Today I was driving along happily until my car felt like it was developing a miss or flatspot
I stopped and had a look and noticed my fuel pressure reg bouncing around the 13 to 15 psi



Webers only require 3psi
Does anybody have any idea's as to why it did this?
Are they easy to pull apart?

could be dirt in the fuel blocking the reg ... as for how easy they are to pull apart, NFI, I have never had to do it

This was a topic I was going to bring up so I'll hijack this thread instead

Where is the regulator on an EF 5.0? I suffer from a rough idle and it surges slightly at the top end under full throttle. My fuel pump is a non-genuine unit which I feel may not be quite up to the job.

Anyy suggestions on how to adjust the pressure and the pros and cons of doing this?

Mike

The fuel regulator is located on the passenger side fuel rail at the rear of the intake manifold.
I would suggest that you buy an adjustable fuel regulator.

Kirban seems to be the go with the cars that I see in Muscle Mustangs mag.
That is the one that I bought but am yet to fit.

So the standard 5.0 regulator isn't adjustable?

No the stock one is set to around 38psi from memory. I have just put a Holly adjustable regulator on mine to sort out fueling problems, and it does a good job. Easy to fit and adjust all the way up to 80psi from memory, although you would never be running that pressure.

Mike, adjusting the fuel pressure is only good if you need more fuel due to fairly large modifications. Unless the fuel regulator is stuffed, you probably will not see any difference using an adjustable one, although it makes fine tuning easier.
