Review on 🔒 High-Performance Fuel Non Return Check Valve - 10mm/3/8 inch, Aluminum Alloy - Ideal for Petrol and Diesel Applications by Charley Martinez

As some others have said, this check valve failed soon, and in my case immediately. The low-pressure fuel pump raised the pressure in the engine's fuel rail to just 35 psi, and when the pump shut off, the back flow of fuel immediately ruptured the inside of the check valve, causing the gauge to drop to zero immediately instead of staying at 35 psi inches. After removing the check valve you could see the clean inside of the check valve as the insides are gone probably now in the engine fuel rail waiting for the injector to get clogged. Immediately after. The similar looking Muzzy brand (among other similar options) which I bought as an extra also failed in the same way. After a long, hard search for the best quality barbed, I ordered a $46 Stratoflex 3395RB-H38 stainless steel check valve, spring loaded internals with Viton seals, rated to 300 psi. At least made in the USA with the right materials and should hopefully work well.
