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?

A good starting point is get a gauge and check. What engine modifications have been done or what injectors being used that need higher pressure?

I agree, problem is I broke off scrader port so I have it sealed with screw at the moment. Ported tpi top end, 26pd injectors

if only modifications is ported 22#hr and tuning is the best solution. Running 26#hr with an injector constant of 22#hr you will be rich. Add more fuel pressure to that doesn’t help the situation.

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.

It is tuned for those injectors

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.

if it’s tuned, than once again no need for the bandage 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.

If it’s tuned it’s tuned at 3 bar , increasing it won’t help if it’s tuned properly with datalogging, correct flow rate in constant and correct voltage offsets. Leave it backed off all the way. You complicating things if it was tuned.

george88gta

OK that's exactly what I needed to know . with the screw backed all the way out it should be stock fp?

george88gta

Thank you , btw u Wouldn't happen to know where I could get The schrader valve port would ya?

There discontinued years ago, would need a used rail

I need housing of the valve. Not the valve itself . I have actually called you about it a few weeks ago.
