On the subject of getting fuel from the tank to the IP, I think many of you are spending too much time and money on the subject.
Based on the request for a dead horse emoji, I assume the common talk about a Facet pump it is a 40223 that people are referring to. A brief look at eBay shows $60-150. For about $50 you can get a completely serviceable pump and a MUCH better filter.
It starts with chucking the filter assembly on the engine - it was put there for factory assembly reasons. Keep only the vacuum switch that lights the dirty filter light. And there will not be a return line.
Now look at this pic.

The filter on the far right is for the transmission.
To the left of that is a two micron Racor fuel filter
On the frame is a pulse pump - when not powered is is just a check valve.
To the right of the pump is a block that fuel passes thru, and has the dirty filter switch, and a valve that I use if I want some fuel in a can.
Fuel goes from the tank, thru the filter, then the pump and block, then to the IP.
When selecting a pump, it is good to have a base line. To evaluate pumps there is a bit of a chicken and egg process - you first must have a functioning system with the engine running. So we will assume you have built the above system with whatever pump you could scrounge.
Then the first pump you will test is a piece of hose. I have a three way switch, that will run the pump only when there is oil pressure, always, or never. The system is very useful for priming and maintenance.
I have reported here, that at least a couple times I have driven off with the pump off, and the engine did not seem to notice. But that was three miles, 50 mph, on flat ground.
It recently got much more extreme. The main power feed found a way to ground. The auto reset breaker was cycling. I disconnected the wire, jumped the IP valve and the starter relay and drove home. At that point the only thing with power was the IP valve. The E4OD power-off default is forth gear, no convertor lock, so acceleration was slow.
That trip was well over ten miles, and near the end is a hill that I pulled at near full power 60 mph. And my van is 9K#
And that was not thru the pulse pump but thru one of these that I had recently swapped in.

So please, let us not agonize over pumps.
