Poulan & Craftsman Chainsaw fuel lines 

I’ve looked at ALL the RU-vid chainsaw fuel line changing videos and This the First one explained everything I needed to clarify about what line go to which Nipples!!! THANKS!!!

CLEAR and CONCISE and CORRECT! HOO-RAH! Most of the Poulan chainsaw vids on fuel lines are either ego-trips for presenters or WRONG on line location. Thanky!

I am four score and one year old. And at best, I'm a weekend warrior mechanic. I recently spent a good day and a half, on-line, trying to find out how my model 2375 Poulon chain saw fuel lines were routed. Finally, after viewing your video, I am ready to tackle my repair and hopefully get my chain saw running again. Thanks a million.

Congrats you nailed the Poulan routing. So many wrong RU-vid vids got it wrong. The primer bulb has two different size nipples. The larger is labeled TANK and is more centered than the other labeled CARB which is closer to the screw hole. The filter goes on the small diameter line on the hole closest to the filler cap. The return line (larger) dia. hose goes to the farthest hole from fuel filler cap and had a small union fitting inside to prevent pulling it out. . The lines to carb depend on the model so right and left won’t help. The diameter of the fittings on the carb MAY match. Generally the top is feed and the lower the return to the tank. The primer assembly is past the carb. If you prime and see fuel squirting in the carb...it’s wrong. I have a Poulan 2150 woodsman. The top came from the tank, the bottom to the primer bulb. Thanks for the video.

Thanks, when I pulled the cover off my chainsaw, the fuel lines were crumbled laying in the bottom. It had been in the garage for about 10 years. I needed to know the routing on these lines, thanks again.

Wanted to thank you for this video. Between yours & another I was able to get my father-in-law's Poulan back up & running again.

Thanks for the video. With three lines coming and going, you gave me exactly what I needed. Noting the specific connections on the bulb was EXTREMELY important. Thanks again. Now I'll go back to the garage and get to work.

Thank you for providing this much detail. I have a Poulin 2150, the routing is identical to this video. The only thing that I would add is don't make the same mistake that I did, I bought a generic replacement kit that had two 1' lines. The thicker one has an interior dimension of 3/32" and an outside dimension of 3/16" and is correct. The thinner one is an interior dimension of 1/16" and an outside dimension of 1/8" and was too thin. I found out from another video that the correct line into the tank has an interior dimension of .080" and an outside dimension of .140. I bought a foot of it at the local Small Engine repair shop for under $2.00. It's a tight fit to get the filter on, I had to use a Heat Gun for a few seconds on low. I'm sure that if I'd bought both pieces from the shop that it would have been about half the price of the kit.

Thank you so much for this video. With the layout and configurations presented in this video I was able to change out the three fuel/purge lines between the primer bulb, carburetor, and fuel tank on my PP220. I appreciate the detail presented in this video. It helped me get my chainsaw working again!

Thanks for making this video, I was able to replace all my fuel lines on my Poulan Wild Thing 2375 so i can help with clean up from Hurricane IRMA. Many other videos do not capture and explain the fuel line routes, TO/FROM as well as you did. Thank you!

Thank you very much for this video! It really helped me a lot because all of my fuel lines were rotted and I have never had a chainsaw with 3 different gas lines. Again, great video and great job on the instructions that you gave for the fuel lines.

Best help i got was from you! Had them routed wrong. They were all broke off when started. Thanks from Dennis

The best explanation of poulan fuel lines out there /cleared things up for me,thanx

Thanks for the video,I switched up the line from tank to carb with the line from the primer because the filter barely fits the line to the carb,all straight now,runs great!

This was an awesome video. My lines in the tank had disintegrated. I didn't know which one was which. I put it all back together with new lines and it fired right up. thanks for the great video.

Many thanks for the excellent video. The fuel filter hose inside the tank on my Craftsman 18" saw broke off from deterioration over the years and I mistakenly connected a short piece of new hose (with filter attached) to the "nipple" on the end of the hose coming from the primer bulb, which of course was wrong! So after it not starting I searched the internet on the topic and found your video which set me straight. Replaced the fuel line from the carb into the tank (with filter on the end) and all is good again. BTW, I figured out that the short nipple on the primer bulb (one that connects to the carb) is the suction side, and the long nipple (that connects back into the tank) is the discharge side. Just put your finger over the short nipple and squeeze the bulb and you will feel the suction. So I believe the mechanics of this is that when you push the primer bulb it sucks gas in from the tank, the gas flows through the carb (thus priming it), and the excess gas is discharged back into the tank. You probably already knew all that but this may be helpful for others in understanding how the primer bulb works. Again, thanks for the great video.

Great vid, you've done the best job so far showing the fuel line rout on a poulan . thanks. With this info I feel I can do this.

Thanks 4 the video ! all my lines were rotten and fell off did not know how they were routed but your video helped me out thank a million ! 😄👍👍👍

Just repeat this in your head as you run back to the garage to complete the repair. Fuel filter -> sm dia hose -> Sm Connection on Carb, LG connection on Carb -> LG dia hose -> small port on Purge valve, LG port on Purge valve -> LG dia hose -> Back into tank

Thanks so much man, tore apart a chainsaw and couldn't figure out where the lines went. Turns out the lines were put on wrong when I took it apart lol. No fuel filter to be found on this chainsaw, gonna have to get one.

That was my question, of course. I replaced the fuel lines the way I figured they should go, but didn't notice the second inlet on the carb, which is on the OTHER side of a 2375 (amazing how much difference between models with the same number), but lower. I also didn't notice the second hole for the fuel tank until after I watched this video. Most people with this problem don't realize that it is ethanol in the fuel that destroyed these fuel lines (try it - you can put certain types of plastic in ethanol and watch it crack in front of your eyes). It irks me that Congress ordered this and nobody bothered to tell people that ethanol would destroy many of our lawn mowers, edgers, chain saws, boat motors, etc. The new fuel lines should be ethanol-resistant. Oh, to get the fuel lines through the fuel tank holes, I cut them at a sharp angle, feed it through until I can grab it with long needle-nose pliers, then rotate the pliers to make the hose wrap around them, which pulls it through. Thanks for the info - I couldn't find it elsewhere.

Thanks Brother that was exactly what I needed to know to get my chainsaw running.

Hi sblg43, Very nicely done video! This well help me to repair my Poulan, Wood Shark, Model 1950. Thank You!

Very helpful. Simple, which is what I needed.

Thank you a heap! Got mine and saved lots of money

Great, clear explanation. Thanks for the informative video

Lol I'v run just about evry type of chainsaw and they are all great when they are runnin just like a car. But doing your own service is really a test of patience and as rates go up my patience gets better and better. Thanks a lot for your time and it would be perfect if you mentioned the factory carb settings of 1 1/2 turns out from dead stop in . normally.

Hi, I cant take the trigger to the carburator, I have a pouland 2250 and the line trigger go all arround (left to right) to the carb with the plastic air filter to.. nice video to!

You try to buy a replacement carb from ebay or amazon and they are different and will not fit unless the air box is replaced also. The fuel lines on the new ones interfere with the throttle also as they are on opposite sides and must be modified. PIA.

thanks for the video . Now i could do mine.

Thanks. Great tutorial and very clear video.

Would having a filter on both lines into the tank mess it up? I now realize really only the feed line would need a filter correct?

This was very helpful to me. Thanks

Very good, thanks

I have 2 Poulan Pro 42CC and a WoodShark chainsaws and need to replace all of their fuel lines. Thanks to youtube, I'm seeing that oddly to me, the supply line from the tank (with the filter) is actually the smallest diameter fuel line, and the return line from the primer bulb, back to the tank is slightly larger in the ID diameter for some reason. I'd of bet it was the other way around, but that's not from what I found. I can't find the proper, smaller sized line locally anywhere, and I'm very tempted to simply drill out the hole in the tank a bit, and use the line I have found. I'm guessing Poulan's design engineers are way smarter than me for sure, so they must have their reasons for making the saws as they do. Why do you think these Poulan's even need to have 2 different sizes of fuel lines in the first place, and maybe more importantly, why do you think the supply line is the smaller of the lines? Thanks for your thoughts. Dave

Thanks for info guy! Helped a lot!

Hello sir ! Very informative video. I've purchased a Poulan 2050 2.0 from someone and replaced fuel lines and primer bulb. The old primer bulb just shattered like glass from sitting in a garage so long. My problem is as follows. I press the primer bulb and it doesn't seem to fill with gasoline no matter how long I press it. Isn't it supposed to be full of fuel to start ? The saw won't start. Could this be an indication there is some blockage in the carb itself ? From what I can make out from various diagrams, fuel first goes thru the carb THEN to the bulb. By the way, no blockages NOR kinks in any line.

Q: on my Craftsman chainsaw there was a little clear tube inside the yellow tube. Do I need that little clear tube because now it seems there's not enough vacuum and a chainsaw doesn't run more than a couple seconds unless I keep priming it

My chainsaw had the filter on the large line in the tank from the factory. Every video I watch on this saw seems to show the filter on the small fuel line. The saw in your video is just like mine. Anyway you can share which line the fuel filter is on on that saw? Having high speed fuel starvation problems even with new fuel lines.

Great video, thanks

Very informative. I have one question. On the large line that has the nipple into the tank, how far down in the tank should the line go?

My primer bulb was cracked and when I went to replace noticed all fuel lines were brittle and cracking. Have a two questions: 1. Does the primer bulb use 2 different size fuel lines? 2. How do you install the primerbulb line to the tank does it just connect to a fitting that has another line that goes into the fuel or what?

is the hose going from the primer to the tank the thick one or the thinner one?

Thanks for the help!

Thanks for the help!!

Thanks for the video. Just got mine out of storage and all the line were disintegrated. had no idea where they went.

thanks. this is very helpful.

I am looking for a motor for a weed eater it's a poulan pro link Pp33o 33 cc gas trimmer thank you

My Poulan Woodshark's gas cap binds and unless I use a wrench to tighten it leaks gas on the floor or in may car. I was told that this is common for a Poulan and that replacing the cap would not help. Do you have a solution?

Tank's i now I know how the lines go

Always pull the muffler first or get a comp gauge.

Do you know how to open the handle to replace the trigger on the poulan?

U can make all the fuel lines the same by drilling out the tank where the small line goes in its plastic no problem.

You need to slow down when explaining what lines go where played 3 times. Thanks plus noticed there are carbs that have connections on opposite ends. Thanks god I have the one you are showing with connections on site side of carb.

Again no video on RU-vid has the fuel line location. Where does the fuel line go on the nipple they r different sized

Mufflers are off by a mm from one puoloun to a nother.

A+

ok so i change fuel filter.air filter.spark plug put nwe gas in..runs for a few sec, n diesi, is it time to buy a new one already?? model p3816

Thanks!

i have the same chainsaw. how can i know what size fuel lines to buy for it. thank you for your vids, they are very helpful.

I replaced my fuel lines with copper tubing used in HVAC metering devices. I never have to change my fuel lines again.

Right side.

This sucks! I have a poulan pro335 that has no primer. Old school choke. Not one video for that old beast. Thing is I have a fuel line going into carb and intake? What's what? Hate to trash it when it's right it's a cutting machine.
