Quality Check Valves
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.

Work Great!
Love these things! They do exactly what they’re supposed to do and are made of high quality aluminum.

Game-Changer for Cold Starts – Must-Have for Older Rigs!
I installed the Evil Energy 3/8" inline fuel check valve along with their 300 PSI 3/8" fuel hose on my 1998 Jeep Grand Cherokee (5.2L) — and let me tell you, the difference was night and day. My Jeep already had a new fuel pump and strong pressure readings, but the pressure would drop quickly after shutdown, making cold starts a chore. After adding the check valve into the line, the fuel pressure now holds steady, and startups are instant — no more pumping the throttle or long cranks. It genuinely saved my carbureted-style motor’s life. The valve came as a pair, easy to install, and the directional arrow makes orientation simple. The hose is tough, cleanly built, and rated at 300 PSI, so you know it’s not cheap junk. Whether you're fighting bleed-off issues or just want to protect your fuel system, this is a cheap, high-quality fix. Can’t recommend it enough!

Beware Alcohol based fuel
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.

*** ACTUALIZADO*** En su momento compré dos y ambos no retienen líquido, después de 4 días se ha vacea el contenedor **** Excelente estado, cuidado perfecto y la pieza en excelentes condiciones en embalaje. Incluso llegó antes de lo agendado y lo mejor es que incluye una calcomanía, directa la colección de viaje.
