This 38 mm fuel hose is a genuine OEM sourced item, it is not an aftermarket imitation. It is high quality item specially designed for Husqvarna chainsaws, brushcutters and string trimmers. This hose is connected to the carburetor. Over time fuel lines tend to deteriorate and crack allowing for leaks. A damaged or brittle line should be replaced immediately. Please note, one flexible plastic fuel hose is included per order.
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, prob
... Read moreably 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.

Fuel tank bushing was leaking and fuel line had wore out
1. I examined the fuel leak and determined that the fuel line and bushing was leaking.
2. I removed the fuel filter, and then removed the fuel line with a pair of needle nose pliers.
3. Then with the needle nose pliers I placed the bushing in the hole on the top of the fuel tank, and then placed the fuel line in the bushing as
... Read more far as what was needed to attach the fuel line to the carburetor, the other end I pulled out of the fuel tank fuel hole and attached the new fuel filter.

Wear and tear, leaking bar oil, fuel lined cracked and running lean,
Took off top cover, disconnected hoses, disconnected air purge assembly and attached new assembly, attached hoses, replaced cover, poured in fuel/oil mixture, primed the air purge, and started the chainsaw right up for the first time in 3 years with only 3 pulls. Works great with zero problems.
