Poulan TE450CXL will not start after replacing fuel line

Just replaced the fuel line which goes from the primer bulb to what appears to be a fuel filter inside the tank. Now my Poulan TE450CXL will not start. At first, the engine started but only ran for about 5 or 10 seconds then died. Now it will not fire. The ignition switch is on. The fuel lines do have fuel in them. The fuel tank is full. Is there are certain way to replace the fuel line?

    So, you're saying the bulb, which attaches to the primer bulb fuel line needs to go all the way to the bottom of the tank? And not at the top portion of the tank?

  • rmienscowjr Sep 05, 2009

    How far does the weighted filter have to sit inside the fuel tank? When I pulled it out of the fuel tank after the original line broke the amount of line left on the filter appeared to only allow it to sit at the top of the tank. So, when I installed the new fuel line I cut enough for the filter to stay at the top portion of the fuel tank.I always set the choke at full for six strokes, then move it to 1/2 position and crank it again until it starts. Once it starts I move the choke to off. The throttle is wide open whenever I crank it to get it started. This is the directions from the manual. The weedeater was running until the original line, which is connected to the weighted fuel filter, broke.

    That appears to be the case because when I push the primer bulb it really doesn't get hard like it used to before when it was operating. Also, when I push the primer bulb (I just checked it) there are lots of air bubbles streaming in the line to the primer bulb. Is that also a symptom for the filter being too high?

  • rmienscowjr Sep 05, 2009

    Well, I'm making some progress. I got the motor to start once but it died in about 10 seconds because I'm still getting lots of air in the primer line. I had extra fuel line so I cut off a piece long enough for the fuel filter to sit at the bottom of the tank but when I prime the bulb I get all sorts of air. In fact, the fuel line to the primer bulb doesn't retain any fuel after I push the bulb several times. Could this be caused by the fuel filter?

  • rmienscowjr Sep 06, 2009

    I let it sit overnight and was able to get it running for about 5 seconds and then it died. I tried it again with similar results until it wouldn't run. There is a good spark. I did notice that when I pulled the spark plug out after I couldn't get it started anymore that it was sort of wet. I removed the plastic cover for the motor which reveals the inside of the bottom portion of the motor block and noticed there was a bit of an accumulation of fuel where the piston crank is.

    What do you mean by the "ring/seal"? I didn't notice any kind of ring or seal? Where would it be located?

The filter goes into the tank. make sure you have moved the ring/seal all the way to the bottom of the filter.

I wouldn't think it would matter how the line goes on. It may be flooded, let it sit overnight if you can. Resist the urge to push the primer button, and put the choke on. Pull started cord until it rumbles, and probably dies. Go to half choke, pull cord, if it starts to run, try to keep it running to warm it up, then turn off choke, or maybe as soon as it starts to run turn off choke, whichever is best for yours. You might take the spark plug out, and see if it is saturated with gas. Make sure the plug is dried off, a cigarette lighter can work, but be careful not to do it close to gas fumes. Put the plug in the wire and ground the end of it on the motor, and gently pull the cord to see if it gets spark. Could be a plugged fuel filter (doubtful), but more likely a dirty air filter also.

No there isn't , if you replaced it then you would prime the fuel so it pulls gas to the carb then it fires. No special science to it. Try making sure the ball on bottom of fuel line in the tank falls to the bottom of the tank where the gas is and if there isn't one there you need to put one thre so when you turn the weedwhip and the gas moves the fuel line always falls where the gas goes. Other then that make sure your lines are tight and nothing else is required if the lines were connected properly to the correct inputs.

    No, the bulb that you squeeze should be near the carb (put it the way you old one was). There should be a weighted filter that sits inside the gas tank that keeps the bottom of the line submerged in gas. If you turn the whip on its side the gas goes to the side and the weight also moves your gas line to the side so it stays where the gas is. If you pump the primer and it sucks gas from the tank to the carb (you can feel when the bulb is full its harder to squeeze) it should fire. Try to make sure the choke is on for the first pull or two and as soon as it tries to fire/fires I take the choke off or turn it 1/2 and it will usually fire or the third time with no problem if the choke is off. Make sure you holding the throttle wide open when starting. Are you running mixed gas (gas/oil) make sure you are to avoid burning the motor up. Also was this running fine before you changed the gas line or did you buy it to repair, if you are not sure it may need to be adjusted (gas/air mix).

    That's your problem. You should not have cut the line. It needs to sit on the bottom of the tank so when your gas is low it will still siphon the little at the bottom of the tank. Now with it being short you can only use it with a full tank of gas and when it gets down a little (probably your 10min) it will stall or will run on those gas vapors until the gas gets low enough to where the vapors arent' strong enough to push through the tube. you need to purchase a longer line and it shold sit on the bottom of the tank (just like the straw in a squirt bottle).

    James Brooks Sep 05, 2009

    Not so much only a symtom of being too high but not enough gas getting in the line from the tank. SO its sucking partial gas/air since its not submerged in the gas. Either the line being too high, gas is low or fittings not tight. That's normal when running the tank out of gas then refilling it (there will be some air bubbles until the gas fills the line. If you fil the tank to the top you will notice it will perform properly but when its gets below the tube it will start to **** air until it stalls the motor

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

Diagram fuel lines tank primer carbutor poulan pro weedeater


I have no diagram but here are the instructions on how it goes.
The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

Replaced gas tank and primer bulb on my Poulan Leafblower FL1500 and it appears I'm not getting gas into the carb. Any ideas as to what my be the cause?


I assume the new tank came with new fuel lines and filter in it.
First be sure you have all the lines hooked up correctly. There should be a main line from the tank ( has the fuel line on the end of it in the tank) to the fuel pump side of the carb. Then there should be a line leaving the metering side of the carb to the primer bulb then from the primer bulb returning to the tank. When you press the primer bulb you should see it **** the fuel into the carb then from the carb into the primer bulb then back into the tank.
If the fuel lines are all hooked up correctly then you should rebuild the carb.

  • The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
  • If the saw is equipped with a primer, the output line from the carburetor connects to the suction side of the primer bulb (once bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb refills).
  • The pressure side of the primer returns any excess fuel to the tank as it is depressed.

How to hook up a carburator on a weedeater with a primer bulb


Typical fuel line routing2.gif is:

One line (the one with the fuel filter in the end of it) comes out of the fuel tank2.gif and goes to the bottom fitting on the carburator. The second line comes out of the tank and goes to the bottom fitting on the primer bulb. The third section of line goes from the top fitting on primer bulb to top fitting on the carburator. Hope this helped and best wishes.
