Primer and Hose Assembly

The fuel line and filter, primer and hose assembly, and the fuel return line had deteriorated over time and were leaking fuel. I found the parts here and ordered them. When the parts arrived, I removed four screws from the rear cover on the engine, pulled off the old hoses and put the new ones on. I screwed the rear cover in place and was done in about 30 minutes or less.

The priming bulb has disintegrated in this trimmer. Unit came with one gas line, simple swap. Website had great tools to ID the part, match it to model of trimmer. Just mind what hose goes where. Note the replacement hose will need an angle cut to go into the gas tank easier.

1,removed the muffler and air filter housing four mount screws with the screwdriver
2,removed the center fuel tube leads from carburetor to the primer bulb outer connecting tube (make sure the fuel tank is empty of any fuel)
3,remove only the tube leading from the outer primer bulb connection to the inner hole in the fuel tank.
4,unsnap the old primer bulb from the mount by squeezing the lock arms and pull the bulb assembly rearward.
Install the new tube to the longer outer connection port. Then cut a 45 degree angle on the loose end of the tube.
2,install the new primer bulb and tube into the mount bracket *you may have to squeeze the mount locks inward slightly bending them towards each other to get them in through the mount bracket hole. They fit tight.
3,put a drop of oil on the 45 degree end of the tube. Using needle nose pliers force the 45°end through the inner hole of the fuel tank. Look through the fuel cap opening of the tank to be sure all the 45°end is inside the tank.
Reinstall the muffler and air filter housing. Fuel up and go.

Removed old primer bulb and hose and replace with new primer bulb and hose, started up just fine. Ryobi gas engine , with extensions.

No instructions were included with the replacement part so I watched ereplacementparts video on youtube. This made repair really easy.

Removed carburetor and cleaned all internal parts. replaced all full lines, primer bulb and gas filter. Replaced spark plug. Started on 2nd pull and runs like a champ.

Since it was half apart the replacement was simple:
1. I used the pliers to pull the fuel lines off the bulb.
2. Squeezed the tabs in to release the bulb.
3. Inserted new bulb until it snapped in.
4. Slid fuel lines on.

Remove cover, loosen carburetor, pull up to get gas tank out, put new hoses in, ran from gas tank to carburetor. Needed 3 new hoses and primer, reconnected them, snapped new primer in place and put back together.

1. Removed cover over carburetor, four screws.
2. Removed carburetor, two screws.
3.Inserted hoses and primer. Used sockets and a nut driver to get filter and fuel line into tank. This was the innovative part if the installation.
4 .Reassembled carburetor and cover.
5. Gassed it up and it ran..

Replaced each fuel line one at a time. Very easy except for the fuel tank line that had the filter already installed. Needed to go from inside the tank and then push it in place from the inside. An "L" shaped tool helped. Otherwise very easy and did not need to purchase a new trimmer.
