How to replacing jonsered 70e chainsaw fuel lines

There are 2 lines that go into the fuel tank. One line goes from the carb to the fuel filter inside the fuel tank. It's the other one that I want to learn how to replace. It goes from the top of the fuel tank to the right front side of the air filter compartment and I'm not sure where it goes from there.or what it does. Thanks for any help. wk

Who connected these hoses? the normal routing for a machine with a primer is like this, the fuel hose from the tank with the filter on the end goes to the carb fuel inlet nozzel ( not to the primer ) nearest to the pump cover ( cover on carb held with one screw ) the pipe from the metering side of the carb connects to the shorter nozzel on the primer bulb ( suction side ), the longer nozzel on the primer ( pressure side ) connects to the pipe going back to the tank, just remember the primer pulls fuel from the carb,into the bulb, and pushes it back into the tank, it is not actually a primer it is a purge. because it is connected this way it is impossible to flood the engine no matter how many times the bulb is pressed.
Let me know if it starts and runs.

This sounds like the hose from the tank breather, the hose goes from the tank on the l/h side to the cylindrical vent, then from the other side of the vent the hose goes around the back of the carb and out through the side of the crankcase with a sintered plug in the edn, there is also a hose from the cylinder base, this is the impulse tube and fits to the top of the pump cover of the carb,

Where do gas lines go


Depending on the carb you have, the short side of the primer bulb goes to the carb and the long side of the primer goes to the fuel tank as the return line. The fuel line on the right side of the carb goes to the fuel tank and is the one with the fuel filter.

Easy way to install fuel line and primer bulb return line into gas tank


Chainsaw fuel lines enter the gas tank from holes in top of tank. They are sized for a tight fit to prevent leakage. Make it easy on yourself when pushing the line through the tank by cutting a long lengthwise taper cut with razor knife 3 inches or longer to easily feed through that tight hole. Once started you will then have to grab it through the gas cap hole with needle nose pliers, then cut the tapered end flush and add fuel filter. Readjust inside length by pulling from above, then cut to length to upper carb fitting. If connecting to primer bulb a filter is not required and make sure the line goes to fitting on primer bulb marked tank.

Fuel line diagram poulan wild thing 40cc


I can't give you an actual diagram but a I can try to explain how it should go. There is a line with the filter in the tank that goes to the bottom of the carb, there is another line from the carb that goes to the in port of the primer bulb, the out side of the primer bulb will go back down into the fuel tank. The primer will pull gas from the tank through the carb into the bulb then return the gas from the bulb to the tank

Poulan chain saw model #2025 - fuel lines dry rotted and disintegrated. There are 3 fuel lines: l from gas tank and 2 from primer button but only 2 fuel ports on the carb. What goes where and how?


You should have 2 to the tank, the one with filter coming from tank goes to nipple on right side of carb, the nipple on left side by primer bulb goes to primer bulb and other from primer bulb back to tank as return line, how it should work is when you push primer bulb it pulls fuel from tank through carb and back to tank on return line so watch in tank orleave one line out that you think is return line and see if gas comes out when you prime, but remember it goes through the carb first before it goes back to tank, had a pic but too big to put on site sorry, 2StrokeJim

Trying to put new fuel lines in all around... bulb has two connections, tank and carb. carb has two connections, I imagine that the tank/filter line goes into the carb, carb then goes out to bulb, bulb...


Fuel routing:
Tank to carb (filter on free end in tank, replace annually)
Carb to primer (primer sucks fuel through carb)
Primer to tank (primer returns excess fuel to tank) HTH

Poulan 2050 chainsaw. Fuel line routing. Replaced all fuel lines. Primer bulb is marked Tank and Carb side. Tank side is for larger line and runs into tank and fuel filter. Carb side is smaller diameter...


Replaced my fuel lines on poulan 2050 today. The large diameter line is a return line from the primer to the tank. The smaller diameter line is the supply line from the tank to the carb. You need to cut this line and run a second piece of small diameter line from the card to the primer. I'm not sure if it makes a difference which of the two stems on the carb is the inlet or outlet line. I used the top stem as the inlet, and connected the bottom stem to the primer. My chainsaw started right up. So I either got lucky or maybe it doesn't matter.
