Well it looks like the air bubbles are coming from the super cheapo pre-filter o-ring setup, so I'm just gonna get an inline filter and bypass it entirely. So that will bypass the fuel heater and the pre-filter, both huge weak points for air intrusion. Just need to figure out how I'm gonna flap the fuel hose to the plastic fuel line/clips. I'm then going to run an engine flush with Liqui Moly Engine Flush to see if it quiets down the noise, and run Luqui Moly 5W-40. I also noticed I have an injector that is leaking there the 2 piece injector housing screws into each other.......rabbit holes I tell you!! (its a very very slow leak, just a small puddle in the injector cup after a month)
