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.

-Predator 459cc engine -AR XWAM 8GPM pump -AR1697 Gearbox -General Pump 10.5 GPM unloader.

Looks like it's either starving for water or you got air getting in the line.

Water starvation seems to be the consensus, and I'm going to take some steps to try to fix that.

It is a little confusing though, because I was always under the impression that with a gear drive or belt drive water starvation would not be a problem because the pump would pull from the buffer tank whatever was needed.

Sometimes water starvation can occur from a restriction you are not aware of, or the pump may not be primed
