i recently had to fix a crack in my gas tank, and so siphoned out all the gas. put just enough back in to drive to the gas station (3 mi.) filled it the whole way up. 20 gallons!!! thought that might be of interest to some people. no wonder i never ran out or gas, even when i thought i ran it very empty (18.6 gal) Brian Morgan 89, black also now 90, black
