Review on 🔋 Enhance Fuel Efficiency & Safety: Tkkeuep Racing Fuels Filler Hose with Ball Valve Shut-Off Hose Kit for VP Racing Fuel Containers, Jegs Jugs, LC2 Jugs, Scribner Fuel Jugs by Stephen Parkell

Looks good, but it's not. The first time you use it, the second time you try to use it, the plastic flaps lock so tightly you can even twist them. Maybe it's the ethanol in the fuel that causes the plastic to swell. But valves are junk after you can't open and close them. I ended up removing the plastic valves and just using the filler caps. You really need brass ball valves. The plastic bottles they come with are not designed for fuel.
