has anyone tried the extended fuel tank?

If you have a bi-annual smog inspection it wont pass smog. Unless you retain your factory filler, carbon element and overflow catch system.

 

other option while maintaining your stock tank , pricey install plus the tank.

just jumping in here to say you should get your ass in the motorcycle threads and since you're in san diego we should ride sometime. just got back from the track myself this weekend

 

My E250 holds 36 gallons too. On long trips, my ass usually requires a break long before the tank needs filling. The extended range is nice to have when we take it camping in the Michigan UP and fuel stops are long distances apart.
