Default R134 leaks

As it was explained to me...
The R134A molecule is VERY MUCH SMALLER than the molecule
for R12. It leaks out thru the hoses because they are too porous
to contain it. That's why you can't just put R134A in a system
not designed for it. Maybe you can replace all the flexible hoses...dunno.

Compare the cost of just adding more at intervals to your other
options. May not be such a bad idea to keep what you've got.
