Fuel Pressure Sensor Purpose?
I take it the little sensor mounted on the Stock Air Intake Pipe is the Fuel/Vapor Pressure Sensor? Is it vital for normal engine operation? I wanna move it out of sight and just wondered if changing the piping lengths will effect it? Does the pipe that leads back to the Intake Manifold have to be connected or is it just for emmision control?
Thanks for helping out with all the small questions guys!

Take a photo of what you are talking about. Any length change will affect your AFR and performance.

That is the purge valve for the evaporative emissions system. Changing the hose length would not affect it.
