Works as it should
Install was easy as it fit right into my 5/16 fuel line perfectly on my boat. With the trouble we have on marine fuel systems with ethanol, I like having a spare at this price point. Let’s fuel travel only one way so works as it should.

Works well on Camaro LT1 opti spark vent system.
Used these 1/4 one ways for my 95 Camaro lt1 opti spark system. My old check valves were sticking open and this was a great upgrade. The back flow is solid and the one way is nice because it has a slight open pressure instead of a free float valve. Easy to install, great price and I like the solid metal design of the housing.

These are claimed is hazmat
So here we go if you buy these don’t expect to return them even if they’re bad I didn’t check the second one. I paid $10 for two not for possibly one. The one I attempted to use did not stop atmospheric pressure from allowing the diesel fuel to spill out the only purpose for this was to give me a vent to my transfer tank and it failed seriously at that. I attempted to do a return and it said it was a hazardous material item. Not sure why attempted to contact the seller in two days later still have not heard anything. All I can say is good luck and don’t buy from this company.

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.

works extremely good.
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.
