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

[Bill Miller - LBCs]

Ooohhh  I made a bunch of these plasma cut from 3/16” plate steel several
years ago for my spitfire friends J  Back when I had access to a plasma
table.

Let me go check in the garage tomorrow evening and if I still have some
left,  I will send you one free
  

I can tell you the 3/16” steel will not warp and leak from experience.

So I want to make myself a fuel pump block off plate for my 1500.  The car
has had an electric pump on it since before I got the car but the shop that
put it on for the owner at the time simply gutted the mechanical pump and
bolted it back in place to cover the hole.  Time to clean it up.

 

The question is this.  I was original thinking of making one out of ¼ inch
aluminum but looking at a variety of aluminum block off plates online they
seem to generally be made from thicker stock.  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.

 

Thoughts?
