Question about Ryobi 30 Cubic Centimeter Curved Shaft Gas Trimmer

1 Answer

Can someone tell me where to find replacement fuel hose for this style of Ryobi? The existing line has hardened with time and is leaking fuel / sucking air iat an inline connection below the primer bulb. I have looked online for about an hour and have not found any.

Your local repair shop should carry this fuel line in large quantities and sell it by the foot or by the inch. Your Ryobi probably uses Homelite's 3/64" line.
Homelite #70310-98 or Rotary #20-8645
Homelite Consumer Products is the company that made your 30cc Ryobi trimmer. At their website ( they offer a replacement tank assembly which would include the fuel line.
I think your best opportunity is with the local repair shop.
Good luck!

Need to replace the gas lines to and from the carb. Also within the tank.

if it has a primer bulb , the line probably goes to that
It may you to consider a new fuel tank as they come with all hoses , new cap , line filter in the tank
The hose is not plastic but a silicon hose which although short is very expensive plus the fact that you have to get it through the stopper in the tank ( which is probably leaking as well)
I have just replaced the tank assembly for a ryobi 25cc trimmer for $40.00 aud and I feel sure that you will spend almost that in replacing the lines , in time

Gas leaking from my tank switch

Use compression barb fittings on the pressure side with fuel injection line NOT REGULAR FUEL HOSE THE REGULAR HOSE WONT HOLD UP TO THE PRESSURE. The return line can be regular fuel line because of the low pressure.

Can I repair a fuel line leak with tape or any sort of sealant so that I can drive it to a shop? 1993 Oldsmobile Ciera

not sealant But get small length of rubber hose,,, small ,as in just larger than metal line then get two small screw band clamps cut the leak spot with bolt cutters QUICKLY insert hose on two ends of line with CLAMPS ALREADY ON HOSE screw them tight stop at service dest inform them of gas leak so they can take precautions.

they will ask fix or replace say FIX so they don't chage you $120 an hour shop time to bend fuel line hose to replace entire line... NOT necessary..old school repair if fine replace line is $$$ and not neccessary very little pressure in fuel line mostly gravity flow you may even say its more practical

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.

Ryobi 725r leaks gas from air filter and will cut out after starting up

This is a problem with most ryobi tools. From what i've read over time the gas lines shrink and need to be replaced. You'll need to replace both the lines coming from the carb to engine and the one connecting to your primer bulb. I hear there is a kit that contains both the primer bulb and fuel lines for this exact problem.

How far does the return gas line on a ryobi string trimmer extend

There is supposed to be a barb fitting with a flange on top of it that is on the end of the hose, inside the tank. If you do not have that barb in place the gas will start to leak out of the tank in a short time. Barb fitting is designed to have hose stick up about 3/16" into the tank when the hose is properly installed. You put the new hose on the fitting, thread the other end of the hose through the fill opening of the tank and out the hole in the bottom. Pull hose through until barb comes through the hole in the tank and the flange is flush with the inside bottom of the tank. There is supposed to be a plastic ring that fits over the bulge in the hose/barb at the bottom of the tank on the outside. Serves as a retainer for the fitting.

I had exactly the same problem after I changed the fuel filter. Tried new clamps and tightening them etc. Nothing worked until I purchased a foot long hose from a auto store for couple bucks and replaced the both ends with the new hoses. Old hose hardens over time and it doesn't seal well after it has been reused.
