What to do if Graco Paint Sprayer is difficult to prime?
If your Graco paint sprayer is difficult to prime, here are a few things to check. Make sure there's no air in the pump or hose by checking and tightening all fluid connections, and reduce engine speed to cycle the pump as slowly as possible during priming. Inspect the intake valve for leaks and clean it, ensuring the ball seat isn't nicked or worn and that the ball seats well before reassembling the valve. If the pump packings are worn, replace them. If the paint is too thick, thin it according to the supplier’s recommendations. Finally, ensure the engine speed isn't too high by decreasing the throttle setting before priming the pump.
