I had a problem similar with the subject of your video but in my case it was from the priming manual pump because in it there are one way valves... and the valves didn't work properly at that time. I've changed that priming manual pump and it was ok for more than 6 months but the valves failed on the second priming pump the last thing that i've done was to buy 2 valves from the plumbing department and put those ones before the priming pump and after it. now i'm driving with this solution for more than 2 years.
Good tip using compressed air to find the leak.
thanks for sharing

How can I end bubbles in the diesel fuel filters?

[@Gothic830]

This probably can be solved with non-return valve to insert on input and output fuel line.
