Okay Alan,

I'll bite, but if you're going to tell me it's your finger, then I'm going
to ask which of your arms is 5-foot long, with three elbows, for those not
so easy to reach tank locations!?

Now get back to work!  ;>)

best regards,
Mark C.

Hey Fred and David,

This digital sensing device to prevent overfilling exists already. I've been
using one for years and it is foolproof, infinitely adjustable on-the-fly
and cheap. It's in everybody's tool kit.
