Review on 🔧 Enhance Fuel Efficiency with Mr. Gasket - 9710 Chrome Fuel Pressure Regulator by Antoine Dean

This regulator worked for about 7 hours in total. He then began reducing the fuel pressure to less than half a pound on a regular basis. It seems to happen after a warm boot. It's not a vapor barrier. I installed a second pressure gauge before the regulator to confirm. The fuel pump has a constant pressure of 9psi, but the pressure gauge behind the regulator reads next to nothing when this happens. I may have gotten a bad one, but I won't get another.
