Hi, I'd like to find an exploded view diagram, specifically of the fuel tank, filter, and fuel lines of a "WEEDEATER FEATHERLITE PLUS" by Poulan. Hope you can help.

Google "Poulan featherlite" or similar search terms, maybe just the model number, should take you to Poulan's website or just type in Poulan.com in your browser, see if you can find their site, then locate model number, see if there are diagrams there.

You'll just get a owners manual...
The lines on these are simple... rip the old out any way you can, go get a kit for it.. the short piece goes nearest the fuel cap (goes on the larger brass fuel inlet on the carb) and the longer on in the tank.. insert the fuel line into the tank, pull it out the fuel fill, put the filter on and push it to the far end of the tank...

If it doesn't prime, just swap the gas lines.
