3 Lines on Power Steering Pump?

[b2948kevin]

Hey guys, I am currently upgrading to power steering on my 66 long step, and I have everything in (pics and write up to come soon on my build thread), but I am confused about what to do with the lines. I have one port for high pressure coming out of the back of the pump, and 2 low pressure nipples also. The pump and brackets came with my engine, a 350 one piece rear main, not sure of the year. Can I just plug one of these?

Here's a pic of the pump that I'm dealing with:

That spare return port is used for a power steering cooling line or a return line from a hydro booster. Yes you can cap it off.

Thanks 66farmer! That's what I suspected, but good to have a confirmation.

One last question - Anyone know which of the 2 low pressure nipples I can just cap off?

Attaching a picture for ease of viewing.

Either one will do.
Both go into the reservoir.

I agree, they are both return lines, so plug which ever one does not fit your configuration. Typically the one on the side is the return from the hydroboost.

Thanks for the replies, all! I'll take a look tomorrow and plug one off. I should have power steering as soon as I can get some time with a welder!
