I used a small compressor dialed down to 15psi and a spare reservoir cap with an
assortment of fittings to attach a standard air fitting. It doesn't need to seal perfectly,
in fact a bit of air leaking out is probably a good safety for the tank seals. Worked like
a charm on my '82 when I allowed air into the clutch master cylinder from letting level
get too low. Just fill tank to almost full, apply pressure, then bleed, watching that level
doesn't get too low again (need two people). I was able to do it one pass by making
sure tank was full before starting.
