Does it work correctly? If it does--NICE.

You could install an analog gauge in-line, to verify pressure once that sender unit fritzes-out.
Can you post a parts list for us?

Looks good. Is the hose rated for the high temperature of the oil?
Once when I was trying to diagnose low oil pressure on my 4.3 Silverado, I hooked up a pressure gauge, which concluded that I did have oil pressure. I don't remember what happened but I shut the hood and forgot about (probably got distracted?) I drove with the gauge in the engine bay for a good 2 weeks, in the summer heat. I'm glad the hose didn't burst because of the hot oil. That would have been really bad.

Well....the oil ain't hot. Not flowing. Just the ambient heat under the hood. Nary a problem and my oil pressure reads good. I will have to look up some receipts (if I can find them) for the parts for this. Note that the engine was out when we put this on. Pretty easy to get to then..ha ha.
What do you mean, "The oil ain't hot". The hot oil has to hit the sender to give a pressure reading, inside the hose to the sender, after the engine gets hot.

Seems to me oil is not flowing through the hose but more or less sitting in the same spot as the day it was installed near the sender. At the block i can see the connection being 200ish degrees from heat transfer.
Are you saying with a hot engine, the hose does not get warm/hot? If you remove that hose at the back of engine and start that engine, it is gonna flow oil.
