Adam, this seems like the logical thing to do. However, I think I will
expose my lack of VW knowledge and verify what the sump plate is :|

Are we talking about the cover plate the holds the strainer? (that's what
I called it 30 years ago on my bugs) One of disavantages of a great
running van is that I seldom have to be under it, and so I am not well
versed in VW'ese

If it is not the 'strainer' cover, I am willing to learn :-)

Thank You,

John
