One thing to keep in mind is with a mechanical, all soft lines and connections need to be right on the money. If you have a dried, cracked section of rubber line, or a loose clamp, it will suck air. Depending on the routing, a soft line can also collapse under suction. And those situations would mostly happen under a demand for fuel.

Always keep bends to a minimum, and make sure they have a proper radius. (soft lines)

I remember I had an issue a long time ago with the 'bird, and the soft line that ran from the sending unit to the hard line would collapse under load. I put a zip tie on the bend where it would get sucked together to help prevent it. Finally replaced it, but took some time to diagnose.
