Thanks again, Denny. Exactly what I'd hoped to hear. My thoughts were the same regarding prior use of silicone on the sending unit. Shoot somebody even shot 18 ga. brads into the bulkhead glass just to attach some red oak trim...

Nice to know your configuration is the same. I'll probably run again this week and take a couple full auxiliary tanks in case I have a recurrence. Should be able to drain the balance of the tank in 20 miles or so, get me to the nearest banks and have a shot a some tune before the move back south.

Really like the vent whistle idea. I'll look into that. Not sure what coal tar epoxy is but I'll check with my epoxy guru.

As far as the silicone caulk are you referring to the home standard DAP or whatever caulk with silicone or 100% silicone. Thanks again.
