I have the entire EVAP system deleted. This is how the EVAP system looks like when its installed.



This is how I'm planning to vent the gas tank.



I'm gonna cap off the port circled in red. The area circled in blue will be my vent line.

Also with the filler neck, I'm gonna cap off the unused lines which is circled in red.



Any problems with this?

 

the only problem I see is the potential that the blue line is something other than a simple tank tap... almost looks like the pressure sensor tap. Which if I remember right, has a unique sort of valve in it.
Again I'm not sure, it all depends on what that line did originally.

question: what's wrong with using the red port for the vent?


keep in mind for the filler neck, you need an air vent. If you don't when you're filling the tank it will trap air and cause the auto-shutoff to trip.
Your new vent should take care of that, but you have to be careful how you route it or you'll end up with fuel spewing from the car close to the exhaust.

 

when i blow air thru the filler neck, air comes out of both ports circled blue and red in the picture above.

here is the diagram for the evap system (02-06 rsx)



maybe i should run it like this? plug the port circled in red, and run a line near the back bumper from the port circled in blue?

do i really need the 2 lines going to the fill pipe? if i don't i can get rid of the white valve and run a line directly from the port circled in orange.

 

Bump

 

I dont have anything to add, i'm just curious why you're removing all the evap controls?
