My gut feel is that the H piece is either:
A pressure relief valve which opens if the tank pump over-sends to the secondary pump. The valve will open and the excess will flow back to the tank. Likely to prevent the tank pump over-working against the secondary pump.
or a check valve which prevents the fuel falling back towards the tank.
or some legacy setup which is capped off and just re-used from something else in the JLR product line.
To be honest, it's that broken, I would cut it open and see what's inside to figure out what it does (if anything).
As an interim, as mentioned above, replacing the sections with straight pipes is not likely ( as far as aI can tell from reading the workshop manual ) to adversely affect the working of it all.
If it helps, those connectors are SAE fuel line connectors ... it is possible to get them such that you could rig something up and still use the existing clips on the hoses that connect to the H-piece ... For example:

For the return line ( the longer left pipe in your picture of the H-piece ), you could use 2 male connectors joined with a short piece of rubber fuel pipe.
I'd imagine you could do the same for the send line, as it looks like the top-right pipe ( missing in your picture above ) is just a rubber pipe clamped onto a plastic male end ... so again, 2x male connectors might suffice.
It's certainly an approach I would try first, and could save you a ton of money. V8 or else ...
