Default Fuel Pressure Regulator Bad?

My fuel pressure has been increasing on my car the last few weeks. Today it was at 52lbs. hose off or on. Could it be the stock regulator or maybe a leak inside the the lower in the lifter valley. I have used a whole can of carb cleaner looking for vacuum leaks and found nothing.

Seems like a rather strange problem, haven't really heard of it before. You could definitely try a adjustable fuel regulator and see if it works. They are pretty inexpensive. Kind of a bitch to put on a fox though.

I would definitely try that then. They are always useful for when you get more modifications anyways.

Maybe it is. I was running an fmu that could have messed it up somehow I guess.
I thought about pressurizing the manifold to about 10psi just to see if it would hold.
