since oil is lighter than water, all the water will sink to the bottom
of your gas tank

just find the lowest spot on your gas tank and drill a few small
holes... this will drain all the water off.

if you don't have a drill.. get a hammer and a big steel nail.. just
hit it real good it will finally pop through... make about 6 holes..

problem solved

to plug the holes up.. just stick the nails back in the holes.. they
will hold

Yeah, my troll sensors were tingling, too, though perhaps we are being
too cynical. I was going to suggest to him a couple bottles of drygas;
car won't seem sluggish after you drink those.
