned ham style reservoir. I had a spare canned ham reservoir in my scrap heap, so I cut the return tube out of it with a hole saw and welded it to the one I'm using in my Bronco.

You may still have a slow pedal return after that, at least for a while. It took about 2 weeks of driving mine around after the above mod before it felt right.

First of, Chucks pump is a Saginaw pump.
Second, sometimes the T method works sometimes it does not.
Third If your pump is the standard configuration pump, probably is, go to the Upull yard and get a dual return can. Any diesel ch**y pickup should have one. Get the whole pump, but all you need is the can.
Get a seal kit from the auto parts store, put the dual return can on your pump using the new seals in the kit.

Follow the bleed instructions for a new installation RELIGIOUSLY, and things should get fixed real quick.
Learned the hard way about this one, in my install the T install worked but not well. Got the can off a diesel pickup, made the change big difference.

Thanks guys I will definetly try some of the options available to me. A buddy of mine has the saginaw pump with two retun lines he can give me. Thanks again for your input.
