I did a lot of research on different sandwich oil filter adapters. They are not all created equally. You want to make sure you are running the pump pressurized oil through the oil filter before it goes into the engine. I planned to install a manual oil pressure gauge in the output port on the adapter, but you could just plug it off. Depending on which oil filter your engine takes (metric or SAE) you would have to purchase the corresponding sandwich adapter. My truck uses the metric (Motorcraft FL820s) oil filter.
Below is a link to the metric sandwich adapter I planned to use. I believe David made his own using a 3D printer.

The pump David used (and that I was planning to use) was sold on Amazon and was made by Amarine. The price fluctuates, but was typically around $80.
I have links to various parts I planned to use and I can post them, but they've already been posted here multiple times.
You would need a switch to run the pump before starting your engine. I planned to use a momentary dash-mounted switch, but IIRC David used a hand-held remote to run the pump.
One of the biggest problems is that there's no room under the hood to mount the pump. David relocated his battery to the bed of his ST and mounted the pump where the battery used to live.
As David had done, I planned to replace my oil pan drain plug with a banjo bolt fitting. Then run a hose through a small in-line filter to the pump, then from the pump to the sandwich adapter. A check valve is also needed to prevent oil from being pushed back through the pump once the engine is started.
Here's a link for the Amarine pump, currently $66.99 U.S.
