Gm ls3/7 power steering hose/fitting problem

[68sixspeed]

I'm sure someone else must have found a fix for this, I hope... Using a 2007 ls7 with the gm front drive... I picked up an m16x1.5 to 6an adapter to screw into the pressure port on the power steering pump. That is ok, but the pulley is too close to clear the #6 an hose fitting coming from the power steering box. Help is appreciated. Thanks, Dan

I'm not sure the LS7 is the same as the LS3, but here's what I did, using a DSE relocation hard line as a starting point. I had to shorten the banjo bolt and make the banjo fitting shorter on my mill, along with move the hard line a bit, but maybe this can help:

JP, thanks, I believe it is the same between the ls2/3/7, so the pics are a big help! Thanks! Dan

(I'm open to other solutions too if anyone else has done this too!)

Edit-your idea gave me another idea to check also, I found a m16x1.5 to 6an banjo adapter on eBay, that may work as my current lines are good on length...

I used a power steering hose from a C5 Corvette. It has a special long fitting to clear the pulley. They can be purchased at Rock Auto for less than $10. Depending on your application you might have to take it to a shop to have it made longer etc.

Are you connection to a rack or steering box? I'm on the DSE steering box so I figured the length and fittings would be different?

I used Detroit Speed's power steering pump fitting that has a -6an male output to eliminate the screw in adapter. http://www.detroitspeed.com/1967-1969%20Camaro-Firebird-Products/090401-psp-otlt-fttng.html

That elliminated the hex fitting in the pump that the factory pressure hose attached to? I wasn't sure if that was pressed or screwed in...

Thx, Dan

It screws in....the pic below shows the factory fitting with the adapter on the left and the DSE fitting on the right.

Mint! Thanks, I'll order it in the morning. Dan

Ditto. I also cut the box end off and reflared with a standard fitting.

I used a PS AN fitting and had some clearance issues too.

All I did was shave the one side down a bit with a file. So far no issues and no leaks :)

BUMPING and old thread:

The OP mentions using an M16x1.5 to 6an adapter, which is like the blue fitting pictured below:

But the o-ring configuration on the DSE fitting posted by RocketRod is completely different (the O-ring is much higher on the fitting):

I'm using a GTO LS2 pump. I'm little confused as to why these two fittings (the blue fitting in the top picture and the fittings in the bottom picture) are so different from one another.

Are they not meant for the same type of M16 pressure port?

Thanks.

Most guys use this adaptor now. Turn-One has them too.

Tipsy, you are looking at two different fittings. The blue adapter threads into the adapter that is already in the pump. The DSE part replaces the adapter that is in the pump....

Use the fitting the Don linked.

Use the fitting the Don linked.I'm traveling at the moment so I don't have my pump in front of me but as far as I can recall, the LS2 GTO pump has no adapter from the factory. Or if it did, it's no longer installed in my pump. Assuming that's the case, for clarification, the blue adapter is not intended to be installed directly into the pump?

I need to fabricate a hose to route from the pump to a hydroboost unit and I'm considering my options for the cleanest installation.

I had the hose pictured below made to go from the hydrobooost to the power steering rack and would like to make a similar hose for the pump to the hydroboost.

The o-ring flare fitting you see on the hose I had made is for the connection to the hydroboost but I was under the impression I could use this same M16X1.5 o-ring type flare fitting for the pump side too, should I decide to go that route. Is this not the case?

I'm just trying to be clear on what my options are and how to make a proper connection at the pump. I will use either the adapter Don linked-to, a custom hard line with an o-ring flare similar to what's pictured below (if this is viable) or perhaps a banjo fitting.

My goal is to keep it neat and to have as few connections as possible.

Thanks!

Mea culpa. I just found this picture I took when I first bought the engine a few years ago. It's a little out of focus but it does look like there might be a factory adapter threaded into the pump.

[badazz81z28]

Yup, this is what I'm using. http://www.detroitspeed.com/Steering/090401-steering-pump-outlet-fitting.html

Stock C5/6 accessories and a standard -6 AN hose with the above fitting and no clearance issues.

AndrewI bought this but due to its height, it's going to interfere with the return hose on my LS2/GTO reservoir. I'd like to keep the reservoir where it is (stock location).

I removed a M16 banjo fitting from one of my discarded BMW power steering lines and was going to have it silver-soldered onto a new hard line. This would be the best solution because it is by far, the lowest profile. I bought a BMW M16x1.5 banjo bolt but at 28mm (measured from under the head) it's too long to fully seat in the power steering pump.

I've searched online for a shorter banjo bolt but everything I'm seeing (of the ones where the length is actually specified) are 28mm or 30mm.

I can post some pics later.

Thoughts?

[TipsyMcStagger]

I ended up having a line made with a M16X1.5mm tube-nut, like I did for the hydroboost side.

The hose shop was able to make a pretty tight bend which kept the line out of the way of the return hose nipple on the reservoir.
