• The hose in the tank with the filter on the free end connects directly to the carburetor input connection.
• If the saw is equipped with a primer, the output line from the carburetor connects to the suction side of the primer bulb (once bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb refills).
• The pressure side of the primer returns any excess fuel to the tank as it is depressed.

This is an example of a typical fuel system with a few suggestions:

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:

I chose "11-600465-09" as an IPL example:

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

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!
