Why does gas bulb collape and does not fill up and which gas line goes to which nipple on carbuerator?


The line with the filter should go to the carb, then from carb to suck side of primer and return to tank from the blow side of primer.

not sure if this will apply to your situation but is just what ive gleaned from experience

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.

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

Need to know how to connect the gas lines from the primer bulb to the carburetor on a poulan woodshark model 1950 chainsaw


The lines should be connected to push fuel into the carburetor. The output (overflow) of the carb is routed back into the tank. So, two lines in the tank, one is an overflow (return) and the other is the suction. On the primer one line from the tank and the other to the carb. Connect so as to "push" fuel into the carb when the primer bulb is pushed.

I need to replace fuel lines and rebuild carb on


Try this for the manual: http://lawnandgarden.manualsonline.com/search.html?q=+mcculloch+corporation+mcculloch+corporation&s=gg314159

If that doesn't help:

Fuel Line Instillation: The longest, and sometimes smaller in diameter of the two fuel lines, goes fromthe carburetor to the bottom of the tank. Leave enough slack in thisline so that the filter that attaches to the end will rest comfortably at the bottom of the tank.

Theotherfuel line goes from the primer bulb to just inside the tank,(about an inch). Make sure that you get the right size fuel lines. Theplastic coupling goes on the end of this line, inside the tank. Thiskeeps the line from pulling out of the tank.

(HINT): When feeding the lines through the tank holes, cut the lines at anangle. They will feed much easier into the holes. You can than cut themoff square, once you know that you have enough to work with.

Carburetor Rebuild: Check the fuel lines for cracks/breaks. If they are o.k., then:
You willneed to disassemble the carburetor and spray with carb.cleaner. Make surethe small screen is free of debris. (Should be able to see daylightthrough it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152), to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance on:

Just let me know.

I have an echo C8 345 that will not run more than 5 secs. when you push the primer bulb and fill the carb, it will run until that is used up and quit. i took the fuel line off at the carb and gas runs out...


If pushing the bulb feeds fuel to the carburetor it isn't conneced properly.

  1. The filtered hose from the fuel tank connects directly to the carburetor input connection.
  2. 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 reinflates).
  3. The pressure side of the primer returns any excess fuel to the tank as it is depressed.

Poulan chainsaw gas line routing?


There ARE two holes in the tank. One samll and another larger. One is on the left side and the other is on the right. Look carefully and you'll find them. As far as connections of the fuel lines:

The line from the fuel filter in the tank goes directly through the small hole in the tank to the top nipple on the carb thus giving the carb a constant supply of fuel when running. The primer bulb is used only for "priming" and does not play a part in the fuel flow after that function. The bottom nipple on then carb then goes back to the nipple on the primer bulb which is clearly marked "Carb". The above connections are made with the smaller diameter tubing. From the primer bulb, marked "Tank", the larger diameter tubing is routed to the large hole in the tank. The tubing goes into the tank only 1/2 to 3/4 inch. As far as getting the tubing through the holes in the tank, cutting the tubing at a slant. But no matter what you do it is still a witch. Be patient, use some Vaseline and avoid the temptation to get out the drill and **** the hole to a larger size.

Fuel filter in gas tank is attach to hose and connect to ?


The longest, and sometimes smaller in diameter of the two fuel lines, goes from the carburetor to the bottom of the tank. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.

The other fuel line goes from the primer bulb to just inside the tank, (about an inch). make sure that you get the right size fuel lines. The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank.

(HINT): When feeding the lines through the tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.

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.
