The EVIL ENERGY 3/8" Fuel Check Valve is a durable, precision-engineered inline non-return valve made from corrosion-resistant 6061-T6 aluminum alloy. Designed to maintain stable fuel pressure with a stainless steel spring mechanism, it supports a wide operating pressure range (0.2–6 bar) and temperature extremes (-22℉ to 266℉). Easy to install with barb fittings, it’s the go-to upgrade for carbureted and low-pressure fuel systems, ensuring reliable cold starts and preventing fuel backflow in diesel, gasoline, and other compatible fluids.

Great for Jeep Tj
Works great on my jeep tj. New fuel pump a few months back and the check valve went bad pretty fast. I chased a lot of issues( maintenance items that needed serviced anyways) but no more cold start issues. Fires right up. Will update in a month or so if it dies on me. But they’re cheap, and only take a few minutes to swap out

Have not used yet.
Bought for a dual oil catch can setup. I never did use these.. looks well made.

Not a strong check valve.
These have a very flimsy rubber diaphragm that will dislodge more than it'll stay in place and cause fuel flow problems because it rolls into the outlet nozzle and blocks fuel flow. Happened on 3 different ones in a 55psi fuel injection system gas line. Toss them. Not robust.

Quality and correctly sized
Nice construction, used for pond water feature rather than fuel so s tad over engineered for the purpose but I like that. Good fit well made.
