Afpr
Can someone tell me the general location on their afpr set screw at correct pressure. (Southbay , screw on top)
I am currently unable to check fuel pressure. Want a good starting point. I assume right turns of screw increases pressure. Correct?

You could tee a fuel pressure gauge into the feed line on the driver's side of the engine, I suppose. But, there's no way of telling how much the screw needs to be in or out without a gauge.

Yeah it looks like I'm gonna have to buy a fuel rail just to get another shrader valve port. Can't find one to match those threads. I was just looking for what was average on everybody else's to get it around correct pressure.

Re: Afpr
I'm not sure what you mean by bandage afpr. I'm just trying to get the fuel pressure in a good range whether that be most people screwing it in 5 turns or all the way out! When I fix the port I will be able to tell I'm just looking for advice on trying to get it within range At the current moment.
