Fuel Pressure Reg.

[MX3-Life]

1994 Mazda MX3

Basicly i need a new one so i decided to find the old one


Then i followed the cords to a little device some sort of sensor that has an electrical sensor plug and 3 tube connects
1 going to the Fuel Pressure Reg
1 going to somewhere near the Throttle
1 i assume was in my air box


Now when i removed my air box and put in a CAI i unplugged alot of stuff. Then i took a look at my old air box and i found a little whole that matches the diameter of the tube. So i was wondering if this tube was important and what it did?

Thanks.

Basicly i just cant seem to understand if it did go in my Air Box then what does it have to do with Fuel Pressure and a Sensor if i have a MAF... Little Parts confuse me..

I wondered about this too...you can't just unplug the wires to it, because it throws a CEL, but you can delete the vacuum lines that go to it though...it is some sort of ecu thing that controls fuel pressure a bit, but not needed though..

just put a vacuum line from the intake to the fuel pressure regulator.

there should be a nipple near the FPR to use.

I figure its a Mini-MAF but w/e ill just stick it in the intake just to be safe. Thanks... But the real problem is i have the stock rubber intake hose but a aftermarket Filter. And i still have the little rubber hose from the Regulator Sensor thingy but the thing is putting it in my Intake... Any Ideas?
(Drill a Hole? lol)

I give you my answer to a custom 1hour job *a little big* Stock/Aftermarket Fused Togethor

I call it the 'Stock Market' Intake System
(Patent Pending...)

wow, that's a lot of work to hook up a sensor that doesn't do anything

but nice ingenuity though...I give ya credit for that.

Holy
If you can do that, why didn't you just make a CAI and tap into it?










Good luck with patenting the Stock Market...

But whatever works for ya. Still does the trick!

I am stealing this pic to ask a question ... which of the 5 wires connected to the MAF sends the temperature to the ECU ??

why did you want to keep the intakes "resonator tube thingy" so bad?

yeah it looks like you could have 2 CAI's lol

cap it off with a band clip and a paintcan top.
