Review: 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!
Review: Very well made and works perfectly! - A diesel mechanic recommended that I install a check valve in the fuel line near the fuel tank to solve the problem of my boat engine stalling 20-30 seconds after starting. This problem had plagued me for months and a I had fruitlessly spent a lot of money try to 'fix' the problem. It turned out that this very inexpensive check valve solved the issue! Yea! I am VERY happy!! It was super simple to install it in the fuel line near the tank. It is really well made and I now have a spare because I only needed one of them.
