Both lines go back in the fuel tank. There should be two holes right next to each other that the lines go through and they should be fairly snug fitting on the lines to prevent gas from leaking out.

How do i replace fuel lines?


Where do the fuel and primer lines go in Craftsman or Poulan Chainsaw
Hope this helps. Also try to avoid using gasoline with ethanol. This causes the lines to deteriate.

Ryobi Grass Scorpion Petrol lines from tank to primer to carby where to where


Thanks to doityourself.com.

The line off the top of the primer bulb goes to the top of the carburetor.
The line on the bottom of the primer bulb goes to the fitting on the center of the fuel tank and the line off the side of the fuel tank goes to the bottom of the carburetor.

Tip

Easy way to install fuel line and primer bulb return line into gas tank


Chainsaw fuel lines enter the gas tank from holes in top of tank. They are sized for a tight fit to prevent leakage. Make it easy on yourself when pushing the line through the tank by cutting a long lengthwise taper cut with razor knife 3 inches or longer to easily feed through that tight hole. Once started you will then have to grab it through the gas cap hole with needle nose pliers, then cut the tapered end flush and add fuel filter. Readjust inside length by pulling from above, then cut to length to upper carb fitting. If connecting to primer bulb a filter is not required and make sure the line goes to fitting on primer bulb marked tank.

2 fuel lines broke (1 from tank 1 from primer bulb). Line from back of tank to back of carb still there. Which lines go where?


Do not mix them up!! Doing so will bring debris into carburetor. Assuming the line from back of tank to carburetor is the fuel feed line then you should also plan to replace it if the other lines have failed..

The primer bulb sucks (pulls) the air fuel through the carburetor thus venting out any air. The process draws the fuel through the in tank filter through the impulse fuel pump. The fuel connects via an internal carburetor passage from the pump to the needle valve and during the prime passes the needle valve into the pressure diaphragm chamber. From there the fuel is drawn(sucked) into the inlet side of the purge/prime valve and returns the air fuel into the tank.

The center hose on the primer is the return into the fuel tank. The hose from the center of the primer bulb goes directly to the fuel tank and is the return. The outer diameter hose connection to the primer is the connection made to the carburetor. By closing off the end of the hose you can test with your finger the function of each hose. You do not want to pass fuel into the carburetor by reversing the primer hoses.

What would be wrong with my weedeater when i press the primer bulb gas will start to come out of the gas cap ?


You could have a clogged tube from the primer into the carb, but it also sounds like the fuel tank is overfilled.

Ryobi 410 mini tiller w/Walbro WT149A primer bulb won't prime. New bulb, new fuel lines, hooked up right, carb cleaned. Been sitting for several years.Runs when fuel is pumped into the fuel inlet.


hello sir, my machine will only start when pumping primmer bulb or squirting fluid in the carburetor than stops. the fuel line has broken off, in most small carburetors this is a ongoing problem.old fuel will crystallize when left in tank for a long time.plugging up ports, fuel lines, small screen in carburetor.fuel lines will dissolve clogging carb.this is why it will run when the choke is on creating a vacuum to where there is fuel forced in the carb to rum,also the gas will evaporate leaving the oil behind clogging up carb.the thing to do is remove carb. and clean out,replacing gaskets or fuel line if necessary.use carb cleaner to clean out carb.make sure to make note where fuel line go.the fuel filter broke off of fuel line letting debris get in carb plugging it up.the muffler is known to clog up a lot on these machines where they want run. the compression should be 60 to 120 lbs any thing below 60 is junk. when adjusting the carb screws turn in all the way than turnout 1 1/4 turns turn in slow until machine runs also you need to check for spark by removing plug and grounding against engine to check spark, ok.a new spark plug would be a good ideal too , if you are going to make these repairs use new fuel line and filter,hope this helps,any comments welcome,thank you, !!

Gas edger Model 358.773100 the fuel lines were cut. looking for diagram to repair


They don't really have fuel line routing diagrams available. This is even true on the Sears website. What they do have is the machine breakdown diagrams with all the parts listed and pricing for all available parts. I can give you fuel line instructions for a 32cc trimmer. I see that your model is a 24cc 2-stroke engine. This may point you in the right direction.
The small diameter line out of fuel tank (has filter in-tank on end) connects directly to the side of the carburetor that has the fuel pump....that is the cover without the hole in it. Other larger diameter fuel line out of tank connects to the longer nipple on the external purge/primer bulb. The bulb "pulls" fresh fuel from the fuel tank to the carb and then out of the carb to itself, where it then "pushes" any air/old fuel back into the fuel tank. The remaining larger diameter fuel line in this setup goes from the metering chamber (has cover with writing on it and a vent-hole) side of the carburetor to the smaller nipple on the purge/primer bulb. Again, on the primer bulb, the longer nipple has a line going directly from it to the tank. This is the return line. The shorter nipple on the bub has a line from it going to the metering chamber side of the carb. If the purge/primer bulb is on top of the carb...small line from carb body to small hole in tank with filter. Larger diameter line goes from the bulb on the fuel pump side of the carb to the larger hole in the fuel tank where sometimes the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank. Otherwise, the line should enter the tank for about 1/2" or so.

There is a connector or something missing from the fuel overflow line from the carburetor back to the fuel tank


There is no such thing as a fuel overflow line.
If the unit has a primer bulb then there will be 2 lines in the tank ( 1 is a main fuel line distinguishable by the length of line that extends into the tank with a fuel filter on the end of it, the other is a return line from the primer bulb that terminates just inside the tank usually with a male to male conector.) The main fuel line will go to the carb and another line from the carb will go to the primer bulb. If any of these lines are discolered, fragile or broken then they should be replaced. Generally the smaller diameter line is the main fuel delivery line and the larger diameter line is the primer system.
