Fuel Lines

[Step]

Hi. I am sure there is got to be trick to replacing the fuel lines on saw.   I am trying to self teach myself so I can work on my own saws.  Since my shop bills for the last year are getting high. 

I have several saws but  I decided since I have never worked on one much before to start with a Poulan Wildthing that's been seating for a few years of course the lines crumbled right off.   However the new lines are larger than holes going into gas tank and I am not having an easy time getting them into the tank. 

Help advice would be awesome

Welcome to the forum!

Never done a wildthing, but I know on the husky\jreds I've done, they do fit TIGHT.
Try lubing the line with some 2 stroke oil. If you can get it through the tank just enough, you can grab the other end with a pair of long needlenose pliers or foreceps.

Welcome to the F F
Cut the line at a sharp angle starting at the end bought one inch or so it should go in far enough so you can pinch it with a needle nose and pull it into the tank hope this helps

Yeah I am a husqvarna guy really.  I put a line in 142 last year and seem like it went easy.   I have had 3 carburetors rebuilt in the last year on three different saws.  I think total was $180.   I like saws and just here in the last few months decide to do some collecting.  I had the Wildthing for over 10 years and one of the springs broke on the fly wheel and I thought it was the plastic pulley striped out again.  It just been sitting in the shed.   So long story short the Wildthing is my practice test. 

Have you ever heard putting the line in the freezer and it will shrink?

Freezing will not shrink it . It will get stiffer.

Put it in hot water or warm it, it will be more supple.

I have some stiff solid steel wire, maybe 16 gauge. On saws where you cannot get to it with needle nose pliars you can work the wire through the hole in the tank. Cut your line at an angle. Cut a tiny hole in the end. Run your wire through and crimp it real tight. Spray the line with silicone and pull it through.

Hemostats are a must for anyone working on chainsaws. They come in different sizes, curvatures and lengths.

Saws that have a grommet for the tubes usually have bigger holes than the tube. But plain tube without a grommet is  a tight fit in the hole.But this kind of tube usually has some free length to it. Its simple to get then through the hole. Cut the end you want to send through the hole on a deep slant. The slant-cut tube will easily pass through and you will need a soft end nose plier to pull the un-cut portion through. Simple

P.S.
goose63 has already suggested exactly the same thing I see. Well this is just a repeat  :

[ZeroJunk]

On a large Husky where you have to go through the carburetor box and the fuel tank I will already have it pulled through there with a wire while you are trying to split the thing long enough to get to it with needle nose pliers.

Yeah I think this is a must.  I am going to pick some up tomorrow hopefully. 

Hey guys thanks for the reply's and I really like the site.  I been reading and watching.     Pretty kewl.

Wanted to say thanks to everyone.  Cutting the line long ways and using the hemostats got it done.  New primer and fuel lines installed and couple pulls she was up running.   It idle right after cutting a few pieces.  Freaking Poulans they just keep on and on and on. 

I lost a brand new 440 Husqvarna during an ice storm a few weeks ago.   Ice had kept my tailgate from closing good and it a little Poulan made its way out the back while my dumb sat talking on the phone.  Just another reason not talk on the phone and drive.  Never know when your going to loose two good saws out the back of the truck.  I am just glad no one got hurt.   

Thanks this was big boost to my spirit.  Now time work on 235e Husqvarna with carb and fuel line troubles.

I have drilled out the hole in the tank to make the larger outside diameter hose work. also dental floss works good getting the fuel line started. use several half hitch's to keep it from sliding.

Thanks Bush Hog

Just out of interest.      Does the fuel lines have to be air tight leaving the tank.

[Oliver1655]

The above responses of cutting an angle then pulling with hemostats/needle nose pliers or using a wire are on target.

I would not recommend drilling out the hole.  The hole is slightly smaller so once the fuel line is in place it will make a seal with the tank.
