On my craftsman gas edger, the fuel tank has 2 holes on bottom, my fuel lines broke. i bought new lines but how do you install the lines do you put a fuel line in each hole or do you use tine same line and fish line into other hole? thanks ken

The fuel pickup should lie in the bottom of the tank. It is weighted so that it will fall to the bottom of the tank when you turn the trimmer back and forth. The line should fit snugly through the hole in the tank so fuel does not spill out when the trimmer is turned up on its side.

You can find replacement fuel lines and filters here - PartsBuggy Fuel Line & Parts.

The smaller of the (2) lines will go to the in-tank fuel filter/weight. Depending on the model, the line will attach to the filter with about 2.5-3.0 inches of additional fuel line within the fuel tank.

The larger fuel line is the return line and needs to go into the fuel tank about 1/4 inch or so.

You should have both size holes at the bottom of the fuel tank to accommodate. Insure you are using the correct fuel line as a complete seal is necessary due to slight pressurization and to prevent leakage.

Use new fuel line. There should be two things (besides fuel line) in the fuel tank. The small line has a (1) fuel filter attached and is routed to the lower outlet on the carb. This is the fuel supply line. Make sure there are a few inches of it inside the tank. (say enough to reach other side of tank). The larger line should have a (2) nylon connector inside the tank holding it. The connector stays right at the tank hole. That larger line goes to the closest outlet on the purge bulb. The other fitting on the purge bulb should have a larger line that connects to the upper fitting on the carb.
Feed enough length of fuel line thru tank holes to pull them out where cap is to put on the filter and nylon connector...then pull them back thru. WD-40 will aid in this procedure or any light oil.

The larger line is the fuel return line from the purge bulb and should have the nylon connector (funnel thing) on it holding it in place inside the tank so the line won't pull out.The smaller diameter fuel tank line goes from the tank to the lower pipe fitting on the carburetor (fuel intake line). This line has a weighted fuel filter inside the tank on it.
New fuel lines are recommended every so often as the ethanol added to our gas nowadays wreaks havoc on the lines and carburetor as well. Get new lines...cut them long....feed them thru holes in fuel tank...grab with tweezers or needle-nose pliars....put on either the fuel filter or the nylon retaining nipple and pull the one with nipple down to bottom of tank...one with fuel filter can stay long to help draw fuel in the tank (yes, it moves around and is supposed to).

you hook one line to it the return line inside the tank

The line you used as a return line pull it back thru the gas cap hole and put that piece on one end of that line and pull it back in the tank until it stops and then hook the return line back where it belongs

Best Poulan Engine Match (probably real manufacturer):

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.

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

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.

Take your old line to a lawn mower parts store, ask for a new gas line of the same size. I would buy about a foot long. Push the line in the tank down into the tank(doing this with the tank empty), remove gas cap, turn upside down, a filter and your old line will fall out. Press the new gas line through the hole, push enough through that it comes out of the filler hole, place filter onto the new line, drop into tank, cut off excess and reattach to the carburator.

The longest, and sometimes smaller in diameter of the two fuel lines, goes from the carburetor to the bottom of the tank. Leave enough slack in this line so that the filter that attaches to the end will rest comfortably at the bottom of the tank.

The other fuel line goes from the primer bulb to just inside the tank, (about an inch). make sure that you get the right size fuel lines. The plastic coupling goes on the end of this line, inside the tank. This keeps the line from pulling out of the tank.

(HINT): When feeding the lines through the tank holes, cut the lines at an angle. They will feed much easier into the holes. You can than cut them off square, once you know that you have enough to work with.

If you need further assistance, just let me know.

1st get new line. find where it goes on carb. pull the line out of the tank .cut a pc. of new line longer then what you need ,cut the end of the tubing with dia.pliers at a long angle then push it into the tank untill you can fish it out hook it back to the filter pull the extra tubing back towards the carb. leaving the filter at the bottom of the tank
