Dear Answer Army,
How to replace the Fuel line in the Gas tank on a Husqvarna 235R Brush Cutter. I dismantled the whole trimmer engine. Found that the tank and the engine mount is all one unit. I found the Gas line and the filter loose (not attached to nothing) in the tank. Don't know how the Gas goes to the carburetor. The carburetor has only a return (overflow) line to the thank.
Was reading the whole manual and searched websites for answers; no luck.

Please help.
Thank you for your time on this matter.
Sincerely,
Walter
