What type of ends are on the hose you had made? Are they a JIC?
I used a Weatherhead C5315X4X5 on my truck, that converts the ports in the head to a 1/4" (-4) Male JIC fitting. My X-over hose is made from 1/4" hose with -4 JIC ends on it.
You could make it out of 5/16 Hose and use the bigger -5 JIC ends on it, but i thought it was probably overkill as the feed lines are only 1/4" and that bigger hose would be harder to work with in the tight place it has to go, and I had some 1/4" hose in stock anyways.
Here are the NAPA part numbers you need
-5ORB to -4 JIC: C5315X4X5
-5ORB to -5 JIC: C5315X5
And yes, that means that the ports in the head are indeed a -5 O-Ring Boss Fitting
