EVILENERGY Check Valves Editorial Review

This fuel check valve works effectively in an air/vapor system and can fit any 1/4 or 6mm fuel line, but cannot work in a propane gas pipeline. Its installation depends on the application, but it usually installs close to the tank before the fuel pump. It is a quality product that solves fuel delivery issues. However, it has barbed diameters that sometimes require tight worm gear clamps to seal, and some find it difficult to ensure that the fuel hose clamps are tight enough to prevent leaks using appropriate hardware. There are mixed reports about its durability, with some stating that it relieves pressure within two days and requires a re-prime of the manual fuel pump while others state that it works great. Reviewers seem divided about whether or not it is a great value.
