I have found if you use a short section of 1/4" hose ( 8-10' is good ) called a whip and put your regulator between it and the feed hose which should be 5/16" and not longer than 25', if longer then the feed hose should be 3/8". This prevents the pressure drop (serge) at the gun. A small gun regulator will work also, I use both, the one at the gun is great for quick pressure changes if you change the spray fan while painting.
