Yes,
This works like a champ and is easy and fast, it took less than 10 minutes for 5 quarts to be distributed through the oil galleries.
You pressurize the tank to about 20psi after adding the oil to it.
In the picture, for the inlet, I have a brass cross fitting with my air input coming in to it through a gate valve , pressure release on other side, guage on top and pipe nipple on bottom down to the tank. The tank I drilled and tapped for npt pipe nipple.
At the other end I have a brass T fitting attached to the tank at the bottom of the T with a nipple like before, but I have soldered into the nipple a piece of copper tubing reaching down to 1/4" of the bottom of the tank. I have a plug on the top of the T, and then on the side an outlet to the engine with another gate valve and a piece of stainless screen from a washing machine fitting in the opening to trap any stuff from the tank.
From this gate valve I ran rubber line to a T fitting that I can insert at the union of the oil pressure line, which is near the starter on the 230.
WIthin 5 minutes 5 quarts of oil were distributed through the engine.
You pressurize the tank to about 20psi.
You can watch your trucks oil pressure guage come right up and stay as the oil is flowing into the engine.
The only thing I need to modify now is to bolster the area around the holes in the tank with a welded in thick washer tapped the same to strengthen the job.
Also you have to tap the (brake line type) T you use to plumb into the oil pressure guage line. That is because the brake stuff is SAE, and the hose barb fitting is npt.
