The caps have the hose nipples centered inline.
1/4 inch ID hose for late 7.3 engines (~89-94)
The caps have the hose nipples offset along the side of the cap.

The picture is from this site:
Ford diesel 6.9 7.3 IDI
There is a guy on here that has made a few sets of brass caps for our trucks, so far only the early smaller hose style I think. Do a search and they will turn up.
Just for fun, I'll add that I reused my original caps about 2 years ago when I put the turbo on (desperately needed new hose though and o-rings though). I also reused them last year when I put new injectors in, but reused the hose as it was still good. Have had no problems at all. I think unless the caps crack, they're probably still good, and supposedly the OEM ones have worked better than some of the aftermarket kits. The secret is probably good o-rings and well lubing them.
