I have an old Homelite XL101 chain saw that ran great. Gradually it began to lose power. Over time the fuel line in the fuel tank deteriorated. Is replacement fuel line available as well as a new part for the end of the fuel line (it's a weight and possibly a filter that keeps the fuel line in fuel as the saw may be in different positions)?
Can anyone provide part numbers, availability, etc.?
The piese on the end of the fuel line is a pickup filter. if you can blow thru it, then it is still good and you dont have to replace it, but if you want to, you can get them and the fuel line from your local small engine shop. if you have a menards or home depot in your area they ussually carry the line & filters aswell. you will need to take a piese of the old line with you, so you can match the size. the line going into the tank usually seal due to the hole being smaller than the plastic hose, which makes feeding it interresting. i just heat a 1/4 inch or so of the end just enough to stretch it out. this causes the diameter to shrink,then melt the tip& roll it into a point. as you feed it thru, use a couple drops of oil so it pulls easy and does'nt stretch(which will effect the seal). pull enough hose thru so that the filter will lay flat in the bottom right hand corner (as looking from rear of saw toward the tip of the chain) of the tank. this ensures that you pickup fuel when you tip the saw on its side.

There could be a problem with either the fuel line going to the carb or the impulse line that's connected from the cylinder base that generates the 'pulsing' action that operates the diaphragm fuel pump. Today's alcohol rich gasoline has a tendency to weaken or even rot the rubber lines causing fuel delivery issues.
If you don't use your saw for extended periods, dump the tank empty then start the engine and run the residual gasoline from the line. This will help extend the life of the fuel lines.
Another possibility could be a blocked fuel filter, but that is remote.
This is a tedious task but you can do it without taking anything apart the best think I've found is to go to small engine parts store and get the same size (fuel line) don't let them give you air line . Find a good long pair of tweezers and a bench vise you can bend them enough to be able to get into the fuel tank and connect the fuel line and away you go.
Remove the old fuel line and filter from the tank...
You will insert a wire a little smaller than the diameter of the inside of the fuel line, and you will bend a small hook on the end of the line to fit over the fuel line (be sure to use a small wire) .
Lubricate the first 1 inch of fuel line with vasoline lightly...using your fingers or neednose pliers collapse the fuel line and insert it into the fuel tank, entend the fuel line long enought to go out of the fuel tank so you can reconnect the fuel filter...then pull some of the fuel line back into the fuel tank...
Please take time to rate me thumbs up
The line at the back of the tank gets the filter (check it for plugging) and the one nearest the cap doesn't use a filter (it is the return line from the primer bulb). The filtered line goes directly to the carburetor inlet port and the outlet port allows fuel to be pulled through the carburetor and out to the primer port. Check and replace any fuel lines that are in poor condition. If the engine has been running with the intake filter missing, the interior of the carburetor may be full of debris. Remove, dismantle, and clean the carburetor interior. Go to: http://www.drystacked.com for an excellent 12 page article on Walbro carburetor theory and troubleshooting. Hope this helps!
The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best; components are listed but on multiple illustrations. Homelite/Ryobi.com (authorized parts supplier) https://www.gardnerinc.com/recons/disclaimer-lg.php - Agree; Choose “Product Line”; “Select OEM” & “Select Catalog” both to “Homelite Consumer Products”. A drop down list appears; self explanatory from here. The numbers Homelite & Ryobi use do not match the numbers everyone posts. A careful inspection of your saw should find something that matches.

You give this same answer for every fuel line replacement but what is the real trick to getting the fuel line back 'into' the tank, especially in a Poulan where there is no soft rubber grommet that will expand..
