Looks cool but will not seal on anything but the factory fuel rail, I have tried 2 different AEM rails and a golden eagle fuel rail and it just pisses fuel. Dosnt matter if you change the oring to oem or aftermarket fuel rated oring still leaks. Would not recommend for aftermarket fuel rail.

This FPR is trash. I’m on my third one and they’ve all started to leak within a few weeks. I’d rather not turn my car into a rolling ball of flames AEM. I’m very disappointed in this product. I expect better.

Installed it on my oem fuel rail, and also installed a fuel gauge, out the box the fuel pressure was low but was really easy to raise up the pressure to the recommended 50psi, haven’t had any problems

This AEM fuel pressure regulator worked perfectly for my Integra with a B20b swap. I tried the cheaper alternative first from DNA-motoring. The adjustments were very touchy. And the diaphragm failed after only a couple months of regular driving. Leaving me stranded on the side of the road with an engine flooded with gasoline.But this fuel pressure regulator is way better. Better build quality. Better fine tune adjustment. And it has parts that can be replaced if they fail. Unlike the cheaper knock-off products.Bottom line : if you need an adjustable fuel pressure regulator for your Honda/Acura, save yourself the headache of buying cheaper alternatives and learning the hard way. This product is worth every penny. Even though it seems kinda pricey.
