A/P pump below Uflex pump...and I think both are normally below the steering wheel pump. The Uflex pump has the fill reservoir which feeds downhill to the A/P pump.
Your steering ram looks like the same one I had. In my dual outboard configuration I had to measure CC capacity x2 so it was 120 + 120 = 240 and the max spec on the type 1 pump from Raymarine was 10 CC shy of that (EDITED TO ADD SPECS BELOW). My numbers in the post above may be off but that calculation is why I went with the type 2 pump.
RAYMARINE TYPE 1 PUMP SPECS: Ram Capacity: 80cc - 230cc (4.9in3–14in3) RAYMARINE TYPE 2 PUMP SPECS: Ram Capacity: 230cc – 350cc (14in3–21in3)

Thank you again. This information is helping a lot. My concern now is the power steering pump if the AP pump has to be below this. My power steering pump is in my console below the helm next to the batteries. Batteries need to come out to access which I already know is a PIA since I replaced them last summer. I was planning to put the pump in my foot locker below the helm. Have to check the difference in height, but almost certain it is above the pump. Would have to measure by how much. Not sure if there is any other spot to put it.
I have the UFLEX UC128-SVS 2. Quick search shows this is volume of 120 cc - 7.3 cu. in.
Leaning towards the 2.0L pump.
Pics below of where the power steering pump is and where I am planning to put the AP pump. Would have to cut some access for the hydraulic lines.
Edit: Maybe I'm looking at this wrong. The AP pump needs to be below the helm itself? or the power steering pump?
You might want to email Uflex. I was told by Uflex it just had to be below the helm, not the Uflex pump. I would be unable to get it lower than my Uflex pump and I have seen other installs where the AP is higher and it works. But again, I would verify with the tech support at Uflex USA. They are very good. The Uflex pump hydraulic lines on my boat feed right into the helm and then the helm goes to the steering cylinder. See the attached pic, I have T'ed into lines indicated by #7. I can see if the Uflex pump went to the steering cylinder why the height might be important relative to the pump, but do not see why in this case where the Uflex lines run only to the helm and are not T'ed at all. I am not sure the model Uflex I have but I do have a Verado 300 and used the 1.2 L pump. You could also ask them or call Garmin. Attachments:

Call Garmin to verify pump size, you should not require a 2.0 pump, that size is usually reserved for twin cylinder steering systems with more fluid. Again, bigger is not better in this case

The maunal for the Ultraflex Power Steering page 30 has NOTES FOR AUTOPILOT CONNECTION--the autopilot pump has to be below the Uflex pump, so I disagree with the advice above on that point. That part is clear. I agree your pump size for a single outboard is likely the smaller pump but good to confirm that with Garmin. If you have dual engines, do the calculations I did. I agree it's worth a chat with Uflex for planning your autopilot interface to the Uflex power steering pump. My installer provided standard hydraulic steering hoses that come in various lengths...we used a couple of 4 footers and one 12 footer (only needed 10 feet but the one in stock was 12). They come in pairs so I had an extra 12 footer that I gave to the installer. You can also get custom made hoses but the price difference to buying a paired of pre-cut lines is probably a wash or even more expensive than just buying pairs in the length you need and having one left over. Below is an email from Uflex Tech support guy, Scott Hodges that I got after discussing my install with him: Hello Jerry, Per our phone conversation, here is a bit of instruction for your autopilot install. Four lines on the MasterDrive helm; P-pressure, T-tank, L-left (port), R-right(starboard). Remove the L and R from the back of the helm, attach them to the t-fitting you install on the valve body of the autopilot pump. Buy short hoses to attach to the other side of the t-fittings on the autopilot and replace them on the L and R location of the helm. Return for the autopilot will attach to the t-fitting on the MasterDrive pump (T location) Any questions, please feel free to contact me here or at the numbers below. Thank you very much and Have a great day, Scott Technical Support (tech@uflexusa.com) shodges@uflexusa.com 941.782.1877 Direct Uflex USA Inc. 6442 Parkland Drive Sarasota, Florida 34243 Main 941.351.2628 Fax 941.360.9171 www.uflexusa.comAttachments:

I definitely agree with Jerry on what the instructions say, which is why I also said to contact Uflex. In my specific case, I was told by them it just have to be below the helm. If you can located it below the Uflex pump, then do it - I would have. And I do want to be clear that make sure you get verification as I am explaining what I did. For the record, my Uflex pump feeds UP to the helm only....everything from there is downhill. It does not feed directly to the AP pump ever without going through the helm.
This was their response (my original email indicated that the AP pump would not be below the Uflex pump but below the helm):

Yes you can put the auto pilot near the helm. Use t fittings at the auto pilot pump. Disconnect the port and starboard lines from the helm and connect them to the t fittings at the auto pilot pump. You will have to buy two hoses to go from the other side of the t back to the helm. The return line is a low pressure hose and that can be cut for you to make it work. The system will need to be rebled and the auto pilot will have to be purged also.

Ok. I will definitely give Uflex a call and Garmin. My space is tight behind the console and below where the batteries and power steering pump is. Lot of stuff already added in there. spent some time staring at it today. If the the AP pump must be below the power steering pump this may put an end to it. No way I am moving the power steering pump. No where to go. May need to remove my fishfinder black box, 3 batteries, and cut some ties holding everything together to see what I am working with for the hydraulic lines. tough to see where they are all going right now. Thanks again and at least have a better direction to go and questions to ask.

You can see my finished install in this post: sailfishownersforum.proboards.com/thread/2973/autopilot-install-completedMake sure you have room to connect a hydraulic hose to the UltraFlex T connection as that will be needed. For my install I had room to do it but had to relocate the Ultraflex pump very slightly and change it's angle so that we could get the hose on. I don't have a photo of that but can get it if you want to see it. My Ultraflex pump is on deck level and the A/P pump is in front of the helm in an area that goes a bit lower than deck so it made for a good place to put it.
