Hunter, no extender on the 212 but she'd still take 250 gals without it!

Has anyone done a "full to fumes, and back" calibration tank to see how big the tanks really are, how much is "useable", etc... Don't know about getting the rail filled/primed if you run it dry by sucking air from an empty tank. Do the '03s have a similar weak lift pump life 2nd gens or is there a boost pump in the tank? I guess the computer hiccup thing doesn't help, either.

Cheers!
