Worth the money. - 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. Review: Caution: Fire Hazard - 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. ## Features - Applications: 94-01 Acura Integra RS, LS, GS and GSR - Applications: 86-89 Honda Accord Lxi, Sei and 90-93 Honda Accord DX, LX, SE, EX (Must use AEM Rail) and 92-95 Honda Civic VX, CX, DX, LX and EX - Applications: 99-00 Honda Civic Si and 93-95 Honda Del Sol S, Si and 94-97 Honda Del Sol VTEC - Applications: 88-91 Honda Prelude Si and 92-96 Honda Prelude S (Must use AEM Rail) - Adjustable from 20 psi to maximum fuel pump capacity ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002YXCT3W | | Auto Part Position | Inside | | Automotive Fit Type | Vehicle Specific Fit | | Body Material | Aluminum | | Brand | AEM | | Brand Name | AEM | | Compatible with Vehicle Type | Car | | Connector Type | ON | | Customer Reviews | 4.3 out of 5 stars 209 Reviews | | Fit Type | Vehicle Specific Fit | | Fit type | Vehicle Specific Fit | | Gas Type | Gasoline | | Global Trade Identification Number | 00840879019860 | | Inlet Connection Size | 0.38 Inches | | Inlet Connection Type | Threaded | | Item Weight | 0.25 Kilograms | | Item weight | 0.25 Kilograms | | Manufacturer | AEM | | Manufacturer Part Number | 25-300BK | | Material | Aluminum | | Material Type | Aluminum | | Model Number | 25-300BK | | Mounting Type | Rail Mount | | OEM Equivalent Part Number | 25-300BK | | Operation Mode | Mechanical | | Outlet Connection Size | 0.25 Inches | | Outlet Connection Type | AN | | Part Interchange Info | 25-300BK | | Product Grade | New | | Product Style | Custom | | Specification Met | OE | | Style | Custom | | UPC | 840879019860 | | Unit Count | 1 Count | | Vehicle service type | Car | ## Product Details - **Brand:** AEM - **Fit type:** Vehicle Specific Fit - **Item weight:** 0.25 Kilograms - **Material:** Aluminum - **Vehicle service type:** Car ## Images ![25-300BK Black High Volume Adjustable Fuel Pressure Regulator - Image 1](https://m.media-amazon.com/images/I/618dqIq7vTL.jpg) ## Questions & Answers **Q: What is the possible psi out?** A: We have them set at 55 psi **Q: Will it work with a.
