Review on Enhanced Performance: Universal Adjustable EFI Aluminum Fuel Pressure Regulator Kit with Gauge & Fuel Line Fittings (Black) by John Greene

That's what I expected for the money. I immediately disassembled the regulator to inspect the inside. The first thing I noticed was some play in the input thread. Nothing special. Even with the adjustment screw all the way out, the body compresses the heavy spring a quarter of an inch. I assume that if the minimum pressure is too high then the spring may need grinding to reduce the seat pressure. They are filled with liquid. The hoses must be cut off as the ends are flared. I assume that the device works fine with some settings. Fits me for the price. If you're not comfortable making some adjustments, you may want to spend more money on a reputable brand controller. Branded devices cost $100-150 more than this device. I agree to changing this to work to save money. I will add a review after installation.
