Re: Fuel regulator question
Correct. It's a vent to atmospheric pressure. The yellow "cap" that is over it just helps keep the port from getting clogged with dirt by necking down the inlet. When a turbo is installed, a line is attached to this port (don't know if it is vaccuum or pressure) in order to boost fuel pressure (like stated already). Before I knew any better, I capped it off and the rig ran like shit. Ran rich as I was running at about 4k in altitude. Removed my homemade cap and it ran correct again.
