Experienced gardeners share their insights in answering this question :
The brass fitting on the carb closest to the primer/purge bulb has a line on it that takes old fuel/air inside the carb and sends it TO the fuel tank. So it is routed straight to the tank. The lower brass fitting on the carb (side with vent hole in cover) has a line that goes directly to the fuel tank and has the in-tank fuel filter on it’s end. To insert the main one that gets the filter on its end into the fuel tank, slice a notch out of the end of it so you can squeeze it into the hole in the tank. You can then twist and push it until enough of it goes in to grasp ahold of it with long tweezers or needle-nose pliars. Start off with about 1 foot of Tygon fuel line so you can do this. After you get ahold of it, pull it up thru the fill hole and attatch the filter. Then let it lay it the tank so it will move side to side on the bottom. With the extra line coming out of the tank (it seals the hole) see how much you need to reach the intake fitting on the carb (side with vent hole in cover). Cut it off and attatch it . The other line by the bulb only needs to enter the fuel tank about 1/2 inch or so and it also will seal the hole it goes through. You can notch it as well to help get it started into the fuel tank. This line will be short. I recommend you use NEW Tygon fuel line. I also recommend you get a new primer/purge bulb when you replace the fuel lines. It will deteriorate very soon, ask me how I know! They might have a fuel line kit with the filter, lines and bulb for your machine at Home Depot. Ebay has kits I know. Or you can go to the small engine repair shop and get exactly what you need.

The (clear) fuel intake line runs from the top of the carburetor (straight nipple) and goes to the short post on the back of the primer bulb. The return line (blue) comes from the long post on the back of the primer bulb and goes into the bottom of the fuel tank.
Fixed head systems use individual lengths of line that are loaded or threaded into the trimmer one at a time as needed. This avoids some of the hassles of winding line onto trimmer heads and makes the overall process of dealing with trimmer line less cumbersome.

Which fuel line “port/inlet” on the Walbro wt-380 goes to the fuel tank? It’s on a Craftsman 25cc Gas “Weed Wacker” Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer bulb. The carb has two inlets for attaching fuel lines – one to gas tank, one to primer bulb. One inlet is on diaphragm side of carb (side with the two Low/High speed adjustment screws). Other inlet is on “reservoir?” side (side with air/fuel mixture screw). Which inlet gets the “fuel tank line”? (Other will obviously go to primer bulb. I found all kinds of diagrams on web but none that showed this. Your assistance is greatly appreciated. (Problem occurs when replacing gas lines and forget which line goes where:)
Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does

Sounds like you have dirt/debris in your carburetor jets,fuel passages or a diaphgram that is becoming non-flexible.Be sure to check your fuel tank for water and dirt/debris, if there is water/debris then you need to clean your tank.Also check you fuel lines condition after a while they will degrade and need replacment.If you do replace your fuel lines be sure to draw on a piece of paper the routing of the fuel lines for later attachment to the correct connection.
Make sure you are getting spark at the spark plug, to do this:Remove your spark plug and check to be sure you are getting fire at the spark plug.You do this by grounding the plug on the head of the engine and pulling the crank rope, if you are getting spark then:Check/Clean/Replace your fuel filter if you have one, normally they are located in the fuel tank of weedeaters.Also 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.Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.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.Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.Sometimes you can get by with priming the carburetor or 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.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.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 orginal position before you started.Once you have your carburetor rebuilt that should solve your problem.

How to get new plastic fuel lines in fuel tank in my weed-eater hedge trimmer. the line is larger than the hole in the tank.
Oftentimes it helps to use scissors to trim back a portion of the new line. Start at the bottom and cut upwards at an angle. Put some lubricant (WD40, perhaps) on the line and slide the sharp point into the fuel tank. Using needle nose pliers, grab the line and pull it through. This will only work if you have the correct size line. If the new line you are using is too large, you probably can’t pull it through.
