AEM Fuel Pressure Regulator 25303 - FPR Honda Style

AEM Adjustable FPR Fuel Pressure Regulator 25-303

We offer the AEM Fuel Pressure Regulators model 25-303. These are known for being great adjustable FPR's. The catch is they are specific for varous Honda/Acura engines. BUT, we also offer it with our Honda-Style FPR Fuel Rail Adapter which allows you to connect the FPR directly to the 3000GT/Stealth fuel rail, replacing the stock FPR with an aftermarket adjustable one, and without having to get special lines or anything. The big advantage of these FPRs is their sheer size - this FPR is about half the size of the other regulators we offer, and the fact that it will mount directly to the stock fuel rail using our adapter (offered separately) is a big bonus.

Fuel Rail Adapter for 3000GT/Stealth fits Honda-Style AEM FPR 25303

This adapter allows you to adapt your fuel system to use a Honda-type fuel pressure regulator. You remove your factory FPR and install this adapter on the end of your fuel rail, then mount the Honda-style FPR to this adapter. The advantage of this is that you can now install an adjustable FPR without having to modify lines - it mounts to your fuel rail and the return line mounts to the FPR since they typically have a barbed fitting-nipple for the fuel return line.

 

NOTE: AEM has discontinued the colors, making black the only option available.
