Lever Fuel Valve Click to Cut the Line

It does not sit on the tank; it sits on the fuel line, and one flip of the lever cuts the fuel. The Click lever fuel valve does exactly that.

It is a different thing from the tank petcock. The petcock sits at the tank outlet and lets gravity feed the fuel down. This lever valve sits on the fuel line itself, and whether the fuel comes by gravity or by pump, one turn of the spool shuts the line. That is why it suits machines with a fuel pump, mowers, go karts, water pumps, generators; run the line where it needs to go, and put the valve wherever you need a shutoff.

Why a lever? A lever arm rides on the center post, and one flip of it turns the spool a quarter turn, from open to closed. A pin in the lever drops into its hole and holds it, so it does not spring back. The clean click of that flip is where the name comes from.

What are the two brass bushings in the flange for? The valve bolts to the machine through its two-hole flange, and the flange carries brass bushings, so the screws bite into the bushing, not into thin metal or plastic. The bushings stand up to wear and re-tightening, and the flange does not strip, so the valve body is not ruined by the screws.

Why does the bracket ship with the valve? The valve needs to sit next to the fuel line, and it cannot hang loose, so it needs a fixed point. The bracket pins the valve in place, and it sets the lever facing a direction the hand can reach. Valve and bracket are matched together, so fitting is quick.

When to replace it? The lever will not flip, fuel still flows when it is closed, the body seeps, the bushing has stripped, or the flange is cracked; then replace the whole unit. The spool and spring are not sold on their own, the valve is one piece.

What to watch when fitting it? Cut the fuel before you take it off, because the line still holds fuel and it will spray. Line up the flange holes, the lever direction and the fuel port on the new valve against the old one. Machines of the same type mostly fit, but fit is not guaranteed for every one, so comparing against the old part is the safe way. Once fitted, flip it twice to make sure it really shuts, then let the fuel back in and check every joint for weeping.
