In either case, the output hose is the issue, the hose between the check valve and pump is always full and waiting, the output hose however is not.. So it need to be refilled somewhat. My injector is on the bottom of my motor, the fluid will leak out to some degree. A larger hose will need more volume refilled before sparying.
A larger hose between the check valve and the pump will hold pressure and more of it. It will act like a tank until the pump is at full power. Plus its all physics with diameter and resistance. It is easier to have water flow through a certain size pipe than a smaller one.
