SOURCE: GAS LINE PROBLEM

Hi this is the way it should go: 1 from the filter in the tank to the bottom of the carby,2 from the top of the carby to the inlet on the primer,3 from the outlet on the primer back to the tank as this is the return line nothing goes onto it.

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:

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

Testimonial: "Yes, was almost exactly what I needed. Did have to search to find which port on the carburetor was the inlet an the other the outlet."

SOURCE: Craftsman Brush Wacker routing of fuel lines Model

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.

Need diagram of fuel lines from tank to primer bulb and carburator on a Poland chainsaw model 1950 wood shark


There are 7 different types of the 1950 model (types 1 - 7) and it came with one of these 2 carbs Walbro or Zama. The carbs are different as are the fuel line connections for each one.
Although this video is for the promer bulb you can see the routing of the fuel lines.
http://www.ereplacementparts.com/article/4262/How_to_Replace_a_Primer_Bulb.html

You will have one line from the fuel tank connecting to primer bulb the 2nd line going to the carb. If you connect it backward it does not pump fuel into the carb.

I have a weedeater model Featherlite 711334 and the gas lines crumbled to nothing. Not sure how the set up was inside the gas tank as to which line goes where and hooked up to what inside the tank.


There are two lines from the tank to the carburator. One picks up gas and fills the prime bulb, the other is a return line. The pickup line should have a filter on the end of it that is in the tank. The other line just dumps back in the tank. Usually the reason these lines deteriorate is because of ethanol in the gas. Make sure you're using ethanol free gas.

Fuel lines inside of tank fell off


This is the typical fuel line routing2.gif on many models: One line ( the one with the fuel filter in the end of it) comes out of the fuel tank2.gif and goes to the lower port on the carburator. The second line goes from the fuel tank to the bottom fitting on the primer bulb. The third section goes from the top port on the primer bulb to the top port on the carburator. Hope this helps and best wishes.

Craftsman 32cc Weedeater -- need fuel line diagram


The smaller diameter line (fuel supply) goes from the fuel tank (w/filter) to the carb body. Another larger line (purge line) goes from carb body to the right nipple on the primer bulb. Another large line (return line) goes from the left nipple of the primer bulb into the fuel tank. co0mpleting the purge circuit. This info pertains to my 2006 Craftsman 32cc with Zama carb.

Need manuel to show how gas lines are run to carb. & pump bulb


HOW TO CHANGE FUEL LINE ON McCULL0UGH 2014 CHAIN SAWS.

I have successfully changed the input fuel line by purchasing Tygon tubing from a local lawn equipment dealer. I did not see the box he cut this from, but the tubing I bought measures 0.190" outside diameter. I gave him a piece of the old tubing and he matched it up. A 18 inch piece cost me $1.19.

The routing of the fuel line involves three pieces, one piece from the fuel priming bulb to the carburator is 3 inches long, a piece from the fuel priming bulb to the gas tank is about 4 inches long and the piece from the fuel tank is about 7 inches long. The priming bulb sucks air and fuel from the carburator and dumps it back into the gas tank. Therefore, when you press this repeatedly, gasoline will eventually appear in the bulb when the gas line to the carburator is full of fuel. The bulb may not completely fill, there will always be a little air in the bulb.

The fuel line in has a filter on the end within the fuel tank. If you find this has broken off, as I did, you have to turn the tank upside down and shake the filter and any pieces of broken fuel line out of the tank.

Replacing the fuel lines within the carburator compartment is easy if you remove the carburator first. To work on this you must remove the two screws holding the carburator to the engine. You may need to use a small screw Torx driver, although on my chainsaw, there was also a long straight slot on the head. The line from the priming pump to the carburator goes to the left hand line on the carburetor (as viewing from the top with the blade extending away from you. The input line will go onto the right line on the carburator.

The two lines into the fuel tank are located in the middle of the tank left to right and one about 1/2" above the other. The upper hole is for the fuel intake line. The fuel line passes through this hole and a second hole visible within the tank fill hole.
This was the trickiest hose to replace. How I did it was to use a piece of #12 copper electrical wire stripped out of its insulation. This was fed through the 7-inch Tygon tubing piece until it emerged from the far end. I also found it necessary to put a bull nose end on the Tygon tubing in order to get it to feed into the tank hole visible from the tank fill hole. Why? I don't know, but after 20 minutes of trying to feed the hose (both naked and with the electrical wire inside) into that second hole, I gave it a bull nose on the tubing by careful cutting with sharp scissors and using a sanding block. Perhaps McCullough has a special tool to do this, but a call to their 800 number could not get a knowlegible answer from the parts person.

After the Tygon tubing shows up in the tank fill hole, I pulled it further with needle nose pliers and was able to pull the copper wire back out of the tubing. I then cut the bull nose lead I put on the Tygon tube and installed the filter onto it. I found that a little oil on the nozzle and the carburator lines makes the tubing easier to slip on. The stuff the filter and Tygon tubing back into the tank fill hole and towards the front end of the tank so that it drops into the bottom portion of the tank. After attaching the intake line to the carburator, use the needle nose pliers to pull excess line into the tank.


Reassemble the carburator to the engine and you'll be good for another 10 years of happy chainsawing!

Carburator


Hi,

To my knowledge, the gas tank vent does not hook up to the carburator, it is just a means of escape for trapped air inside the gas tank, so normally it is just left hanging.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
