On my buddies Poo Pro last year he had the same issue with the air bubbles? He figured out if you take a pin and heat it up and poke a small hole in the rubber on your oil tank cap the bubbles will all come out of the line by themselves ( All of his came out over night and never had them again) I already did this to my new Pro also, just another thing to fight the bubbles.![]()
not sure if im gettin this... cant you just remove the cap
