Hi, I’m Mark from eReplacementParts.com. In this video I’m going to show you how to replace the fuel line and filter on a Ryobi trimmer. The fuel filter mounts in the trimmer’s fuel tank. Its purpose is to filter out even the smallest debris before it can enter the carburetor and potentially clog it. The fuel filter will become clogged over time and it will need to be replaced.
Replacing the fuel filter is easy to do, and I’m going to show you how. Fuel filters, as well as many other parts, can be found on our website. Let’s get started.
I’ll begin by removing the rear cover. Now remove the two screws that secure the carburetor to the engine. Now, I can pull the carburetor away and twist it up while removing the throttle cable. Before removing any of the fuel lines from the carburetor or the tank, you’ll want to make sure to drain any gas that might be still in the fuel tank.
Now remove the incoming fuel line from the carburetor and pull it through the carburetor mounting plate. Now remove the incoming fuel line from the fuel tank. The fuel filter nipple passes through the bottom of the tank and this makes for a very tight connection. The easiest way to remove this, since we’re going to be replacing it anyway, is to simply just cut it off.
First, I’ll pry the plastic washer away from the fuel line, and now I’ll just cut that off flush to the tank. Now, I’ll use a small screwdriver to push the remainder of the fuel filter through and into the tank. And I’ll tip the trimmer so that the fuel filter falls out of the gas tank.
Now install our new fuel filter and fuel line assembly. There’s a couple of things I’m going to do to prepare the line to go into the tank a little easier. First, I’m going to cut a taper a little on the end of the line, and I want to cut off as little of the line as possible here. Next, I’ll take some two-cycle mix oil and lubricate the lines so that it will slide through the holes in the tank a little easier. And now, we can install the assembly into the fuel tank.
I’ll insert the fuel line into the tank and try to snag the tapered end we cut on the line on the hole that the fuel line passes through, and I can pull it through and work the nipple on the fuel filter into the opening. Now, using a very large flat tip screwdriver, I’ll insert the screwdriver into the fuel tank and place the tip of the screwdriver on the plastic button that’s on top of the filter. I’ll apply gentle downward force to push the fuel filter into the tank, at the same time pulling on the fuel line on the outside of the tank.
The fuel filter and line kit includes a small plastic washer. This washer goes over the fuel line and under the nipple on the fuel side of the fuel filter, and this locks the fuel filter in place. I just want to slide it up until it’s flush with the underside of the tank. Now insert the fuel line through the hole in the backside of the carburetor plate. I’ll go ahead and cut that end square that we tapered earlier. And again, I want to cut off as little of the line as possible. And I can reinstall it to the carburetor.
Now reinstall the throttle cable back onto the carburetor’s throttle linkage. And I’ll secure the carburetor, as well as the choke plate, with the screws. As I tighten the upper screw, I want to make sure I have the choke plate lined up, as well as the wavy washer, so it doesn’t get pinched by the screw. And now, I’ll install the rear cover with the air filter.
And now you know how to replace the fuel filter and fuel line on your Ryobi trimmer. If you found this video helpful, be sure to give us a thumbs-up, and leave a comment.

This video is as relevent today as it was 7yrs ago. Amazing. I have a Ryoki tiller with the exact same engine. My neighbor gave it to me as a gift for helping him move. I had to replace ALL the fuel lines which were all broken. I cleaned the entire fuel system, including the carb, tank and primer bulb, but I didn't keep track of where the fuel lines connected between the carb, primer and tank. There are three separate lines. Thanks to your video, I know exactly where each new line will go. Can't wait to use it next season. Thanks for posting.
Great video! Your tip on adding some 2 cycle oil to help ease the fuel line into place is invaluable!
Be careful about buying kits with fuel line and filter. The universal RYOBI kit I purchased at Home Depot had wrong size pipes, wrong size filter (too long) with different securing method and only a primer bulb with no primer body. I had to discard everything and order again. By the way, I'm not sure why the easier approach would be to insert the pipe into the tank and put the filter on when the pipe appears. There's no fishing around with the pipe that way. I think the videos are great however, very helpful. Thanks.
Good, straight forward video. I would add that the plastic union that was on the fuel line from the Tank to the Carb's top inlet is added as a reducer from the larger to the smaller I.D. tubing. If it is omitted, the fuel line will vibrate off the carburetor's fitting over time. Remember, all screws need a hole and all holes need a screw.
?? Not too sure why they removed the carb but OK.... That was (by far) the easiest video of the fuel line going through the bottom of the tank that I've ever seen - Great videos!
You sound like a know it all but I guess you deliberately miss the part where the fuel filter was replaced?
Always use the original equipment fuel lines for this!! Anything other than those will give problems as far as leaks, or ease of installation! Great video!
And always remember the long nipple on the primer attaches to the return line..
NO....Oem fuel lines were NOT ethanol resistant! ANY ethanol resistant fuel line of the proper diameter will do. Usually the one's at the mower shop selling for .10 cents a foot are better than oem.
This video is excellent and exactly what I needed in order to accomplish the fuel line replacement myself.
THANK YOU!!!! Especially nice because I have the trimmer used in this demonstration.
Good visuals, explanation and tips...what did people do before RUclips and generous experts?
Than you for taking the time and effort to create this excellent how to video. Very well done. Thanks again!
Glad it was helpful!
very good demonstration and information...simple to follow
Great job , very good& easy instructions. Thanks!
Perfect! Especially the advice on getting the filter line out of he fuel tank
Nice and straight forward instructions
It is quite difficult to install the new filter. The video makes it look easy.
I found that putting the pipe in from the bottom first and then attaching the filter was easier. Also make sure that you have the right filter. Some are too long. Match it up with the old filter.
Very good video. I know exactly what to look for and how to do it. Great job!
Brilliant! Clear concise instructions. Thanks very much.
Great tips on installing this! Thanks!
good detail for the filter replacement
It has two lines how does the green one attach to the petrol tank thanks great video easier than the other one i watched.
A BIG THAMKS I did not know how I would do that thank the Lord and you
Thanks Great info for quick fuelline switchover
great Video for fuel filter replacement
Like ur video loud n clear
Good video Mark.
Thanks for this Mark. Very good production with clear audio and video. I used it to do a first-time repair on my Yardman line trimmer. Just one question. Before replacement, the fuel supply line from the tank is in two pieces, joined by a fuel line coupler. (My Yardman has the same coupler.) However, the repair didn't reinstall a coupler and nor does any other repair video that I've seen. What role does the coupler serve?
wonderful how to replace fuel filter, thanks, i learned how to replace a filter..Al
I use 11inch 45° angled needle pliers.
Is the hose already on the filter nipple? I have aftermarket kit and it's a hard job getting hose on filter and no way is is it coming through the tank
would of loved to see how long it took to get hose into the hole.
Thanks mate. that was exactly what I was looking for.
How do you get the fuel filter end through the hole. Mine stops every time. My fingers don't reach the fuel filter and I have big hands. No problem with the fuel lines but the filter won't go through the hole. I've watched 4-5 videos so I must be clueless.
The so-called universal replacement filters don't fit - nothing but a lot of pulling and frustration. I ordered the part in this video from eReplacementParts and it was a very quick job. A bit of oil or grease helps to get the barbed fitting into the fuel hose and also at the hose where it goes through the bottom of the tank. Only Ryobi Part # 791-682039 will fit.
great video, thanks
Tried replacing the fuel filter line found the piece under the filter is much bigger than the hole stopped pulling from the bottom for fear of breaking something brought my Ryobi trimmer 1998 looked after it needed fuel lines and bulb changed all good up until the filter part ???
Very helpful must appreciated keep up the good work
thanks
Helps alot.
Nice video, although I found the procedure easier by just removing the tank
How do you the remove the back cover off a 25 year old Ryobi 780r 31cc 18" grass trimmer. The choke lever interferes, and its a different choke lever than on your video. I don't want to force it. Any suggestions ?
Very helpful!
I have pulled and pulled and pulled and can't get the nipple through the bottom of the tank. I'm using a Fuel System Tune-up kit, part no, ACO4122.

How to measure the piston ring, inner dia. Or outer dia.?
I want to replacement my piston ring
What about the check valve in the original fuel supply line?
It is PHYSICALLY IMPOSSIBLE to push on the fuel filter with a screwdriver on the Ryobi 790R! The filter is too far from the tank opening! Also it is even MORE impossible to pull the line with the fuel filter nipple through the hole! I pulled with 1000 Ft/lb of force and it WILL NOT PULL THROUGH!! Only stretches the fuel line into a thread! NO worries, I will just go buy a new trimmer as I should have to begin with. Thanks for all the frustration and cussing !!
On my Ryobi 3100 blower, I replaced the pipes but the 3mm ID is too wide, and leaks fuel around the intake nipples on the carburetor. I measured the old pipe and it is actually 2mm ID and about 3.5mm OD. Do you have a filter kit that comes with a 2mm ID hose? Or what else would you suggest? Thanks
I have a Ryan model 284. It appears to be the same carb. Can you verify? I need to replace fuel line and air filter.
I just fought a battle trying to get the new fuel line through the top of the tank - it's a lot easier if you happen to have a fuel line pulling tool.
Put the fuel line up from the bottom first, then add the filter. I found it easier.
Perfect
Great video! Hint: Throw those sorry Snap On side cutters in the trash and go get you a real set at harbor freight! Ha!
Thanks for the tip!
r these lines to different sizes small big ?
Very helpful. Thanks
Spark plug new dj7y seems to hit the piston the old one same number dose not?
I wonder if the plug is some how mislabeled or otherwise defective. I checked the same plug number for the model and these seem to be ok and the DJ7Y should be the correct plug. You may want to try another plug. If you purchased the plug from us, let us know so we can get another plug sent to you.
My lines won't hold prime. Changed lines and cleaned carburetor.
Do you. Have a video for a TROY BILT. tB70ss
Hey guys, at 1:47 he says "nipple" He-he-he-he-he.
Very helpful.
what is the green fuel line I need that one replaced
The green line you're asking about is actually Blue when it comes new. It's the Return fuel line part number 791-181086. www.ereplacementparts.com/fuel-return-line-p-282392.html
791-181086 Fuel Return Line
- eReplacementParts
www.ereplacementparts.com
The purpose of the 791-181086 Fuel Return Tube is to return the excess
fuel back into the fuel tank, after the primer bulb has been pressed and has
primed the ...
Install this by cutting the end of the hose on an angle, getting the old hose out of the tank, put a little oil on the hose the push the angle cut end into the fuel tank.
Would LOVE a video on how to replace that one! (Assuming you mean the fuel line that goes to the primer bulb to the tank.) That one I can't seem to do....
It's smart to use Premium gasoline in small engines. Unlike an automobile it will probably cost only a few dollars a year more. If you bought the Ryobi BP42, return it and get a new one next season. They die after a year or so. Ryobi hillbillies will guide you through all the things that could be wrong. That process requires buying part they suggest, waiting for part, installing new part, calling Ryobi when that didn't fix the problem. I went through this 4 step/week long process-At least 5 times: Air filter(1 week), fuel filter(1 week), carb cleaned, carb replaced with a new one, new fuel and air lines installed, new plug. Over 12 hours and ~$100 into this and I give up. Ryobi sucks. Their hillbilly helpers are in the business of getting you to buy all these solutions!! They don't get paid to actually help you with your problem. If the Chinese blew leaves, they'd make a better leafblower. They don't-Ryobi BP42 is a planned obsolescence product. This piece of crap is actually a terrific leaf blower when it works. Show me a homeowner who was able to fix their BP42 and I'll blow your leaves for a season.
Also...when you're on the phone with them and they ask you for the serial number on your blower, you'll see that the serial number is sleazily hid by an impossible to read microscopic font size. DO NOT PULL THE STICKER OFF TO READ THE NUMBER!! While on the phone with them I pulled it off It voided my warranty. VERY SLEAZY COMPANY!!
😊
your going backwards feed it threw the tank first i don't know how you fished that from the inside lol
Identical to a Troy-Bilt.
No instruction for routing the lines to and from the primer bulb?? This video needs to be deleted and redone properly.
The audio is terrible.
