Anywhere fuel could leak out is a point where air could get in. It's clear you have some sort of leak in that area so it's a good place to start.

Also, it would be prudent to check the overhead again. There's always a chance that a mistake last time could have caused the problem you currently face.

What would be the easiest way to rotate the tank to pull out the pickup tube if need be?

The overhead was done by a shop since I don’t have experience doing it and honestly I don’t have an idea how good of a job they did.Should I take it to another shop and have it redone? Like Cummins,or the bigger dealerships.
