How to Replace Fuel Lines on Two Cycle/Two Stroke Engines

[@flyingant2557]

Took me two days working on the fuel lines trying to figure out where those hoses went. Thanks for video. Your description is slow, but it's 100 times better than the others I watched. The others made me more and more frustrated. Especially the shaky videos and lacking description. Thanks so much!

[@rickgrayson8562]

I went to the local home improvement center for answers; no one had a clue on how to hook up the hoses. I took a weedeater off the rack and shined my cell phone light in the inner workings and saw how the remote prime was hooked up. But this video showed me how to test the lines for correct placement. Many Thanks

[@johndost2235]

This was the best video showing how to connect fuel lines to the correct component. All others left me guessing. Thanks guys, good job!

[@patrickthesier9314]

This video was gangbusters! I looked at many other videos that purported to show the fuel line routing but none of them did. This video showed how to figure it out on any two-stroke which is a lot like teaching a man to fish. I quickly determined the correct routing and my saw started right up. Thanks much. Now I'm going fishing.

[@markdickson2150]

This was immensely helpful! I have been looking everywhere for fuel line diagrams for my string trimmer, but watching your video shows me how I can figure out the right configuration for any motor. Thank you!

[@freddarrow7057]

Big help! Tried repair clinic site where I purchased my fuel tank but no luck but they did lead me to KZbin but when I searched KZbin I found this vid and it was just the trick! Thank you.

[@nathanielbrown3242]

Great video demonstration outstanding method of explaining the steps to preform and what results to look for. Thanks for being so through.

[@AltonRowell-gb1lb]

Great video. Thanks for the help. I have a poulan pole saw I just replaced the fuel lines on. And I had the fuel lines reversed. Again thanks a million.

[@levi501ish]

I figured it out on my own when my hoses on a little tiller I have gave out due to dry rot. I fixed it with new hoses on the fly, with out removing carb. Watching your video helped explain more what I did and why. Thanks.

[@NewWarOrder]

Just watched this last night to gather info before I disassemble my carb system. I noticed that the fuel lines have been on the wrong side for awhile. I had someone fix my trimmer in the past so either they messed up or the manufacture did. Thanks for the info.

[@michaeltrask7744]

FINALLY,, a truly instructive video on this subject.I will START with your instructions next time.

[@ducdao5763]

I followed your instructions and it worked for me. I was sent my trimmer for repair but they wanted to charge too much money. Now, I fixed it by myself. I just had to order new. gas lines and prime bulb and cleaned out my carb. Simple but it helpful video. Thank you very much.

[@timarcher5141]

Excellent tutorial Mark...just the video I've been looking for, Straight forward English and well thought through.

[@benbarden4079]

I had a problem after I rebuilt the carburetor on my leaf blower. The fuel pump would not pump. After the explanation I realized my mistake and switched the fuel lines which fixed the problem. The explanation was very good. This video is great!! Thanks!!

[@davidmusick3544]

Thank you for ending my several week ordeal. My saw sat in a metal building (Texas heat) for years. All the lines had broke off and were so brittle they would crush when touched.... Many videos show information but my problem was that most videos I had watched before this was that the had both lines on the same side of the carb. Mine has one on each side and no one explained the flow of fuel. You did a hell of a quick explaination. Wife was ready for me to trash it , buy a new one and get some work done. I guess the days of staring at it and drinking a cold one are over. Many , many Thanks

[@marcelhorst4437]

Thanks Mark. Just £10 for a new fuel filter, 2 fuel lines and a primer bulb to repair my 15 year old McCullock Trim Mac 210 strimmer that the supplier/maintainer told me was beyond repair. Good old Google saved me £90 again :)

[@xxxxxpalmtreexxxxx]

Hello Marcel Horst. do you mind me asking you where you purchased those items above... since i need them myself.

[@rickgrayson8562]

This video was extremely helpful for I am just now dealing with a remote prime for the first time.

[@scottwashington4104]

That was very well done easy to understand and very informative. Thanks

[@kennethhiggs6177]

An excellent piece of work, clear and concise..thank you!! Ken

[@breid1966]

I have replaced no telling how many fuel lines on 2 cycle engines and almost ALWAYS forget which goes where! Thanks for sharing this!

[@leehavener8088]

Mark: your tips on how to decide how the fuel lines were properly routed. Your tricks made it very easy to correctly attach the new lines. I also appreciated how you should put new lines in through the tank. Without cutting the lines it would have taken forever to get the new lines into the tanks. Thank you so much... It made the jo easy.

[@veraford8661]

Thank you, this was exactly the information that I needed. I really appreciate it.

[@Smalltechguy]

As always a great simple video instruction. I'm in the middle of a project and seem never to draw a schematic of the way the lines are supposed to be...thanks

[@weldingmomma]

By the way, I thought you should know I bought all my replacement parts from eReplacementParts.com BEFORE I ever knew you have instructional videos! LOL! Thanks sooooo much for the instruction. Greatly appreciated!

[@barthglennh]

Nice job, very well explained and demonstrated.

[@rksmith3862]

Excellent video...the best I found on replacing fuel lines on 2-cycle engines. Question: Does the return line need to be submerged in fuel or can it be above the fuel? Thank you very much!

[@fscii71]

Got a $10 chainsaw (Mcculloch) that didn't run. Opened her up and saw rotted fuel lines. Replaced them and oil line, cleaned out the carb and couldn't get fuel moving. Realized I may have screwed up the fuel line ordering. Watched this video just now, ran down and did the test in a bowl of fuel - booom got the chainsaw running - thanks!

[@martiwf0]

This was very helpful. Next time I replace my tubing, I'll make notes of what went where to begin with. Thanks for taking the time to post this.

[@johngomez4562]

Mark this is great to know, I am learning a lot on 2 stroke carburetor.

[@barsan22]

Thank you very much for posting this very informative video. I am replacing the fuel lines on my Mantis tiller but I did not pay attention on how the old ones were run and I was doubting on doing it correctly. You showed on simple manner how to find which way is correct. I saw another video that was done with goo intention, but it was badly done. Thank you again.

[@hertelfrank]

Nicely presented-- Your video saved the day. As a side note, it appears that my unit came from the factory with the lines incorrectly installed. Although it would run (if you could get it started), your video led me to connect the fuel lines correctly. With a minor adjustment of the carb, all is now good. Have you considered a video on how to remove the protective caps from the carb screws? It can be done without breaking them, but some finese is required. Thank you again!

[@everettesfit]

after dealing with dry rot fuel lines on a 2 year old blower. you definitely helped solve my problem on the restart. Thanks

[@jamestee007]

very helpful & good to see some practical 'hands on ' kind of video ..thanks for posting

[@petebaumgartner8238]

Simple Visual Explanation without getting to technical.

[@davedangerous]

Great presentation... You give a very good flow of how the primer bulb works.

[@GDguitarplayer]

WOW! Thanks to this video and the one on rebuilding a carburetor I got my Poulan Pro trimmer well on the way to running like it should. I had to order one of your rebuild kits and a splined carburetor adjustment tool (that I've needed for about a year now- lol) Thank You VERY MUCH Mark! Great videos!

[@jfrracing1]

good informative video. i wasn't aware that the primer bulb didn't push fuel into the carburetor. i thought it pushed it in. now i know it doesn't. great video!!!!!

[@donc4054]

thanks for the no nonsense video series.To the point,and very helpful

[@theItsMEEjasonSHOW]

Best lesson about 2 stroke carburetors I've come across!

[@oswaldmazzetta396]

Great Post. I appreciate this very much. Professional presentation. I will be a new customer. Oz Mazzetta

[@BoPettersson]

Very informative video, it will help me, i am sure. My trimmer is a 4 stroke but the carburetor and bulb looks the same so I will try to reroute my lines now. My trimmer just starts and then dies until I pump the bulb again. It repeats itself like that but never continues to run. I must have mixed up the fuel lines when I replaced to a new carburator.

[@mashallahyousefzadeh7912]

Excellent and very professional.

[@FIXTechGuides]

@bosstweed429 The return line does not need to be submerged. It sounds like you are having some issues with a carburetor that is dirty or the internal components have deteriorated. Take a look at our videos titled "How to Rebuild a Two Cycle/Two Stroke Engine Carburetor" and "How to Clean a Two-Cycle/Two-Stroke Engine Carburetor". I hope this helps, -Mark

[@MyGarageWorkshop]

Mark, thank you very much. This was very helpful and explained it all perfectly. Very well made.

[@FIXTechGuides]

Cut the end of the fuel line at a sharp angle. This will make the line much easier to insert. Hemostats also are very helpful if working in a tight space. I hope this helps, -Mark

[@doodoode]

This was very helpful with such a simple device. I was trying to push fuel instead of pull. THANKS!

[@Caseycallender]

Very good video, exact same carb that was on my Ryobi, very helpful thanks.

[@nongja26]

I really like how u presented ur method...simple and very clear...thanks...

[@spenegdt]

Very helpful! I was looking for this exact explanation. Great video.

[@gwsswg]

VERY WELL EXPLAINED IN PLAIN ENGISH,WELL DONE

[@johnfilip]

Thanks for the great video. Have several old 2 cycle engines. Was able to rebuild carbs with ease.

[@He-Him373]

Thank you for actually explaining that the fuel needs to be drawn through the carb rather than pushed into it. I now know why diaphragms get busted. The pressure of you forcing the gas against the check flap the wrong way years it.

[@TheBadbrad9]

Thank you, have watched several of your videos now and very well done.

[@Snowdogkh]

The EXACT video I was looking for! When will I learn to draw a diagram before I rip everything all apart and then wait a week before I put it back together after ordering new parts! Excellent video and well done! Thanks!!!

[@peediemo]

Thanks that was very helpful,now I understand how the fuel should flow,,thanks jack

[@liberty5217]

I have a troy bolt string trimmer tb20cs. I put a new primer bulb on it, New fuel filter & line. I believe hoses are correct. I watched your video 5 or 6 times, it's the best. I connected the supply line to the carb, pumped the bulb and fuel runs out everywhere. Put it together and it runs,but only for 15 to 20 seconds and the supply line is dry? What's up? Thank you Chris Jones

[@steveshlacker]

Awesome! I got my $5 yardsale weed-eater running thanks to this vid :) Great job, very clear and easy to understand. Excellent how-to vid!

[@Thomas-ck1tm]

very clear explanations...was wondering why my primer button was staying depressed now i realize i had it lines backwards....thank you for the video....saving me lots of headache and maybe a trip to the shop..... :)

[@mbhistand]

logically presented and fool proof.

[@dustydemiah]

Most helpfull video so far. Thanks.

[@dondelotto3750]

enjoyed learning a proper way of doing the repair . DD

[@danielbrasier9069]

This clears up a lot for me, now it's clear to what line goes where. I always thought the primer was the fuel pick-up, Thanks for the information.

[@sitcomsid]

Excellent teaching qualities thank you

[@LNichols429]

Very detailed explaination, very helpful.

[@verndangel4433]

Mark, that was great. R all primer bulbs the same? Since I replace many I always uses the outside connector on the primer bulb. That seems to work. Thanks again for a great video.

[@yonnieo1]

Thanks Mark. Great help.

[@weldingmomma]

QUESTION: Hi, Since you didn't actually install the lines into a Weed Eater fuel tank, this leaves me with the unanswered question whether the return line must be long enough to stay submerged in the fuel OR, does it simply have to reach the tank to dump the fuel back to the tank? I did everything else correctly, still not working. Thanks in advance.

[@123crazyleg]

thanks, I just wish I had seen this video earlier it would have save me a lot of time. Thanks

[@mdkarnish]

Very informative. Thank you.

[@KennyBCF]

Have any tips to get the fuel line inserted into the fuel tank; especially the return from the primer bulb on a Poulan 2150, which is at the back of the tank? Loved the video. Really well done!

[@guero9204]

Thanks a lot helped me fix my chainsaw. Found out I had my lines all wrong. Thanks again.

[@gooutside6055]

Man !!! I wish I could give 100 Thumbs up (likes) for this video. This really helped me

[@madman1124]

another great video mark.

[@FLTHC0214]

After replacing the cracked fuel line, I was sure that I had the correct. Chainsaw ran for a few seconds and died. So I replaced the fuel filter, gas cap and cleaned the spark arrester. same results. Saw your video, rerouted the fuel line and the chainsaw runs like a rapped ape!!! Thanks!

[@keithbailey7855]

Thanks Mark. That really helped out. I feel a lot more confident taking on an upcoming project now.

[@adamgutierrez7208]

Just what I needed. Thanks...Question. When you turn both the Low and High screws in your weedeater al the way down..to start it again how many turns out do each take?

[@FIXTechGuides]

@catman7771 Glad to hear that small engine repair is so easy for some. Thanks for watching!

[@alientrade]

Excellent video, well explained.

[@sidefx996]

FANTASTIC video. Thanks so much!

[@FIXTechGuides]

@steveshlacker That is great to hear! I am glad we where able to help you same some money! -Mark

[@subukai]

Excellent tips! Thanks for creating this video.

[@rsa5500]

Excellent video, thanks!

[@mrjoebbad02]

Very informative, and presented very well also. Thanks

[@fly4doe2]

Yep! Helpful video. Thanks.

[@FIXTechGuides]

@freshn2008 My guess is that you are working on a larger 2-cycle engine such as a snowblower engine. The larger 2-cycle engines will have a carburetor with a bowl. The bowl eliminates the need for the return line. On this type of carb there will be a fuel line feeding the carburetor and usually a single line to a primer. I hope this helps, -Mark

[@youraak]

Excellent, thank you very much for this video. I mistakenly connected primer inlet from the tank and outlet to carburetor. weed eater runs for a few seconds and quits. Now I will connect as you specified and see.

[@bksrecang1413]

Thank you sir! now I will get proper routing the fuel line, I was struggling for 2 days

[@cluelessbeekeeping1322]

Thank you so much for posting this video!

[@michaelgoodier5910]

So simple when it's explained like this, thanks.

[@rbadlon613]

great step by step info.

[@brucelandeg1371]

Thanks Mark. Now, with fuel lines correct, my Husqavarna leaf blower idles just fine, but dies when increasing the throttle. I will try to check for leaks into the carburetor or replace diaphragm.

[@randybarnhart6976]

Thanks...this video helped me out! Very well done. I'm amazed that Walbro does not provide better info in regards to the intake pipes on their carbs. Oh well. Once again, thanks!!!!

[@moostafak]

EXCELLENT THANK YOU...YOU MAKE IT LOOK SIMPLE..

[@donmccormick5629]

Very helpful, fixed the fuel line on my Homelite tiller

[@Chevelle1970SS396]

Very informative video -- nice work.

I just found EERP, love you guys . I found 'spring wires' for my p-c router, fast shipping! thanks!

[@KevinSandersMDGoHokies]

great video. some how my lines got mixed up while replacing the primer bulb and fuel lines and the caborator kept flooding. now all as well.
