Gas Tank Drop   Today I started my most ambitious project to date -- dropping the gas tank to deal with a non-functioning fuel gauge.  I know that's just another day at the office for many of you, but I was a little intimidated.  It turned out to be much easier than I thought it would be.   Following the suggestion of my mentor, Don, I used a floor jack and plank to support the tank while I loosened the straps.     I dropped right out easily.
