None of my petroleum, light oil, or heavy oil tanks are full (and even if they were i thought that only stopped the refinery from working, not the cracking process). So what's the deal?
Pictures:
My Light oil cracking producing pretroleum

Following the line up a bit, still pressurized

connection to petrolum main, not pressurized,
NOTE: The pipe-to-ground piece that connects to the main is at full pressure, but the second i hover over the main line it goes down.

You may ask why the fourth picture shows 1.6 and not 0.9 like the third, it was because my light oil tank WAS full when i took the third picture and then i added another think that it may be the problem, and my refineries started up again making petroleum which raised it to 1.6, but the pipe-to-ground connecting to it is still at 10.
Why isn't my light oil cracking working?
