Hi Ted, the best route is one that has nice easy bends, no sharp kinking type, and goes as straight as possible directly to the carb, no long downward loop to facilitate an external fuel filter, put the filter above intake manifold. Good luck

SOURCE: Poulan chainsaw gas line routing?

There ARE two holes in the tank. One samll and another larger. One is on the left side and the other is on the right. Look carefully and you'll find them. As far as connections of the fuel lines:

The line from the fuel filter in the tank goes directly through the small hole in the tank to the top nipple on the carb thus giving the carb a constant supply of fuel when running. The primer bulb is used only for "priming" and does not play a part in the fuel flow after that function. The bottom nipple on then carb then goes back to the nipple on the primer bulb which is clearly marked "Carb". The above connections are made with the smaller diameter tubing. From the primer bulb, marked "Tank", the larger diameter tubing is routed to the large hole in the tank. The tubing goes into the tank only 1/2 to 3/4 inch. As far as getting the tubing through the holes in the tank, cutting the tubing at a slant. But no matter what you do it is still a witch. Be patient, use some Vaseline and avoid the temptation to get out the drill and **** the hole to a larger size.

This is an example of a typical fuel system with a few suggestions:
http://www.fixya.com/support/r3706813-2_cycle_fuel_system_repair

Your basic model number is 600465. I only saw 11- prefixes used with 600465s, no promises I did not miss any. There are a few different suffixes with the 600465s. I think the suffix is on your saw immediately after the basic model number somewhere (On older Macs it is usually on the bottom along with the serial number. The dash of the serial is often the correct prefix). I must defer to you to find your exact IPL, here:
McCulloch IPLs
http://www.ordertree.com/modelinfo/McCulloch/139.59.htm


I chose "11-600465-09" as an IPL example:
http://www.ordertree.com/modelinfo/MCC/11-600465-09-MAC-4600-10%2F94-to-Current-IPL-211594/139.11-600465-09-MAC-4600-10%2F94-to-Current-IPL-211594.1.59.1.html

I find these helpful when getting into an area of repair I am unfamiliar with. Also all components are displayed and part numbers listed.

If you find different size hose a small sample of each taken to a local saw outlet should provide something suitable. Please ask how long they feel any replacement should be (usually 12" ample). HTH

SOURCE: ON a Poulan 220 Pro all of the fuel lines are

Your fuel lines are routed like the schematic below. I suggest you replace the filter, all hoses (2 different sizes), and the purge button (bleeder).
http://www.fixya.com/support/r3706813-2_cycle_fuel_system_repair
Let us start with the bleeder. The 2 hoses that connect to the bleeder are different sizes (Important). If the nipples are the same size connect a hose temporarily to one of them and place the free end in a small container of mix (please be careful with open gasoline and as soon as it is no longer needed put it out of harms way.). Squeeze the bulb if it blows bubbles that is the return side, it gets the large hose and attaches to a fitting on the tank. If it appears nothing happens but when released fuel is drawn into the bleeder it requires a short section of small hose and attaches to one of the carburetor fittings.
A second small hose goes through the tank and connects to the carburetor just like the video including the filter. It feeds the carburetor like it has since before bleeders were installed. I am not certain which carburetor fitting connects to the tank or the primer, please leave them long enough to swap until the saw is running. Logic says the upper most fitting (air bleed) goes to the primer but that is not always true. The Poulan drawing is deceptive it appears the filtered line feeds the bleeder it does not!!!

The IPL (exploded parts list) for your saw is the only detail for fuel line routing and it is sketchy at best. Fuel components and part numbers are listed but are on different illustrations. They are also beneficial with disassembly/reassembly.
A link to a Poulan "PP220 Gas Saw Type 5 follows (may not be your saw):
http://www.ordertree.com/modelinfo/PWE/PP220-Gas-Chain-Saw-Type-5/75.PP220-Gas-Chain-Saw-Type-5.1.59.1.html

If your saw is not a Type 5 you can find the correct IPL here:
Poulan.com
http://www.ordertree.com/modelinfo/POULAN-WEED-EATER/75.59.html
The dash number of your serial number is the type.

If you have more questions or need additional help please reply below and I will get back to you. HTH & Good Luck.

No drawings or pix, but will try for description--the line from the tank that has the fuel filter is the main fuel source which goes to the upper connection on the carburetor. The lower carburetor connection goes to the intake side of the primer bulb, and the outlet side of the primer goes back into the tank, which has no filter inside the tank. The main problem is determining the correct primer port to connect back to the carburetor. When everything is connected, try priming the carburetor. If fuel fills the bulb, you have everything connected correctly. If nothing happens, try switching the two primer port connections and try to pump fuel again. If still nothing, hook the main supply line from the carburetor over to one of the primer ports and try for fuel again--if still nothing, switch the main supply line to the other primer port and pump again. If still nothing, check for a plugged fuel filter in the tank. If the filter was plugged, then go through the previous procedure again. Make sure to replace the fuel lines with original rubber lines, not plastic. Hope this helps!

Fuel line routing diagrams for 86 yamaha fz600


You can route it any way you want really. I'm not familiar with your specific model but if you don't have a fuel filter (you should) or a fuel pump to worry about it's just a matter of finding the easiest path from the inlet nipple from the carburetor rack to the petcock on the tank...

That's an awesome number of innuendos in one sentence!

Need a diagram of fuel gas lines on a 131 poulan


Lots of research has shown a lack of diagrams on fuel line routing. Your carburetor has the purge/primer bulb on top of it. Just to help you understand how it works....the bulb uses a vacuum effect to pull fuel from the tank directly into the carburetor and the check valves in the plate under the bulb (known as the primer base assembly) push any air and old fuel inside the carb back into the fuel tank. On your model, the line inside the tank with the fuel filter on it will come out and go to the carburetor body BELOW the base assembly. The other line coming out of the tank (fuel return line) will go TO the nipple on the base assembly. The lines should be nice and soft and so should the bulb. They all have to be replaced periodically as alcohol, heat and age deteriorate them. Please post back if needed.

No gas getting from the gas tank to the carb. replaced hoses and filter already. can not even draw gas with primer button.


You either need a new primer bulb (leaking air) or you have the fuel lines routed wrong. Here is the correct fuel line routing just in case:
Small diameter line out of fuel tank (has filter in-tank on end) connects 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. 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 the line is held in place with a nylon nipple connector that keeps the line from pulling out of the tank

I need info on a Poulan Pro 445 fuel line routing


I'm so confused. This is reported as a Poulan and McCulloch pole saw, which one? Is it a pole saw? That is the only 445 Poulan I can find. It is reported as an electric but has a fuel routing problem.

If it is a Poulan Pro gas pole saw it is here: PP445 Gas Pole Pruner
The fuel system routing is terrible, but it is all there is.
Fuel Routing follows:
Tank to carburetor (hose in tank with filter on free end)
Carburetor to primer (primer draws fuel from the tank through the carb)
Primer to fuel tank (returns any excess fuel to tank when pushed) HTH

Need gas line routs for a craftsman weed eater


The longer, (and sometimes smaller of the two), fuel line goes from the carburetor to the tank with the fuel filter attached to the end, inside the gas tank.The other line, ( sometimes larger), goes from the primer bulb to just inside the gas tank, about a 1/2 -1 inch inside with coupling attached to the end. Coupling keeps line from pulling out of tank.
