2phast, thanks for the reply. my car was retrofitted
5 years ago and seems to be needing 134a refrigerant.
i just cannot push in the black plastic connector of
the gauge onto my fitting. i know i have to pull the
outer plastic until i got both ends connected.
i will re-purchase kit and re-try.
benz300, local shops here charge about $300 to
retrofit a/c, i paid $800 for my car since it incluced a re-built
compressor and new serpentine belt. shop around.
Prayers bring forth enlightenment.
