I am trying to get my 1.8 timed and idling right via another thread but am noticing something else that I am unsure of. In looking at the clear plastic fuel line that the return hose from the pressure reg hooks to, I can see air bubbles moving. The supply side is bubble free. How the heck are air bubbles getting in the system in between the supply side and the pressure regulator to return side?
Bad pressure regulator somehow? I have no gas leaking or smell.
