Well, a little wrinkle developed in this project today. I spent most of yesterday and today machining one of the adapters for the left side of the engine. In order to get one done as soon as possible I decided to do one of the versions without any of the bracket attachment points, so I could at least mock up the complete setup and check to make sure the whole assembly would bolt to the engine. Again I made a few mistakes in the programming along the way, but got a pretty usable part in the end. This week I'd also ordered one of my own CVR pumps so I didn't have to use Rob's to keep mocking things up. Late this afternoon after I got the left side adapter finished I bolted it onto the pump and then bolted the whole assembly onto the engine. Everything went together really well, and it looked pretty good:

When I ordered the water pump this week I also ordered one of the inlet tubes for the pump, so I could see how that looked in relation to the rest of the engine. I didn't like what I saw when I looked at that:

The tube, unfortunately, aims right at the fuel pump mounting pad. There is just no room to put a lower radiator hose on this tube in the position that it is in. Also, the tubes from CVR are only available for up to a 1.75" ID lower radiator hose. Most FEs take a bigger hose; my Edelbrock pump measures 2.1" for the OD of the inlet pipe, and 2.275" for the "barb" section at the very end, that the hose has to slip over. The hose size probably isn't a major problem, but the location surely is.
The CVR tube that I bought is the short version, for a 1.5" ID hose. This one could be shortened about an inch, so that the rubber radiator hose could be installed. The larger diameter version, though, won't work if you just shorten it, because the edge of the tube would be too close to the timing cover; I don't think there's any way you could get the radiator hose to slide over the tube because it would be squeezed too tight between the tube and the timing cover. Here's a picture of the CVR tube I bought, unscrewed from the water pump:

Just mulling over the alternatives, one option would be to buy some mandrel bent aluminum tubing, and weld a 30 degree bend into the middle of tube, to point the inlet away from the fuel pump mounting pad on the timing cover. Or I could try to machine one with a bend in it, which would be very complicated but probably do-able.
What do you guys think?
