get rid of the fuel pre heater. get a spin on filter housing or a filter with out the preheater. replace your in and out lines with transparent polyurethane. get rid of your water seperator.
hasn't had a preheater on it since I got it, if not ever.

That T on the fuel filter - thats the preheat fuel filter set-up.
An 85-87 Jetta/Golf Diesel fuel filter eliminates that T.
Or maybe thats what you did ?The simplest and most common things i find are the injector jumper hoses having a compromise - and/or the end cap plug on #1 injector.
About $5 puts it all back new.
After that -
Transparent fuel lines before and after filter, and the fuel return line, along with a MityVac tool - you can always pinpoint what area is compromised.
A small low psi diesel rated fuel pusher pump near tank can overcome most prime problems when all else fails. $15-25 on eBay. Also can extend the life or improve operation of a dying Inj Pump.
How does that Tee preheat? there is no externall power going to it?
I just dont understand where the fuel is going if I have the lines both blocked?
might just hide the problem untill after startup? if the input for the IP is leaking into your timing cover it wouldnt appear to be leaking from the IP but will kill your timing belt quick too
Right, just to be clear, you have half of the clear lines that you need for diagnosis of the issue and they are showing that the issue isn't on the supply side. Regardless, you're going to swap out the lines on the supply side this weekend. If it were me, I'd focus my attentions differently.
When you first start it up and look at the return does a bunch of air/foam come pouring out of the pump on the return side?
another quick solution might be a check valve between ip and fuel filter.
Seems like you replaced a lot of parts unnecessarily.
The story of a mechanics life I say. Live and learn to do better?
Check valve? How about this one.

A wee bit spendy.

That check valve would work but you have to put some adapters in to fit the VW IDI hoses. Why not buy the VW check valves with the correct size barbs? There's one on the fuel sender and one on the water separator under the car on some model years. These check valves are also on most TDI's

What cars have a water separator under the car? Or did you mean under the car near the water separator? Also which ones have the check valve in the tank? Having a couple of these in the tool box would be a great troubleshooting aid.
