They are different sizes, if you hook them up wrong, it will start but not run so just reverse them. Here is a diagram too: http://media.fotki.com/1_p,sqqwtfdbwqbsdgkxgtqsskgwtqkq,vi/kktggsfswxkkwbrrwgg/1/1303472/5961857/image12549img-or.jpg

SOURCE: try to replace fuel line craftman weedwacker

You will need to get some TYGON fuel line. Match it up to the size of each fuel line, some of these trimmer use two different size lines, and remember which size went on which connection. You will want about a foot of each. Cut one end of each line at a 60 degree angle. With a pair of needle nose pliers, feed the angled end of the fuel line into the hole going into the tank and feed it into the tank untill you can see at the tank fill. You cut the angled end off and put your filter on the line. Pull it back until the filter lays at the bottom of the tank. Hook this line up to the supply side of carburetor. Take the other line and put it in the tank about 1" or 2"
then cut it off to fit on the carburetor. HTH
Good Day.

Hi derekjhope...

Sounds like you have dirt/debris in your caburetor jets,fuel passages or a diaphgram that is becoming non-flexible.
Check/Clean/Replace your Air Filter, a dirty air filter can make your engine run to rich with fuel.
NOTE: Before you disassemble the carburetor:
Mark each piece with a awl, or some kind of instrument that will make an alignment scratch before you disassemble the carburetor into separate pieces.
That way you will know which way it goes back together when you reassemble it.
Sometimes you can get by with priming the carburetor or by using starting fluid and letting it run a few times like that, and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.
Check you fuel line condition after a while they will degrade and need replacment.
Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.
When you remove your fuel lines from the carburetor be sure to make a drawing to how the lines are connected to the carburetor.
Normally the big line will be the line the fuel filter is connected to inside of the tank.The smaller of the two lines is the return to the fuel tank from the carburetor after it is pumped thru the carburetor by the primer bulb.
Make sure you are using fresh fuel...and oil mix if your using a two cycle mower or weedeater with the oil to the right mixture and not too much oil as it can cause hard starting.
If the mower/weedeater is over a couple of years old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
The diaphgram may look good and flexible, but it can be deceiving and not act as a fuel pump as it should because it has become too hard.
When you clean your carburetor, I recommend that you use a laquer thinner type cleaner to clean and dissolve the laquer build-up in the float and needle jet passages.
Be sure to remove all plastic and rubber parts before using the laquer thinner because it can dissolve the plastic parts and render them unuseable.
Be sure to use COMPRESSED AIR to blow out all the fuel and air passages.The higher air pressure is needed to blow some of the trash/debris from the fuel or air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Keep in mind that the float (if you have one) for the carburetor must be level when you go to reassemble the carburetor or follow the instructions you get with the carburetor kit, or you could also ask the parts man that you get your kit from.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their original position before you started.
Once you have your carburetor rebuilt that should solve your problem.

Fuel hose to the gas tank has broken as well as the primer hose has broken


Check age of gas. Cannot be more than 30 days old. Make sure to use fresh gas w/synthetic 2-cycle oil @ 40:1 ratio (1 gal.) Gas to 3.2 oz. Oil). Do not use old or stale oil/gas mixture. Always use the proper oil/gas mix. If you do not, your engine will suffer rapid, permanent damage. May need to clean or replace carburetor, fuel lines, and fuel filter.

Found "parts" (hose, 4 washers, cylinder with hose


What you found is the fuel filter. It has these washers as weights to hold it at the bottom of the tank. The reason it came of is due to old fuel lines. Just replace the fuel lines (One at a time), and replace the fuel filter, available at your local lawn mower shop.

Hope this helps

Fuel Lines - 25cc Craftman weedwacker


Your Craftsman Trimmer/weedwacker:
http://www.searspartsdirect.com/partsdirect/getModel!retrieve.pd?modelNumber=358795591+&pathTaken=partSearch

Best Poulan Engine Match (probably real manufacturer):
http://www.ordertree.com/modelinfo/PWE/BC2400-Gas-Trimmer-Type-6/75.BC2400-Gas-Trimmer-Type-6.1.59.1.html

My decisions are being driven by my experience with Poulan chainsaws. Small hose in tank (long enough to reach all corners), filter on bottom, connects to lowest connection on carburetor. Small hose on upper carburetor connection to small fitting on primer. Large hose from large connection on primer through largest tank hole, roughly mid tank long. nothing on bottom. I suggest you leave the 2 connections on the carburetor long enough they can be swapped (just in case) then try it. if no go swap them.

Typical fuel system and a suggestion or two:
http://www.fixya.com/support/r3706813-2_cycle_fuel_system_repair

This is how I would configure it if a chainsaw, doubtful they would do something completely different. In defense of Jerry, he knows how it should be done, clarity of instruction could use some help. Good Luck. HTH
