TQ question

So Rusty, Are you saying fuel from the boosters/mains gets in there? Ive never noticed ,looked,or even thought to.

Keep in mind that air/fuel goes in and out of that port when the vac diaphram moves back and forth, so some fuel ends up in there.
(and why I mentioned the melted plastic vac cans on Jeeps) :D
