Ryobi 700r gas trimmer, replace old fuel lines

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.

There should be two coming off the carb one is the feed and the other is the return the return just sticks in the tank about a 1/4 inch the feed goes in the tank which has the filter attached to it hook these two up and pump the primer bulb if it continues to pump fuel than its right but if doesn't than just switch them then hook up the third one that's left hope this helps
