Saw something about it being a venturi set up. I'm wondering if the fuel was so old it somehow clogged it. I'm probably going to have to pop it open and take a look. Just figured I'd check see if anyone had dealt with something similar. Thanks

The system is constantly pulling fuel from the passenger side (that side does not have a pump) into the driver's side where there is a pump. I don't know the electrical details of the non-pump side. It's possible there are other electronics involved in the passenger side in order to pull fuel from that side, so it's possible you only drained the fuel that was already on the fuel pump side.

Update went back next day and tested again and was able to pump a few more gallons (only had two 5 gallon containers). The first night approximately 7 gallons till the pump audibly and visually was running almost dry with little surges. Second night about 2-3 gallons pumped out no issue. It seems the system may be slow to pull from the other side because of obstruction or simply how slowly it pulls naturally. Fuel was 91 over a year old as a reference. I'm hoping it was something that worked itself out by use. Going to drain last couple gallons tonight maybe add in some stabilizer or cleaner. I suppose I could experiment and add it back in and test see if I have the same issue.

Update to my experiment which probably won't really help anybody ever besides neurotic people like myself. After refilling and testing again I got the same results as the first time. I was able to pump approximately 7 gallons fairly quickly and then the pump started to run a little dry with surges of fuel. Conclusion the venturi system is too slow if you need to pump fuel into your engine at a rate of say 2 gallons per minute but should be ok below that.
Disclaimer this is in no way an actual scientific experiment and a variance of 2-3 beers should be added to all calculations, or maybe subtracted.

2 gallons a minute seems pretty steep. We can probably manage to stay below that
