Sorry to add more work, I'm waiting on my fuel pump to come back from the shop, and my exhaust
to get back from the welders. There's no winning ... I'm wondering now after all these years if when
I installed my exhaust whether there was any binding that later led to cracks ...

Seems everything in the plane with an "O-Ring" in it is leaking as well ... Fuel drains, valves, etc. (I only
run Avgas, but this is 16 years since I built it ...
