EVIL ENERGY 1/4" Fuel Check Valve One Way Inline Non Return Diesel Gasoline Silver (6mm OD,2PCS)

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

Nice quality stuff. Got for use in making custom oil catch can kits for a couple trucks.

I put one by the tank on my '72 CJ5. It held fuel for 24 hours but seemed to leak back after 48 hours. I just added the second one in the in the engine bay. I have an electric pump so running it with no fuel in the line would likely shorten its life span. The second will hopefully keep enough fuel by the pump to eliminate that risk. After adding the second valve in the engine bay my Jeep started with no problem after sitting for a few days and kept running without starving for fuel. It's got a 360 innit and just kept rumbling. Evil Energy offered my money back but since one wouldn't keep the line full, but for the price, having two valves in place I have no complaints whatsoever with this product. I highly recommend!

This inline Fuel line Check Valve was fairly EZ to install. Seams to work well on my 455 Oldsmobile engine. Haven't had it on very long so don't know how well it will work on the long run. I would say try it for what they cost. I just got 2 more of these Fuel Line Check Values, I plan on butting one on another Olds engine, This time I am going to put it in the gas line between the fuel pump and the Carb. I feel that the one I put on the 455 Olds engine that I put inline before the fuel pump, doing this I feel the fuel drains back from the carb to the return line in the fuel pump when the car sits. I think by putting it between the fuel pump and carb that will stop the drain back.

They work well for letting fluid through. They dont flow at first, but if you put some fluid through and add a little pressure they will flow. Once they have fluid in them they continue to flow. I think they just need the initial lubricity then all good.

Great company to deal with excellent product

Work great, got what I ordered.

Works well for a bit, then fails. Apparently, our crappy alcohol mixture kills it. This one last one month.

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.

Recommend

put on my RV for the generator so gas isn't sucked back to main fuel tank making much easier to start without constantly priming.

sure was made from good material , but the flow not what you can expected.
