Tom,

I'm sure this is true. It is the outer ne that demands changing.

I don't think that I will replace it with a car filter because of the uique 
size. If i could find one the equal size then I wouldn't hesitate. And I'd 
probably save $$ doing it.

What? String droop. Yarn tied to what, from where to where, Mr. Engineer 
Person?

Do the words, draw me a picture, have any meaning here? I think that you took 
one giant step. How did we go from car filters to my cutting holes in the 
wall?
Does the drooping string go from the outlet to the car filter then out thru 
the whole it the wall? But won't the snakes, scorpions and spiders be able to 
get in by climbing the string? Or will they get zapped when they get to the 
outlet.
I'll talk to ya later, Mr. Engineer Person.
