Top left goes into your air intake system. It sucks filtered air for the cold start air bypass. It can be blocked off with no real downside.

The other 2 were the coolant circuit for your throttle body. You can block them but the top one is handy for bleeding air out of the system.

Hey bro do u mind sending me a pic of how of got your fuel lines setup, fuel rail etc

I got the hybrid racing fuel linekit
Motor vehicle Hood Vehicle Automotive tire Automotive design

Hood Automotive tire Rim Motor vehicle Bicycle part


I'm no expert, I watched a video. In the first pic is my fuel filter, fuel pressure regulator and gauge. I bought a tucked (center feed) fuel system from Ktuned on jhpusa.com So I just followed the diagram they gave me. In the second pic you should see 3 lines. LEFT TO RIGHT: The biggest is your feed from the fuel pump, next to it is the return, and finally an EVAP that goes to the canister on the passenger side, I just left that one open for now.

Ok cool setup. I want to run the OEM fuel filter. I have a non tuck fuel line kit from hybrid racing. I hope it works
