I replaced the fuel line from the gas tank on my Ryobi Cultivator. But it leaks. I don't know why. I installed it according to the directions. A tank of gas will leak out overnight. How can I stop the leak?

after you insert the fuel line through the tank and install the filter. take some WD-40 and spray the hose. now from the bottom of tank the pull on the hose. and just keep pulling on it till it comes through all the way. then slide the little white washer back over the hose and seat in place. this should do it for you. they are a royal pain in the **** to work on. numerous brands of string trimmers have these top mount tanks. a new tank with hoses already assembled is about 45 bucks with shipping. much cheaper to fix it yourself.

The linefrom the tank with the filter goes to the mixture inlet on carb. The fuel return goes to the suction side of bulb. The bulb outlet line goes to the tank. Hopes this helps

Line from tank with the filter on it is the supply line and goes to the carb inlet fitting. This is typically on the "bottom" of the carb (with the tank being up) and will usually have a fitting with barbs or a bulge on it to ensure a tight fit. The other fitting on the carb is the return line and is usually a straight tube fitting with no barbs. That line goes the suction side of the primer bulb. The third line goes from the outlet of the primer bulb to the return barb fitting in the bottom of the tank. Fittings have to be removed from tank to properly install the new hoses on them. Remove retainer ring on outide of tank and push fittings into tank, then shake out of the fill opening. More details on replacing hoses are listed in another post about Repairing Ryobi trimmer.
To leemineres, if hoses are on right and unit still stalls after starting initially you probably need to disassemble carb and clean out using spray carb cleaner. May be sticky needle valve, or partially plugged port or jet.Could also be hole in diaphragm. Gasket and diaphragm kit would be good to add when you take apart, even if diaphragm does not have a hole.
