Question about Poulan Pro Chain Saw 46cc 20"

1 Answer

Poulan 2175 chainsaw Wild Thing fuel line replacement. I searched the entire internet to find good directions for replacing the fuel lines and was unsatisfied. However, now that I have done it I hope to provide good directions here. First if your lines have not crumbled into unrecognizable pieces then take note of everything. For this job you will need a phillips head screw driver a star head driver, pliers or socket set, scissors and a pair of forceps. Plus you should buy 2 feet of 1/8th inch tubing, 2 feet of 3/32 inch tubing, a new fuel filter and possibly a new Poulan purge/primer bulb. Take off two outer covers, the air filter and the carburetor you will have to detach the carburetor from the throttle wire (take note of how it connects). You will have to unseat both the blue choke and red on/off plastic switches. Turn the saw so the blade is off to your left. Now when you look into the cavity you should two holes going into the fuel tank. The big far one is the return. The little close one is the pickup. Take your bigger tubing and make a tapering cut about two inches long on one end. This gradual taper is the only way to feed the hose into the tight hole. push in the 2 inches of tapered cut and then reach into the tank with the forceps and grab the tubing. Slowly pull the tubing in to the tank and out the cap opening. This may mean you have to grab with the forceps and only pull an inch then regrab. Once you have enough out cut off the taper and put on a very small part that has a washer and a little tapered rubber end. The fuel will reenter the tank through here but the tapered end closes to keep it from reversing. Pull excess tubing back up until about an inch reamins in the tank. Next repeat with the smaller hose and smaller hole. Put the fuel filter on this and leave enough slack in the tank to have the filter move from side to side. Now reinstall the carburetor and connect the little hose to the black plastic upper fitting on the carburetor. Take the remaining small tubing and connect it to the brass carburetor fitting. Run both the small and large tubings under the carburetor toward the purge valve (toward you). The purge value has markings on it and the big fitting says tank and the little fitting says carb. Cut the tubing to a length about an inch longer than it will need. Put the big tube on the big fitting and the little tube on the little fitting. Put everything back together. The tricks in this advice are: the little tubing runs from the tank to the carburetor ( this doesn't seem logical to me) and that the primer is after the carb in the fuel flow ( another illogical thing). Hope this helps. 1/8 inch = 0.125 inches = 3.175 mm; 3/32 inch = 0.09375 inch = 2.38mm

How long should the juel line be on a 40cc poulan


A fuel line should be long enough to teach from where it attaches to the carberator to the fuel tank but not quite touching the bottom - however the line in the tank end should have a small filter on it. You should be able to buy a replacement line for your specific saw.

Poulan 18" Wild Thing Chainsaw. replaced bulb,


Ok lets get the pipes conecterd correctly to start with, the hose comeing from the tank with the filter on the end, connects to the carb fuel inlet nozzel ( the nozzel neares to the pump cover held with one screw ) the pipe coming from the other nozzel on the carb goes to the short nozzel on the primer ( suction ) then the pipe from the longest nozzel on the ptimer goes back to the tank, once you have this correct, try the saw again. Change the filter in the tank, the carb screws will have some type of anti tamper device, this is why you only have a small amount of adjustment, you may need to remove these to adjust the carb properly, if there are any splits or cracks in the fuel lines the saw will not run properly.

TppOn my Poulan Wild Thing 18" chain saw the fuel line appears to have out of the hole going to the gas tank. How do you get the line back through the hole, it is a very tight fit?


Cut the end of the hose off at a steep angle, push it into the hole in the tank, now use a pair of needle nose pliers through the fuel filler hole to grab the end and pull it through.

Fuel line on my Poulan chainsaw broken inside fuel tank


Check the metal fitting located in the top of the fuel tank to see if it can be unscrewed from the upper side. If so, the inner tank line is an easy replacement. You may have to remove the carburetor to access the fitting properly. Be sure to use the proper replacement line and the original length. Check the fuel filter for plugging. Check the rest of the fuel lines for decay or other damage. Make sure the primer bulb is in good condition. Hope this helps!

Model 2175 poulan - pump up primer bulb and it colapses. When i put fuel in head it runs till gone..


Change out the primer bulb and the small gas lines going to carb and primer. One of these has a small crack to let air get by and this is how you get a flat primer bulb. Pick the kit up at lowes for $6-8.

How do I hook up a fuel line to a carbuertor on a Poulan 18 inch?

  • 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 bulb, an output line from the carburetor connects to the suction side of the primer (once the bulb is collapsed it draws fuel from the tank through the carburetor to refill as it inflates).
  • The pressure side of the primer returns displaced fuel to the tank as it is depressed.
Take lots of notes and a few digital photographs to help with reassembly.

The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best; components are listed but on multiple illustrations.

18 inch poulan wildthing doesn't want to start, doesn't seem to be getting fuel.


I suspect your fuel lines have failed, pretty common since use of ethanol in fuels. The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best. It does show components and part numbers. Find it here:

Any fuel containing ethanol is not good with chainsaws. Mix what you expect to use within a few weeks. Anything over 1.5 months old use up in a 4 cycle engine.

Fuel lines have rotted off. need to replace then


Mr Tittle;
It isn't good but it's all there is.
What little fuel system system detail there is can be found here:
Poulan.com

If it is a 2375 WildThing find 2375LE Gas Saw Type ?. The last digit of your serial number should be a -1 or -2, the type.

  • The filtered hose from the fuel tank 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 the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb reinflates).
  • The pressure side of the primer returns any excess fuel to the tank as it is depressed.

Fuel line routing help.


You should have one line (with filter) going to the carb inlet & one line going to the bulb then back to the tank.
