The part previously recommended is not the correct part if it is the return line that is bad. Return line does not use the filter. If yours is like all the Ryobi units that I have seen you just need a piece (about 3-4" needed, but buy extra.) of 1/8 ID fuel line. You can usually order that from parts suppliers. Hardware stores will not have it. There is a fitting with a hose barb on it that fits through the tank. On the outside of the tank on the bottom there will be a round plastic ring, assuming the fitting is still in place and just the hose split at the fitting. Use a knife or thin blade of some type to pry off ring. It is actually around the hose that is over the barb. Keep ring, you will need again. Now push fitting up into the tank. You may have to trim off the hose that is outside the tank on the barb to get it to go into the tank. Shake tank around and get fitting out of tank. You will see there is a piece of hose on it yet. Remove that piece of hose. Now take the new hose and slide it onto the barb. It must go all the way to the top of the barb fitting so that the hose actually goes into the tank through the hole drilled in the tank. The OD of the hose acts as the seal to keep gas from leaking out of the tank. You may need to put some oil of some type (vegtable oil works well) on the barb and inside of hose to help slip it on and use some pliers with smooth or rounded jaws ( no serrations, will damage hose) to get hose on. Thread other end of hose into the fill hole of the tank and out the hole in the bottom of the tank. Hint: Straighten out paper clip or use small wire inserted into the hole from the bottom of the tank up towards the fill opening. Slip tube over that and use the wire to guid the tube directly to the opening. Pull hose through the tank. When fitting with barb and hose over it reached the hole in the tank it will resist being pulled through. Carefully pull firmly on hose to strech it so the hose/fitting "bulge" pulls into the hole in the tank. Look into tank and see when top flange of fitting is tight agains the bottom inside of tank. You should see bottom of barb outside of the tank with the hose on it. Once in place put the plastic retainer ring back over hose and push up to bottom of tank. It should fit snuggly when you get to the "bulge" area. Cut hose length as needed to fit onto straight tube fitting on primer bulb. Should be good to go. You may find that the other hoses are getting bad also and may want to change them at the same time, as they will probably be ready to crack also. You can reuse filter from tank if it is not plugged, just add a new hose as described previously. Otherwise you can order a new filter with the line already on it. That is the part that was recommended to you earlier. That line goes directly to the carb inlet barb. That barb is also hard to push hose on. Third line is from the return side of the carb to the suction side of the primer bulb. That is just a straight piece of 1/8" ID hose and pushes onto straight tube fittings, very easy to get hose on compared to barb fittings.

Hope this helps. Contact me if you have any questions.

    Need to make a correction to my previous post. The hose needs to be 3/32" ID, not 1/8" ID. Brain was in neutral. Proper hose for older Ryobi/Ryan/IDC trimmers is 3/32" ID x 3/16 OD.

Look on the carb for 2 screws side by side. where those screws go into the carb, it will be stamped with an "H" and "L". Open the screw that is next to the "H", counterclockwise about 1/4 turn at a time with the engine running, that should solve it.

It is not too hard. Just make sure to cut the new fuel filter line long enough so that you can get ahold of it inside the fuel tank to install the filter. The fuel return line only has to go into the tank 1/2" or more to do it's job, so lenth is not a problem unless you wish to install one of the little nylon connectors on it's end so it doesn't pull OUT of the tank. That is optional.

The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so

Ryobi 700r gas trimmer. Leaking fuel from the fuel return line...what is the best way to fix this?...seems to be leaking where the tube goes up into the fuel tank. thanks.


There is no nipple. The fuel line is just pushed through and holds itself tight against the hole in the tank.

This is the return line from the primer bulb, right?

Just replace the line and you should be fine. I think that some of these Ryobi lines are 3/16 OD and 3/32 ID, but I just picked up a Ryobi fuel line kit at Home Depot today, and the black line seems to fit nicely here. (My trimmer still won't start, but at least it doesn't leak gas any more.) Be careful to note which line comes from where on the orimer bulb.

I have a roybi 31cc weed eater and the fule line has become brittle and has broken apart. I need to know the layout of the new plastic fule line. I purchased a new fule line at Lowe's. I do not know wich...


STEP (1) The fuel supply line has the filter attached inside the fuel tank. The other end of that line goes on the carburetor's SUPPLY NIPPLE.

STEP (2) Determine the primer bulb's flow direction by pumping it under water. The unused nipple on the carb (IF STEP 1 WAS DONE CORRECTLY THERE IS ONE UNUSED NIPPLE STILL AVAILABLE ON THE CARB) will have a section of fuel line attached to it and running to the SUCTION NIPPLE (or pull-side, as some techs call it) of the primer bulb.

STEP(3) The final piece of fuel line goes from the OUTPUT NIPPLE (or push-side, as some techs call it) of the primer bulb and is routed back into the fuel tank as a return.

If plumbed properly, the primer should PULL fuel thru the carb and NOT pump any fuel into the engine. Excess fuel should be pumped back into the tank on each and every press of the primer.

Hope this helps!
