Default Aeromotive Adjustable FPR

Okay, I think I am finally going to ditch my stock FPR and get the Aeromotive Adjustable FPR for $149.00 at a local shop. To my understanding, all I would need to do is get two barb fittings and connect both lines off my rails (parallel) to the FPR.

Is anyone here using this particular setup? If so, please let me know how you like it or perhaps throw out some advice. Thanks.

How is your rising rate FPR anything like the aeromotive adjustable FPR?

You will need a special fitting to adapt the hose off of the stock fuel rail. If you look at the stock FPR, you will see that it screws into a flange on the end of the fuel rail.

Any particular reason you want to ditch the stock FPR?

When I did my parallel lines, I had to hack that bracket off anyways and relocate it. I have an adapter on that flange with a barb fitting on it that will allow another input. I have two fuel lines running into my FPR right now. Both are rubber fuel injection line. With a couple barb fittings that screw into the FPR, this thing should go right in.

I suspect that with the 440 cc injectors and the WRX fuel pump, the stock fuel pressure regulator is getting a major workout at idle. I can actually hear air hissing out of the FPR and I have no clue how or why.

It would also be nice to have a little more control of the fuel pressure. The 1/8 npt for a gauge wouldn't hurt either.

This hissing would indicate a leak in the vacuum side of it, with the vacuum line form the manifold.

In our case, it would be as easy as putting hose barbs on the FPR and putting it in line, yes. Though you have to be aware that the fittings that go into the FPR need to be o-ring seated, as they are not tapered thread, nor do AN fittings bottom out in them. They sell special fittings just for that purpose.

I have replaced that hose twice now and the hissing is still there so I do believe it's the dry side of the FPR... still an issue regardless...

Thanks for the info on the barb fittings. I'll be sure to add Orings to my Christmas list.

Well, the fittings on the unit are AN fittings with o-rings on them specifically. Kinda strange, it goes against what an AN fitting really is, yet they still call it AN. *shrug*

Kinda like this:
