Thomas Compressor/Vacuum pump

Donald,
Your idea has merit,the Grainger catalog has several small filters that
would work.

J.R.,

The DOT air line fittings we got came with brass ferrules. I assumed they
are meant to be used with the DOT plastic air line, but I guess there could
be a metal DOT line. We haven't had any problems with any of the fittings
leaking though.

Thomas,

My '76 has an Electro-Level I system with the compressor located under the
twin bed on the driver's side. I think I'm going to order Cinnabar's
upgrade kit and hope my mechanic can follow directions well enough to put
all the pieces together. I'm tired of trying to find the leak using leak
detector.
