FUel Pressure Regulator
 

Okay.
So I'm really confused right now.
The more I search, the more I'm confused.

So I'm running a 1.6 motor and I have a 255 pump with 550cc RX7 injectors.
Now, I need an FPR, but I know my Nissans and they have the return style fuel systems.
Now, If I understand correctly, my NA6 is a returnless system?


So My issue is finding which FPR to use.
I used to use the Aeromotive on my Nissans previously.

So if anyone could direct me to a recommended FPR by the miata community It'd be greatly appreciated since I'm just getting more and more confused the more I search.

Thanks.

After actually looking at my rail and some more research.
The NA6 is a RETURN style.

So now I just wouldn't mind some suggestions on an FPR.

I'm looking at a few Fuel Labs ones and Aeromotive.

I've used both Fuelab and Aeromotive.

Which one looks prettier to you?

I had a fuelab 51502 on my Escort, Aeromotive 13109 on the MX6.

Whichever one i use on my NB will be determined by which one i can get cheapest at that point in time.

I went with the Aeromotive.

I'll just have to buy fittings locally somewhere later as they never come with fittings.
Thanks.

Just out of curiosity, why such a huge fuel pump? A walbro 190 will easily supply those injectors and will work fine with the stock fuel pressure regulator mounted on the back of the rail.

Honestly due to my Nissan experience.
After I bought the pump I looked into it and saw that a 190 would of been fine.
At this point since my motor randomly leaned out and blew, I just wanted a new pump, FPR, filters, injectors, and what not.
But I just bought the 255 with my knowledge of my Nissans.

SO yeah....
