Question LS power steering pump...

I'm trying to remove the power steering pressure hard line from the top of the PS pump on my LS2.
I backed off the flare nut and the line is loose as can be but it won't come out. Is there something I need to release to get the line out?

Return or supply? If it's the return, it may be one of the hard lines that have the clip in the side of the nut that you can depress and pull the line out. My returns were just hose clamp type lines. The supply was just a standard nut that held the hose on.

Hmmm..
It's the hard line... the other is just a rubber hose coming from the reservoir.
The nut came off just fine... but the hard line is still stuck inside. It's very loose and wiggles but won't come out. Hope I don't break something pulling it out.

Re: LS power steering pump...

Pretty sure there's an o-ring in there (the new fitting on the back of my pump is an o-ring inverted flare fitting. Not sure why it won't come out, but as long as you're pulling straight back on it, you shouldn't be able to hurt anything that I'm aware of. Is there a bigger nut around the one you already pulled that would back the whole fitting out of the pump?

No...
The line is just floating in the pump. I can see inside the pump.

Re: LS power steering pump...

Have you tried to give it a hard pull yet, or are you being a sissy about it?

A sissy doesn't have to buy a new PS pump.
A gorilla on the other hand....

Re: LS power steering pump...

Can't really help you on that one, but I have been doing a lot of the pull and pray method on my LS engine recently. I fought with the dipstick tube, knock sensors and the cam sensor this week.

I would try wiggling, twisting and pulling straight up on it. You could try posting on LS1tech, but it's kind of hit or miss over there.

That was kinda what I was getting at- there's a lot of o-ring seals on these engines, and they're tighter than you would expect- even things like the oil pump pickup tube (which needs to be changed along with the oil pan), the steam tubes on the intake, crank/cam sensors, etc. Makes for less leaks, though!

Re: LS power steering pump...

The oil pickup tube was a snap really.
Nothing else is coming off the engine besides the PS fitting so that I can have a new line made that points the right way. It's plumbed straight down and to the passenger side in the GTO. The steam tubing is already plumbed, as is the vacuum from the intake for various things like PB.
