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.
