I had to replace mine on my 2008 Puma. I let the dealer do it. The lines from the tanks were fine, but the line from the fuel selector valve (gray) with the fuel bulb internally disentegrated and trashed the vapor separator on my 225 Pro XS. It took $550 to get it fixed, because the vapor separator had to be broken down into every part at Bowden Marine and cleaned. Ethanol is some really bad crap. It will toast the fuel system in a heartbeat.James
