LQ4 into a 3rd Gen/1972 Nova by frojoe

I plan to have 2 Hydramats, one on each side of the tank. To connect two mats to two pumps, I'm going to try an X-shape junction block, with two ports on one side sucking from L & R mats, and the remaining two ports on the other side of the block feeding the two pumps. My thinking behind this is that: one or both pumps can suck from one or both Hydramats, depending on fuel level and sloshing conditions.

The "crossover" part in the middle of the X is not a circle but an oval, designed to not be a choke point. The tap-drill size for 1/4" NPT thread is 7/16", so the drilled holes are offset such that the width of the center will produce a cross-section that is about 10% larger than a pair or 3/8".. so no throttling should occur.

Here is the "more or less direct" path of fuel flow...
