Review on 🔒 DORMAN 904-203 Black Fuel Filter Cap: Enhance Fuel Efficiency and Protection by Geoffrey Graham

Worked for 6 months and the seal broke. Diesel fuel leak between fuel tank and plastic cap. The "O-ring" (not really an "O" but more of a triangle/wedge shape) looks deformed after 6 months in the truck. Less than 5,000 km driven since installation. First I noticed that the fuel consumption wasn't as good as I'm used to and then I saw the location of the leak on the gravel. I installed a new drain valve/seals as that is usually the culprit but it is still leaking. Fired and right. I can see fuel droplets forming on the edge of the lid. Obviously the gasket is not holding the fuel in the fuel tank. Damn. Now I need to replace the PATH before the filter needs to be replaced.
