does anybody know if i splice the vaccum line that goes to my gauge, and manifold, and hook that up to the vaccum ine port on the regulator

You should probably retain the stock vacuum line location, in the back of the intake manifold.

Most likely, you'll want to listen to the others, both in their insults and line location advice. Side goes to the adapter plate/fuel rail, the other side goes to a gauge (if you want), and the bottom goes back to the tank, aka the hardline.

Was there any indication that your stock fuel pressure regulator was bad? I'm still really confused as to how an ebay unit with questionable fittings and lines is more reliable/easier than just spending $5 on high pressure fuel line.

Put your tools down and back away from the car, slowly.

^ Best advice in this whole thread.

But you can't take good advice, can you? I gave you a solid recommendation in the other thread that will take you down the path to glory:

1. Stop posting
2. Read "Maximum Boost"
3. ???
4. Profit

The money you paid for your dubious eBay FPR probably could have paid for the book. I know, you are a modern man and can't be bothered to do things like read or use punctuation properly. After all, reading and books are for fags, amirite? :facepalm:

Believe it or not I'm trying to help you here. If you keep posting threads like this and ignore the people who are trying to help you will find your stay here at MiataTurbo to be very short and highly frustrating. Put down the Rockstar, pull your pants up, step back from the keyboard and try reading a book.

I hate you guys with you quirky little insults and BS. But I realized that i don't need this fuel pressure regulator.

Im going to sell it, luckily i got all of the AN fittings mocked up and connected properly to the hose, I also forked out 20 bucks for an mazda miata fuel rail adapter, so im in this thing 100$

I will try and sell it on ebay as a mazda miata AFPR kit for Naturally aspirated engines with a stock ECU (trying to get more fuel)

If you're going to buy an Ebay fuel pressure regulator, do it right and get the $25 shipped directly from China one.

Not the one that you pay as much as you'd pay for a good used Aeromotive.

Do what i do.

Ok. im not sure if you guys are realizing what i am pointing out here in my question.
BTW probably going to sell the kit as a ready to go kit for a guy with a stock miata or whatever because i have already fitted the hoses and cut them to length before hand.

But nevertheless,

The stock regulator has only two ports which the only two fuel hoses connect; the other port, is connected to the rail.
- with the adapter there is another hose involved.
So, this other hose is going to the rail. its connected to one side of the regulator this is an sending line,
the Fuel sending line that was already in the engine bay, hooked up to the top of the reg, (is this supposed to be on the other side of the reg?(an inlet as well?))

So the two inlets, one of the inlets is sending...
and the bottom port is the fuel return? Just take a second to think about that, is that the correct way.

And is the vaccum port constantly going to be connected to the manifold, or vaccum line going to the megasquirt? constantly? this is supposed to be for more or less fuel because of the ratio of pressure.

this is for purposes of sellling/helping my friend install it on a stock miata with some less mild mods

No not constantly, you connect and unconnected the vacuum line as you drive. Really quickly.

What in the hell?

I have to admit, I'm slightly impressed.

I never realized someone could make installing a FPR so hard.

:rofl:

Oh, I get it! Its like PWM for your FPR?

The NA8 even has the solenoid in the vac line already to make this happen. :idea:
