Low Oil Pressure and Changing an Oil Pump | 92 Silverado

This 1992 4x4 silverado GMT400 had low oil pressure so I put an oil pump in it and improved it but it isn't what it should be. Don't know what else could be wrong with it but if it becomes a problem there will be an update. This is not a "how to" I am just documenting my work.
Like a Rock.
