you will need a complete fuel line. that model is old and fuel lines become brittle. the noise in tank is the fuel filter. most mower shops have the correct fuel line. poulan is owned by the electrolux group of compnies, so any good husvarna dealer can help you. its not an easy job. get quote, as a domestic saw like yours can be replaced by a 150 dollar saw from bunnings. go to www.husqvarna.com.au for nearest dealer
