Great suggestion, but it already has a new cap (.04) put on last week when I suspected and thought I fixed the problem.
Today, using a cell phone cam, I found the crack at the bottom of the tank near the firewall.

I already have a tank on the shelf, so this week I'll do the dreaded job...

Then hopefully back to the track for MayFast.
This time I'll try to focus on the line and keeping it smooth (see if I can keep the chief marshal from remembering me as 'that new Porsche guy who keeps spinning off the track').
