REFLECTOR: Fuel Tank Calibration

[Dave Black]

We are just about to do our fuel tank calibration, and I realized I 
don't know a good way to stop fuel from flowing from the strake tanks 
into the sump. We do not have fuel shutoff valves on the individual 
strake tanks.

The best we've been able to come up with is to remove the sump and 
temporarily install some longer hoses to the strake tank drains. That 
way we could block those hoses while calibrating the tanks, then when 
done drain the fuel into fuel cans.

But this becomes a somewhat complicated and messy process -- and will 
require a minimum of 6 gasoline cans. How has everyone else done it? Can 
anyone suggest a better method of calibrating the fuel tanks?

Thanks,
Dave Black
