Default Corvette Power-steering pump

I was trying to fid what connection I need on the powersteering:


-6 AN (16mm x 1.5 O-ring Seal) Power Steering Adapter
-6 AN (male to 5/8"-18 O-ring seal) Power Steering Adapter. Clear anodized
-6 AN (male to 11/16"-18 O-ring seal) Power Steering Adapter. Clear anodized

Witch of these will fit the outlet port of the Corvette Power-steering pump?

Its a 2008 Corvette setup, LS3 engine and accessories.

Hi!
Thanks, but there are three thread types as mentioned above that could fit, with O-Ring, and I wonder which thread will fit?
I believe that it is 16MM, but I need to confirm this.

I measured a spare pump in the garage. The high pressure side at the pump is an M16 x 1.5 o-ring. An example of the fitting for this application is:

Russell Performance
Part # 648060
Description: -6 AN (16mm x 1.5 O-ring Seal) Power Steering Adapter

Or

Earl's
Part # 991955

I found this topic when I was looking for a solution for connecting a corvette power steering pump on an LS2 swap I am doing. I am putting an LS into my 69 chevelle. I went with the factory front drive accessories for a vette. I learned that I would need an adapter made because of the clearence between the 6AN adapter and the pully on the ps pump. I visited a local aircraft / performance products store and we came up with a solution. We used a power steering hose from a 2002 Pontiac Firebird and cut off the 16mm side making it a 90 degree angle. We attached the 16mm side to a male thread (6AN) fitting. I had another pressure line made and hooked it up. This solved my problems. Just using the 6AN adapter (like the russell or earl's) did not give me enough clearence. The Firebird ps hose was $20 from Autozone (duralast part #80229) Hope this helps. (I tried to attach some pics but was having problems)

I do not have that clearance issue, I think... Looks like I can use the adapter and a straight AN-06 connector and hose, but if it don´t fit, I will try it your way. Thanks for the tip.

I just wanted to inform that I have mounted the harware on the Powerstearing pump, and I used the following:
RUS-648060 #6 TO 16MMX1.5 O-RING SEAL
RUS-620401 ENDURA HOSE END #6 STRAIGHT
RUS-632618 Russell PowerFlex Power Steering Hose

And it worked perfectly, here is a picture:

i have a little different question about the same pump. the inlet on the pump, is close to my steering box. i have a conversion vehicle with a procharger. It appears to be pressed in to the pump housing. Has anyone pulled this fitting out and replaced it with a 90 degree elbow? the tube has a 45 already, but i figure if i try to pull it out turn it and put it back in, there is a chance I will damage the tube. well, i'm kind of stuck on this issue for now, so i would greatly appreciate any help or ideas. also does anyone know where i might be able to find a pressed in 90 fitting?

Don't see how this is possible with a Corvette pump, as the pump inlet is on top between the alternator and water pump (see arrow).

right. however since i'm running a procharger the ps pump is clocked so that the inlet is at the 3 O'clock position if your standing in front of the engine. I swear i saw one that had a inlet with a 90 degree bend, i'd like some insight though before i go tearing up a perfectly good pump. has anyone pulled out this pressed fitting? how? I tried the hammer method a little to no avail. help?
