Fuel Hose 591375201

1. Remove chain and bar( for easy maneuverability), empty gas in tank, then top cover, followed by handle and throttle grip. The throttle has to be disconnected from carb, and you have to spin the linkage to remove because it does not come straight out.
2. You can choose to remove carb, I was able to do repair without removing, probably more difficult, but might have saved a little time. I removed return line and fuel lines and prime bulb from saw, followed by grommets. To remove fuel line you have to open gas tank and pull out filter and fuel line with your 90 degree pick. Remove filter and hose, replace with new.
3. When I replaced grommets and hose, I put a little oil on them to make things go on a little easier. I found it is easier to install grommets on hose first and then install grommets on saw. You can always push and pull hose through.
4. Once all hoses are on and secure, reinstall your filter on line and replace inside tank. I cut about two inches off the tank line before installing filter, just because it seemed a little long, your choice. I only had one line that was bad, but I figured while I was replacing one, might as well do them all, the others are probably going to fail soon.
5. In order to replace exhaust screen, you will have to remove chain break handle, two hex head bolts, slide screen out, slide new one in and done.
6. Once installed, I reassembled everything in the reverse order it come out. Chain brake handle, main handle then throttle cover, remember to install throttle linkage, you have to spin it to get back next to the carb, this can be a little tedious, but make sure it is where it needs to go before bolting main handle on, or you have to take it apart again(my mistake).
7. After throttle cover, replace your top cover, and chain and bar, add gas and your good to go.

Drained fuel. Took old fuel hose out.removed fuel filter, replaced filter on new hose. Removed other end from carburetor. Put on new fuel hose in..(a little tough) but chainsaw works flawlessly now. I have a Husqvarna 345.

Removed saw from handles and frame, disassembled the carburetor and throttle linkage. Replaced fuel filter and gromment along with the bad fuel line and reassembled.

Replaced the primer bulb (air purge), and the fuel line from the carburetor to the tank. Have to remove the cylinder cover and air filter to access fuel lines. Getting the new fuel line into the tank beside the carburetor is the most difficult part. The fuel line is spiraled, or coiled from the factory and is this way on purpose so it can flop back and forth inside the tank regardless of what position the chainsaw is held. This creates a bit of an issue getting the fuel line into the small bushing it goes thru in the tank. A little ingenuity and patience will get it done. I used the hemostats and a very long piece of wire to pull the fuel line thru into the tank. The hemostats also helped out greatly getting the new fuel line in place on the nipple on the carburetor because the throttle linkage does not leave enough room for fingers.

Took top of saw apart to get to the opening where the fuel line goes from the carb to the tank. installed new hose and original fuel filter. Installed straight hose. Put the saw back together. Runs fine after repair.

Watched u-tube videos for each individual repair

look at youtube

Removed top cover & replaced the hose from primer bulb to fuel tank. Hose had to be pushed in to grommet above tank. This required the use of locking forceps to force the hose in to the grommet.

replace the above parts along with the primer bulb

It went well , the old Gas line originally made from transparent flexible plastic was 50 thousand of an inched smaller than the replacement line purchased , the new one was made of rubber meaning that it had a better seal as it went trough the gas tanks , this one being 50 thousand larger than the original provided a better seal so I did not lost pressure in the tank meaning the saw no longer starved for gas .
I am very satisfy with the result.
