Ight so this thing is kinda like an oil pump idk i was bored
Controls
W/S - Open and close main valves (Orange)
E/D - Toggle on and off pumps (Don't hold the button the pumps are on toggle swtiches)
O/L - Pour Oil (Hold down the buttons)
I tried color coding some stuff in here so heres the colors
Red - Check Valves, these keep oil from flowing back in the system instead of the intended direction
Yellow/Green - PSI Guage, if you zoom in on it in the top right corner you will see some numbers, they are color coded to what they should be, 20, 30, and 40 are good, 0 and 50 are bad.
Orange - Starter valves, these open to let oil out of the tank and into the system
Thats about it you can do anything with the system really you can put stuff in it to see if the Guage changes or if the system clogs and if you want you can even glue the check valve into a closed position and cut up the guage and make it expload oil everywhere

Have Fun I worked hard on this!
