I think the only reason it fit before was it was pulled to its fullest extent.
But because of the angle to work with, there is just no way to pull it that
tight.  I wasnt sure if a line from a full sized truck would work.  I'll look
into that.  It's a plastic line, but a steel tube inside.  It has to go into
the hole far enough for this stupid pin to slide through to hold it in place.

I've never worked on a BRII. I knew the full size ones were plastic/metal,
but not if they'd fit.
...and, they're a real bear to bleed.
