    Did the job perfectly. I set the psi for 55 and it holds exactly there and matches with boost.Edit: Lasted 1000 miles and failed... unfortunate that I spend the extra money on something and still can't get it to last.EDIT: i emailed the company describing my problems. I got a call but was at work, but the gentleman left an excellent voicemail with steps to diagnose the issue. Turns out my brand new fuel pump i out in a few thousand miles ago was the culprit... I stand by the product now with confidence...

    4.0 out of 5 stars Misleading fitting description
    Reviewed in the United States on June 26, 2015
    Verified Purchase
    This is a great little FPR. It is well made and should last a long time. I am using it in a carb to fuel injection with turbo project I'm doing. I will add that the description is a little misleading here on amazon. The FPR does not have -6 AN fittings, it has -6 ORB fittings. There is a difference. You can't just screw AN fittings into it, you will need an ORB to AN adapter. The description says -6 AN at the beginning and -6 ORB towards the end. Make sure you get the right fittings to screw into this thing.

    5.0 out of 5 stars When getting a FPR choosing Aeromotive is a no brainer
    Reviewed in the United States on March 22, 2016
    Verified Purchase
    Quality product. Never failed me. This isn't the first time I'm using one of these on a vehicle too. I usually try to save a buck when I can and don't shy from using generic chinese parts but when it comes to the FPR I didn't want to risk wasting time so I continue to use and rely on Aeromotive. It's a shame how fake ones are going around on eBay though.
