[Spridgets] An aluminum question for the engineering/machinist type out there

[Rick Fisk]

I drilled a hole in my steel cover, tapped it for 3/8" NPT pipe threads, and screwed a brass barbed fitting in it for a vent hose.

Would ¼ inch tend to deform/cup/warp over time and leak? I’m fine with using thicker stock, I’m just wondering if it’s necessary.  I know that some people use the chromed steel fuel pump block off plate for the big block Chevy on the 1500, but it doesn’t fit the opening correctly and just doesn’t look right to me.
