I wonder why they upgraded the fuel line on the '08's. I think it's 'cause the the old one has a crappy plastic connector that connects to the injector that breaks very easily. the new one on the 08's are made of braided line with pressed fittings that are less likely to break. by the way if you break one the HD shop won't sell the connector, you have to buy the whole line with with the connectors for the tank and the injector for 50 bucks....what a scam!!!!
