Jasmine Stewart: What is the part at the end of the return line inside the fuel tank
actually used for. Some say it is for joining tubes but there has to be
another use for it. Is it to stop the tube from being pulled out of the
Steve Carmichael: Thanks for the helpful video!!! Just what I needed. Replaced the fuel
lines and put it back together, then it fired right up. Awesome!
TheRoyEven: Hello donyboy you are a great man with chainsaws, but i have a quistion to
I am repairing a oleo mac 983 tta concrete saw but one thing is missing and
that is the fuel tank air breather.
Is it possible to use any sort off air breather that wil fitt on the
Greetingz from Norway
Jordan Lott: Can this apply to a craftsman chainsaw?
Aaron Hamilton: Sir the holes seem a tad smaller than the hoses, could we drill the hole a
we bet bigger, or is there a trick to getting them in?
Levkin: 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.
Junior D: Do the fuel lines have to be the same size??...Thanks
George W: Thanks for the helpful information. I got the fuel lines correct, but the
primer bulb is so slow to return. Also noticed some fuel coming out of the
fuel cap. Any ideas?
Trog Lodyte: I saw a couple comments on getting the fuel lines through the tank bulkhead
so I'll share what I learned the hard way. I took a utility/razor knife and
cut the one end length wise on on angle so the very end is much smaller
than the hose I.D.. Once it's sufficiently through that they can be reached
with a thin designed pliers (I used a hemostat and it worked perfectly).
Pull extra through and cut the hose square and install filter or other
fittings as needed. Another thing I didn't do until it was too late that
may be a good idea is to note the length of the original hoses and
duplicate. Thanks for the video.
George W: Just a note. The reason why the primer bulb would be slow to return is
because there was a blockage of the 3/16 screen under the bulb on the
inside of the carb. Cleaned it out and reassembled. Now works fine.
Scott Hansen: I can't even begin to tell you how helpful your videos are. Much
Txsecededave: Thanks, that's exactly what I needed to know. My fuel lines had rotted to
nothing, especially inside the tank, they were mush, so I had to replace
all the lines I had the fuel filter on the wrong line, inside the tank.
In the config I had it in, the chainsaw would run until about half tank,
then die. Now, thanks to your video, it runs and runs. Greatly
jj339c: Thanks for posting. It was a life saver as all my fuel lines were rotten
and I had no idea where they went. penciled a diagram while watching your
video, replaced fuel lines and filter (bought them from Home Depot about
$6.97 for the kit with fuel lines and filter) and chainsaw is running like
a top. Thanks again.
Michael Alwin: man, I was pulling my hair out trying to figure the lines out thanks for
aj glebc: Thanks for the help.
Ed Caraccioli: Very fuzzy video resolution - however I believe the information is sound -
the small hose comes through the left side hole (small) connects via a
small plastic fitting to a filter inside the fuel tank - the hose above
connects to the carb directly right - then the larger hose goes from inside
the fuel tank to the primer bulb (tank) and the smaller hose fitting on the
primer bulb - goes to the other carb fitting intake ? I have had much
difficulty getting these hoses through the holes - even with the wire pull
tool - GOOD LUCK - POULAN 2150 model - (talk about hose jobs)
kirk comiskey: Great help, thanks a million.
Eric Neal: Is the configuration the same for a weedeater?
dixie griffin: very informative
Dave A: Thank you. Thank you. Thank You. I have looked at several videos for
this info and yours was the best by far. My saw is back in commission.
Wayne Chandler: Great Video. It saved me when my fuel line fell apart and were not
connected so that I could see the original configuration
railbuggy: That's a great presentation on the fuel line routing. Too bad he doesn't
show how to fiish the stupid fuel lines through the fuel tank holes. The
engineer that chose the locations of those holes needs his butt kicked!
The suction line is impossible to get at through the fuel cap hole.
Roberto Silos: What about the small connector I found inside the tank, donyboy73 mon? I
assume that goes to the bigger fuel line and is the suction part of the
primer bulb. Question is how long should the line be inside da tank, mon?
railbuggy: .Well after whittling down the tubing to over a 1 inch length the size of a
toothpick I was finally able to get the small diameter fuel suction line
through the hole far enough to grab it with a pair of forceps. Now the
dang line won't stretch over the fuel filter nipple. I tried heating it
with a lighter and it still won't go on. I bought the fuel line from a
Poulan dealer so you'd think they'd know what they're doing. No wonder
people get so pissed off working on chain saws!
Tony Blackwell: Thanks, I had two lines swapped. Now it's alive again. $3.24 and it's
Hunter Dockery: Walls
David Thorne: is the fat line 3/32?
William Silva: I only have a 1/2 of a turn total on my fuel/air screws because of some
plastic limiters mounted on the screws. Can I remove those? My saw appears
to be starving for fuel. Only idles and immediately dies if any amount of
throttle is applied.
Robert Munroe: awesome! I took mine apart to clean it and replace some rotted lines.
Couldn't see where the lines were they were so bad. This is great as I did
have it plumbed incorrectly!
donyboy73: JUST A SLIGHT DIFFERENCE
BCtruck, rebuild, repair,repurpose: I sure could have used some advice a couple days ago. My freind had a
weedeater that had dry rotted fuel lines. I had some major confusion before
I finally figured which side of the primer bulb was suction. Took me half a
day of assembling and disassembling to get the lines right. It was that
afternoon that I subbed your channel. I'm articles and have been for thirty
years,but when I'm to old to drive I hope to make a liitle extra working on
small engines. Love your channel.
donyboy73: a video is always better than a hard to find shop manual,lol
donyboy73: @bradybill1 what is your fuel mixed at?
scubagator2006: donyboy73 - Just the ticket. I picked up a saw today and found the filter
rolling around in the tank. Your video will certainly make the repair
easier. Question - I also found a small nylon fuel line connector in the
tank and it has barbs on both ends. Any thoughts on where it goes? Thanks.
Dnuccio95ZJ: @donyboy73 cool i will thx
f86sabjf: Thanks Donboy73 i tried to start mine and it wouldnt start. I pulled off my
fuel cap and the fuel filter fell out.:) needless to say it would have
never started. There wasnt one comlplete fuel line on it. Your vidieo made
it easy to fix. Thanks Again
cyberian2007: Thank you !!
donyboy73: discontonlineparts com ships to mexico
donyboy73: @pivotboy63 watch my grass trimmer repair videos, there i show proper line
configuration for them
huskysaw89: Thanks this video REALLY helped! I have a craftsman 2.2 same saw and all
the fuel lines were gone I had a hell of a time trying to figure them out
this helped me with all that! Great vid
Patrick Hourihan: I wish I had read your comment first. After hours of frustration (and some
cursing) I was finally able to push enough thru with a piece of baling
wire. I grabbed the end with a clawed pickup tool like you use when working
on cars and drop a part into the engine compartment. Once I pulled it thru
I trimmed the end. I like your way better. When I do the next one in
10-years, I'll have to remember your technique!! Ha ha
Tommy Kaye: how do i put new gas lines in the saw if you could help me that would help
me out a ton
706gallito: Very good video !
Tim Ho: that goes into the fuel cap. the star shaped washer ought to be attached to
a long black plastic piece ending in a large circular shape designed to
allow you to drop the fuel cap to the side of the case as you refuel. It
may well have something to do with the breather function of the cap as a
one way air valve - - I'm still working on that part.
donyboy73: cut the end at a 45 degree angle, it should go in much easier, you can also
lube the end going in the tank
donyboy73: @mogges1 sometimes the bulb needs to be replaced when it won't come back up
mogges: dony do you have any videos on troubleshooting a chains saw
penanoable: GOOD JOB YOU SAVED A LOT OF TROUBLES
f042676: Is the large line on primer bulb the same size as the line from top of carb
to fuel tank filter? Video very helpful. Thanks
