That's right, my bad!I'm sorry, but that's not what it says. It says. "Install the reservoir bulkhead with 1-2 ft leading to the pump." It does not say 1-2 ft "above" the pump. I questioned the reason for this myself in a previous thread.
Many members here have successful installations with only a couple of inches height difference, and many have less than a foot of tubing between. I have 10" between reservoir & pump, and 2" height difference, and it's been working flawlessly since December—even with several power outages and system drainings.
Lindasjackson, what I'm seeing in your latest pics is that the tubing appears to be entering the bulkhead at an angle rather than straight in(?) If so, this is one possible reason for the leak—the collet can't make a good seal with the tube.

I also want to note that these tubes aren't made to NASA specifications.
