mod 49

[Gramin@aol.com]

I am surprised that this mod. does not recommend a different filter.  It is
not a complete solution to fit two, if the "reserve" one is found to be faulty
when you switch to it, due to an air leak.  A minimum requirement would seem
to me to be a mandatory test for an air leak after reassembly of the filter as
my message of  26th June.  I have suggested this could be the cause of G-
MAVE's demise but have not had a reply.
