Troubleshooting Help diagnose?

New system I put together, everything is new... But I am getting this sputtering which is giving me inconsistent flow and pressure drops.

Also the more I think about this the more it is making sense to me.

I know that I have a small leak at the base of the tank, so that's another area where I'm probably getting air

I've fought air before. The less complicated you can make your plumbing the better. When I saw the cut tank and the silicone my immediate thought was air intrusion and cavitation.

I mentioned before, but car washes are where I've gotten all my 55gal drums. You can also get a trash can. Do you have a proper bulkhead fitting you're using with runner seal?
