Have a poulan pro ppb150 thegas lines rotted in tank there are two line in tank a fuel line and apurge line cannot find a schematic showing wich line goes to filter and which line goes to purge and from there where do the lines goe to carb- need instrustion and or a schematic show placement

Clean the carburetor. When the fuel deteriorate a ;ot of time trash is allowed to clog the carburetor.

cheapest way is a new fuel tank from e-bay that has it all installed
you can remove the rubber grommet around the lines to get it out then get a new filter to push on the line BUT will it be cost effective against what can be obtained from e-bay

I just got a poulan pro wild 2375 but all the fuel lines were rotted and disconected. I know one line runs from the bulb back to the tank and one comes from the tank to the carb but I do not know weather it goes to the top fitting on the carb or the bottom I have to fittings at the carb and there close together any help would be appreciated thanks chuck

The smaller line is connected to the fuel filter in the tank and goes on the carb body opposite the end with the hole in the cover. A larger diameter line coming out of the tank is the fuel return line and has the little connector on it just inside the tank to hold it in place there
It goes on the carb body (if primer is on carb) by the bulb.
If there is an external bulb...the small line is the same...there would be a larger line going from the carb body (nearest the end with a hole in the cover) to the smaller nipple on the primer bulb. A third larger diameter line would be connected to the larger nipple on the primer bulb and running to the little nylon connector inside the tank. This is the fuel return line and the smaller diameter line is of course the fuel supply line.

the longer one goes to the carb

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).

Mr Tittle;
It isn't good but it's all there is.
What little fuel system system detail there is can be found here:

If it is a 2375 WildThing find 2375LE Gas Saw Type ?. The last digit of your serial number should be a -1 or -2, the type.

• The filtered hose from the fuel tank 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 the bulb is collapsed it draws fuel from the tank through the carburetor to refill the bulb as the bulb reinflates).
• The pressure side of the primer returns any excess fuel to the tank as it is depressed.

Gas line diagram for poulan 2050 .

The main fuel line goes to the bottom of the tank. The other, sometimes larger line goes to the primer bulb. This line goes just inside the tank, not more than 1"(inch).
