[DML] Re: AC Rubber tubing

["Jim Reeve" <dmc6960@xxxxxxxxx>]

The spliced lines are quite nice for ease of install.  Andy is right
that the hardest part is getting the low pressure line through the
frame by the gas tank (which really wasn't that hard).  It helped
having Andy assist me, in that I could bend down the frame slightly
(not a permenent bend, just a flex) and guide the end over the tank
plate nuts while Andy actually pushed it through.  It can also be
difficult to separate the nuts and the lines.  You need to spend $75
on a 32mm, 27mm, and 22mm wrench.  19mm is also necessary but I
already had one of those.  There is not much room to work the wrenches
but it is possible (hey, they got them on there didn't they?). On the
first car I did a few years ago, I could not separate the high
pressure line from the evaporator.  I got the nuts apart, but the
lines would not disconnect.  With more time they probably could have
come apart, but I didn't have any then.  My car which I'm in progress
with was no problem.  If your doing all this, replace the accumulator
and orifice tube as well (unless you did that with your original
conversion).

Other misc. notes....

Be sure to keep the main high pressure line away from the steering
shaft.  Many owners have had sudden AC failure when this hose was warn
through by the shaft.

Also, John Hervey has not been as responsive as he has been in the
past.  When I made my original order almost everything came as it
should.  I emailed him many general questions about the parts and two
that were missing, no responce.  I called him a few times then
eventually got through to him to get one of the parts that didn't
arrive, but I still dont have the other one yet.

When I arrive in Chicago, every component in my A/C system will be
brand new except for the evaporator, which I removed and throughly
cleaned.
