I want to buy an AFPR, but when I was lookin them up, I found that they have a range only from like, 25-60 psi. The highest I've seen was 70 psi. I thought fuel pressure surpasses that amount?

I was lookin to buy this one from Summit...

Anyone have any opinions of it?

Also, with this installed I would no longer need the FMU correct? Where is the FMU located? I have the stock Stillen setup as far as I know. I bought the car with the kit so I'm not positive but, where should it be?

Thanks for the help guys.

 

Looks like you want to upgrade the fuel system like I'm doing at the moment!

I've read that the afpr's only job is to lower the fuel pressure to 34psi at idle. For some strange reason I can't lower my Aeromotive fpr below 40psi down to 34 psi @ idle and so I'm picking up an AEM brand today.

I have the BEGI fmu hooked up to the fpr. It replaces the stock Stillen fmu.

 

This FPR may not work for you. First off, this doenst have a vacuum/boost port so it will not change the fuel pressure from idle to wot. even the stock FPR has a vacuum port. Second, it doesnt even come with any mounting brackets nor any extra ports for a gauge.

IMO s quality FPR costs about $100+ depending on what brand, some people have used ebay FPRs but the one my friend bought was a POS. The one that I bought and have been working well is from Accufab. Its about $110 which is one of the cheapest one I've found.

Here's the AEM universal fpr. You can get it pretty cheap.

AEM's Universal Adjustable Fuel Pressure Regulator includes many of the features found in the AEM application-specific regulators and can be remotely mounted on ANY application that utilizes a return hose. This unit is capable of supporting enough fuel flow for engines in excess of 1000 horsepower.

Key Features:

* CNC-machined from 6061-T6 billet aluminum

* Patented interchangeable discharge ports match regulator output to output of any fuel pump

* Adjustable from 20 psi to maximum fuel pump capacity

* Remote mounting bracket and comprehensive installation instructions included

* Manufactured and assembled in the USA

 

$110>$189 that does the same thing and same quality FTW! You'll be buying AEM for the name.

 

The B&M one from Summit above is for a Honda/Acura only. You need a universal one.

 

I bought the AEM one it works good, but the accufab one works good too, and it cost 80 bucks less. that is your final awnser.

 

Awsome! haha .. thanks guys. Anyone know the location of the stock FMU? Because I'd need to replace/bypass it somehow in order to correctly use the FPR, right?

Thanks again.

its right off the end of the rear bank fuel rail. You need to buy a fitting from someone on the org (sx7?) and replace the fpr.

 

I used this as a guide to how things hook up.
