Help ID this hose in my 1987 325 please

[chefmike70]

This hose goes from the valve cover
fitting seen here under the ICV

to this fitting here

It is badly dry and cracked and I hope it is the root of all my evil.
IS there a BMW part number for it? It appears to be purpose made as one end is larger than the other.

I got the new hose in and installed, car is better but not fixed. here is my continuing situation.

Car starts and runs. I let it warm up at idle. After 5-20 minutes it will die.
I have a fuel pressure gauge tee'd into the fuel line. During normal idle it is about 29 psi where my book says it should be. When it dies it is at 40psi and holding.
I can undo the fuel line and bleed the pressure off and it will restart. FPR has a new vaccum line and there is fuel in the return line but it is not under pressure so I don't think there is a blocked return line.
When the gauge is at 40 psi and the car won't start I can introduce starting fluid or fuel through the side of the intake boot by removing the ICV hose and reattaching it. The car will run for a few seconds until that fuel is spent so I know I am getting spark.

My question is: Could the electrical signal to the fuel injectors be cutting out so they are not delivering fuel? If so how do I go about diagnosing that? Since it is an ETA I don't have a c191 as that seems to be the cause in other posts I have read.

Here is what I have replaced with new so far:
CPS's
Fuel filter
vacuum lines/breather lines/intake boot
main relay
fuel pump relay

I have cleaned and checked the FPR, ICV, fuel injectors per the guidelines I have found here but they all seem fine. I do believe I need a new TPS as I don't hear a click as I believe I should- I am getting a meter today to test it to make sure.
