I have a 32cc Craftman Brush wacker trimmer and the fuel line fell apart I need to know how to install the new ones.

Take the primer bulb off and use two new fuel lines and dip them both in fuel. Push the primer bulb to see which side returns the fuel, this is the line that will go from the bulb to the tank, the other line goes to the carb.

Hi pmbaugardne...
Please take time to rate me

Hi glen11234...

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.

Many things to check. Spark, fuel and compression. Check these to narrow it down.

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.

Depending on the brand of line you use, Tygon line is self sealing but seems to shrink faster then factory supplied because of the ethanol in the gas. The stone gas filter is designed to fall to the lowest part of the tank, not stop the line from falling out.

Check the fuel lines for cracks/breaks. If they are o.k., then:

You willneed to disassemble the carburetor and spray with carb.cleaner. Makesure the small screen is free of debris.(Should be able to see daylightthrough it.)

Use a Den Tek Brush, (http://www.drugstore.com/products/prod.asp?pid=165357&catid=1152),to clean the small portals in carb. These portals can become blocked. Reassemble and start.

If the carb. parts are more than 4 years old, you may have to replace them.

If you need further assistance, just let me know.

This can be a little tricky, the filter is in the tank connected to the line. The line is pulled through a hole in the tank which seals only because the line is the correct outter diameter to seal the hole and not collapse the interior. Fuel line and filters are available at most places that carry outdoor power equipment parts but you must make sure the line is the exact size inner and outter as the original.
If the trimmer has a primer bulb the line goes from the tank to the bulb and then to the carburetor, a second line goes from the carburetor back to the tank, don't get them mixed up.

The esiest way to figure it out is to take the line with the filter and put it on one nipple then push on the primer a few times and see if fuel comes out of the other, if no fuel then switch the line over to the other. But if im not mistaken the filter will go to the bottom.
