I looked at it today and the fuel goes from the tank to the manual switch to go between tanks to the sedimenter to the primer pump to the main filter to the injection pump. Don't know if that's problematic that it goes that way. Today the line that goes from the manual switch to the sedimenter was visibly damp from fuel and I saw tiny air bubbles coming from it. The line was being stressed from the angle to go down to the sedimenter from the switch and I assume over time and with the nipple putting pressure and the clamp there, it created a tiny hole. I replaced that line, figuring it was a no-brainer. That apparently wasn't the only problem, though, because I'm still getting A LOT of air in the line when I bleed it. When I went to pour fuel back into the tank, the tank definitely had built up air pressure that was released when I opened the cap. I'm including pics of the line from the tank to the manual switch just because (in reverse order of that).I mentioned the (unlikely) case of having a vacuum in the tank. An easy test for that is to leave the fuel cap off so air can get in easily.
Ive had my own drama yesterday of air in the lines from a faulty hand primer/filter head. At the moment I have by passed the primary filter and I am using only the pre filter.
I diagnosed it with clear PVC hose
When I can get a video uploaded I will show you just how much air it can take before it stalls.
When the air is entering in the fuel lines it moves around a fair bit,it doesn't stay still like you described.
