can any of the AEM fuel pressure regulators be used for the 4 bar ECU. Or do we have to use the Universal FPR. I found a good deal on but its not the universal one. According to AEM the ratings are the same its just some are direct replacements.

I was just wondering if anyone knows that they work the same or not. TIA

I believe David De Anda is using an AEM FPR. The only requirements you need when looking for an aftermarket FPR,is that it is adjustable up to at least 70 psi! The Aeromotive is adjustable to 70 psi and the SX is adjustable to 90 psi. I am pretty sure the AEM is able to support 70 psi!
