Rather than repurchase the kit with the cheesy guage and fitting, why not spend a little more and get a manifold gauge set a can tapper and a can or two of 134?

You will then have a tool that you can use for the rest of your life. It will pay for itself in short order.

Good luck,

larry, what is a tapper?

A can tapper is the adapter that you get to attach to the freon can. This adapter then attaches to the center manifold hose.

There are several types, but I prefer the small brass one that screws onto the top of the can. There are plastic handled ones that go around the side of the can and pierce by squeezing the handles together.

Good luck,

thanks, larry. what about vacuuming the system
to get rid of the R!2, what do i need?

Joel,

I'm not sure I understand your situation. You said originally that your car was converted 5 years ago leading me to believe that it was properly converted at that time.

If that is the case and it is low on refrigerant, you should not have evacuate unless the system is COMPLETELY empty.

From your more recent post it sounds like maybe it was done without removing the R12, going through the complete procedure and then evacuating.

Which is it?

Have a great day,

sorry larry, i'm trying to kill several birds in one stone.
all my MBs are 134a compliant, but my other vehicles are not.
since R12 is no longer available in canada for several years
now, i traveled to washingston state the other day to
get some quick fix of R12, but to my surprise neither is it available.
hence, the need to evacute and clean the system.

the retrofit here is cheap ( under $300 ) but would rather
do it myself where possible. thanks for the concern.
